Official Overclocking Thread- ALL questions go HERE

[Sgt.Igneri]

Follow this link for an overclocking guide with Intel's Core 2 CPUs. (http://www.techreport.com/articles.x/13815/1)

In light of all the OCing threads and questions, i thought i would make a tutorial here.

Here are the requirements:

1. At least one fan blowing into the case, and one blowing out.
2. Good cooling method. I would reccommend not OCing unless you have a quality cooler.
3. Good temperatures. I would say around 40-50C load on Barton AMDs, and 50-55C on P4 "C".
4. A decent ambient temp(room temperature)
5. A STABLE motherboard. Abit and Asus are reccommended.

Now, lets get going.

Pentium 4 "C" Overclocking

First, get very familiarized with your BIOS, your going to be in there alot, and i mean that. Before you start, make sure you have all newest mobo drivers available, and check what the newest BIOS fixes. If it fixes something you should be conserned with, you need to do a BIOS flash (instructions will be on manufacturers website) Go into BIOS and set all options to "user defined" this way you now have full control of the OC***ALSO SET THE RAM:FSB RATIO LOWER BEFORE YOU START, KEEPING IT AT 1:1 CAN RESULT IN THE BEEP OF DEATH:eek: :x***

Next, download a CPU stress test such as prime95. This will raise your CPU temps to the max while testing system stability. The slightest fault found will shut down the test. Run prime95, and monitor your temps. They shouldnt go above 55C, unless you have an Abit IS7 or IC7 series, they display 10C higher then they really are.

Get into BIOS again. Set the AGP/PCI to fixed, on 66/33mhz. Now start the OC. P4 multipliers are locked, so you can only OC by changing the FSB. I would say go up at about 20-50mhz intervals, ONLY if you have a P4C. If not i reccommend lower increments. Ok, so you up it 30mhz or whatever. Now you exit BIOS and do a simple run in prime95, for about 15-30 min. while monitoring temps. If it doesnt find an error, proceed to OC more, if it does, then you MAY need to up the voltage core on the CPU. Ok so as you get higher in your OC, each time, run prime95 for a longer and longer time. Eventually you will start getting instability problems. Now its time to up the voltage.

***NOTE***CHANGING THE VCORE RESULTS IN TEMPERATURES SEVERAL DEGREES HIGHER THEN BEFORE, IF YOUR TEMPS WERE BAD BEFORE, DONT EVEN THINK ABOUT DOING THIS. Go into BIOS, and under the soft menu, look for the Vcore. Up it to the next one available. Run prime95 for about an hour *closely* monitor your temps. If they stay under 55C, move on to OC some more. Its pretty much rinse and repeat from here. Once you get to your final destination, its time to do a serious stress test, like 12-24 hours to ensure complete stability. Now, lets start tweaking everything else out to match the OC.

Go into soft menu, were going to start tweaking the RAM. Start to set it to a tighter ratio, getting closer in sync to the FSB. Keep doing this until you cant anymore.*5:4 divider is reccommended for new OCers*

Check stability. Go into BIOS again, this time go to "advanced chipset features" Set the RAM timings to user defined. The higher the number, means looser. Looser= less memory bandwith, lower=tighter= more bandwith. Pay attention, timings are key to getting performance out of an OC. First find out your CAS timing, it should be on the manufacterers website. If its not at that rated timing, put it there. Now seperately tighten each timing and test stability.

Those are the basics for the P4.

AMD AthlonXP/Sempron Overclocking

NOTE:Most AthlonXP's and all Semprons have locked mulitplyers now.
AMD is very similar, but a little diferent. The biggest thing youll notice is the layout of softmenu in BIOS. You dont have to only up the FSB to OC, AMDs multipliers are unlocked so you may change them. Just in case your wondering, you get the CPU speed from multiplierxFSB. To use the OCed CPU, you need to select "enabled" for one of the options in BIOS(cant remember name, just look to the right, itll show an explanation of each setting) Dont forget to chose a good FSB:RAM ratio that wont screw your RAM up.

Ok, so choose what you want to do. Up the multiplier and keep the FSB the same, or up the FSB, which will also up the clock speed without touching the multiplier. Basically, just OC with the FSB unless you want to keep the FSB at stock.

Same thing, slowly apply the OC, instead of 20-50mhz increments, i would do 20mhz increments, or less, on an AMD. Blah, do the stress testing and monitor temps, etc etc. Once it gets unstable try upping the vcore to the next level.

Once at destination, peform a 12-24 hour stress test with no faults. If all goes well, move on to tweak the RAM(read P4 sec. for details) if it doesnt underclock in 5mhz increments till its ok.

AND, there you have it! Wasnt too complicated was it? Those are just the basics, as you get more experienced youll learn more and better techniques.

AMD Athlon 64 Overclocking

Athlon 64's have their multiplyer locked while the FX's have their multiplyer unlocked.
Technically Athlon 64's don't have a FSB. They have a base clock which controls the CPU speed and a hypertranport (HT) link which is the path from the System to the CPU. The base clock on all Athlon 64's is 200Mhz.

The BIOS will either list the HT speed as a multiplyer (1x,2x,3x,4x,5x) based off of the CPU's base clock or it will say the full speed (600MHz, 800MHz, 1GHz). If your BIOS lists it as a multiplyer, it would be a good idea to lower it one notch so that it does not interfer with your OCing. Lowering the HT speed a bit will not hurt performance, unlike lowering the FSB speed on other CPUs.

The base clock controls the CPU speed just like the FSB does on other CPUs. It can be listed as Base Clock, CPU Speed or FSB in the BIOS. Increase it in increments of about 20Mhz before booting into Windows to see if it is stable.

Higher memory speeds will have a big impact on performance because of the Athlon 64's onboard memory controller. Memory speed is determined by a ratio (in 6ths) of the CPU's base clock. So an example of some of the ratios would be: 4/6 (133MHz), 5/6 (166MHz), and 6/6 (200MHz).

If it become unstable and crashes then increase the voltage slightly. Temperature will rise more with higher voltages of course. If you have an Athlon 64 FX CPU and you have hit a wall then you can try to increase the multiplyer to see if you have any more room.

ATI/Nvidia Overclocking

Much easier then OCing the CPU, but it canbe more dangerous. Make sure at LEAST one fan intake and one exhaust. Youll need special applications to OC a gfx card.

For nvidia, youll need either coolbits: http://www.overclockers.com.au/techstuff/a_coolbits/ OR Rivatuner: http://www.guru3d.com/rivatuner/

For ATI, youll need Rage3d tweak: http://www.rage3d.com/r3dtweak/

Ok, so lets start. OC in 1-5mhz increments, DO NOT take a big step, you screw it up big time and itll fry. You screw up a CPU OC and just reset CMOS on motherboard, a bit different, especially on expensive cards. After each OC, run a game that is gfx dependant, or a benchmark like 3dmark03. If you get artifacts, like messed up gfx, then the card is unstable and overheating, and youll start undercloking, if its fine, move on. So instead of monitoring temps like on a CPU, your going to look for artifacts in a game. Do the same until you find instability, then underclock 1mhz at a time till its stable.

And thats all for gfx card OCing.

Questions anybody???

[Owskie]

no sir!

[ankalar]

I have a question, why would you up the multiplier instead of FSB on an AMD chip? One of the main points of overclocking is getting your FSB higher, not just the clock speed. You're supposed to lower the multiplier a good deal and see how high you can get your FSB, then raise the multiplier to a decent level and see if it runs.

[Sgt.Igneri]

If you read the whole thing, i said you can do it either way. So lets see: you want to OC a 2500+ to a 2800+ then you would only up the multiplier... You want to OC the 2500+ to a 3200+ then you up the FSB and keep the multiplier at 11 or lower.

[ankalar]

Why even suggest the other way if it is inferior?

[Sgt.Igneri]

Why would it be inferior? Maybe to US it is, but not to someone new.

[Mac]

to someone new they wouldnt have a clue thats why we tell them that lower multiplier and higher fsb is better for performance in applications such as gaming

[TheRook]

Ok boys and girls... here is a challenge for you... i want uber performance for **** all!

My current set up is...

A 2000xp+ AMD processor
ASROCK K7S9XE MOBO
768mg 2100 DDR
and the graphics card doesnt count cos i know i need a new one...

I currently have my FSB at 166 = 333 mhz

my mobo doesnt allow adjustments to the Multiplier but thats ok as its already set at 12.5 which is damn high

so if you work it out my fsb @ 166 multiplied by 12.5

that means my current speed in ghz is

2075

making my 2000xp into a 2600xp

which is a moderate boost IMO. What i want to know is...

My CPU supoprts 333mhz fsb (which its set on...) how can i get it up higher? safely?

i recently tried setting it to 170 x 2 = 340

which it seems to be stable on... @ 2.12 gig but when i tried to set it to 175 windows wouldnt load in... it would get to the windows loading screen then restart?

What do i need to do...

ALL help and suggestions will be much appreciated...

but please dont say "buy a barton 2500 cos dey is 1337" because i dont care...

oh by the way im on Stock Cooling (standard HS/F)

Average temp is about 38-40 degrees C

Thanks

TheRook :bounce:

[TheRook]

come on people? oh well its about 6ish in the states so guinny and should be on soonish... as he knows his fsb overclocking shizzit

and i was hoping zool would be on but i left it a bit late as hes in sweden i believe and its about 12.30-1.30 there now :/

but come on people i know u know ur overclocking...

i know my technology troubleshooting crap... but i need overclocking info...

[Asus]

Your RAM may be holding you back. If you want, you could try to increase the timings. That may give you more room but not sure how that would effect the actual performance (with the higher timings and all).
Maybe look into unlocking your CPU.
What chipset is on that board anyway? nvidia/via/sis

So far it looks like a good OCing job ;)
Assuming you do not have the stock HSF on there.
Have you increased the voltage at all (cpu or memory voltage)?

[Sgt.Igneri]

MAYBE, you can read my guide dedicated to overclocking at the top of the page.

the k7s8xe board is a sis board...

i have stock hs/f on there...

i havent increased the voltage to either...

not wanting to sound ungrateful sgt igneri... but i dont find your overclocking thing "that" helpful... but i have read it...

im not too sure i an increase the voltages... ill have to restart to check my bios for that one...

TheRook
:bounce:

p.s. anyone know why when my fsb is at 175 when loading into windows it just restarts?

[Sgt.Igneri]

Ok, you dont find it helpful. Its ok, i know you know more then most people, but you still could have posted this question in the guide. I can answer any of the questions, but i refuse to until this is posted in the guide.

you need to but pc2700 or 3000 or 3200you could try running a 4:3 ratio that might allow it.

Yuor ram is desighned to run at 266 MHZ your running your system at 320+ MHz there will be some 'give ' in the ram but not that much.

[TheRook]

ok i havent seen a feature to set the ram at a ratio...

the cas latency is currently set a 2.5T

ive looked in the voltage part of my bios and i cant adjust any of it...

ok im at 171mhz fsb at the moment at 174 it reboots loading into windows...

i will solve this problem!

so you think its my RAM slowing me down?

(i know i need some more... i was looking into 2700 so i can get 1gig or so in my pc...)

TheRook
:bounce:

[Sgt.Igneri]

First off, you need to run a stress test, like prim95 each time you OC. You have no way of really telling its unstable and since it is OCed pretty high with the stock HSF, it most likely is quite unstable. Second, buying a 256mb stick of PC2700 and combining it with PC2100 RAM will do nothing. The PC2700 will run at PC2100 speeds. Third, make sure all settings are turned to "user defined" then you can change voltage, etc.

[TheRook]

ok ill get prim95 right away...

its actually very stable...

(i myself am surprised...)

im not jsut gunna buy 1 256 stick of 2700 :) i may not know too much about overclocking but i do know a fair bit on pc's... overclocking is where im currently lacking... so im find out as much as i can...

the odd thing about the ASRock K7S8XE MoBo is that it has 3 memory slots... it can hold a max of 3 gig 2100 ram... 2 gig 2700 ram and 1 gig 3200 ram...

basically 2100 i can use all 3 slots which is what im doing now... 512,128,128

with the 2700 i can use 2 memory slots

and with 3200 i can only use one...

and as 1gig mem sticks arent that cheap... im sticking with the 2700 so i can get 2 512 sticks...

so... if i get faster ram... i can basically increase the FSB more?

the fsb on the cpu where it says 333mhz (2x166) isnt actually the max it will go at? but the speed of the memory which limits it?

so if i spent more cash and got the 1gig stic of 3200 i would be able to have it at 200fsb (x2) and it wouldnt have a huge problem although it would mean better than stock heatsink and fan :)

TheRook
(correct me if im wrong in understanding this...)

[Sgt.Igneri]

No. Getting a higher RAM speed does nothing with OCing, unless you want to run a 1:1 ratio. If it has better timings, that can help though.

So its the other way around. If you get higher speed RAM you will be able to OC your RAM higher.

BTW, dont even think of saying the word "stable" until you run 6-12 hours of prime with no faults.

[TheRook]

lmfao...

um i got prime95...

set it going and um... that was it... just froze... about 3 sentences came up and numlock wouldnt turn on and off...

so i take it thats not stable...

TheRook

:flame:

[TheRook]

possibly chose the wrong setting ive taken the fsb down to 166 and set it running my cpu usage is supposedly at 100% but i can do all this fine.... altho its actually using my page file....

hmmm


seems ok tho... how long does it take to do a test?

[Sgt.Igneri]

I suggest resetting CMOS, start everything frfom beginning, OC and run prime each OC.

All of the stuff you asked, was answered in the guide, you just didnt read it.

[TheRook]

oh... well

i cant be bother to do that... each time... its running prime95 just fine at 166 so ill leave it at that and just buy some better memory....

i mean 2000xp to a 2600xp aint bad really... for a "first time" cpu overclock...

TheRook

[Sgt.Igneri]

Your at your final destination for now, so run prime for like 12 hours.

[TheRook]

and what if my cpu gets too hot? will it auto shut off? or will it jsut fry like a mof***er?


:)


Therook

[Sgt.Igneri]

Monitor the temps for about an hour, however high they get then will pretty much be as high as it will get throughout the whole test.

It shouldnt be any higher then 50C.

[Draklyne]

It shouldnt be any higher then 50C.
Holy #$^&!!!

Are you serious? Without OC'ing, my motherboard reports a temperature of somewhere around 54C. Argh, and I thought those two intake fans were enough...

[Sgt.Igneri]

Ok, lol. My abit IS7-G also reads 55C, but it reads 10C higher then what it really is. What mobo is it?

[TheRook]

theres this simple thing called AIRFLOW...

its where cool air comes in and hot air goes out...

i think your problem is you probably dont have a fan on the back of your case blowing the hot stuff out...

therook
:smoking:

[Draklyne]

Ahh, the condescending tone burns. Seriously, that's insulting. I know about AIRFLOW. It involves various imps from hell.

But I never said I wouldn't do anything about it, so I've switched one of the intake fans to exhaust. Haven't looked at mobo temps yet.

[Sgt.Igneri]

Draklyne what mobo do you have?

[Draklyne]

I'm using an MSI 845G something something mobo. P4, and a hot Radeon 9700 pro.

[Sgt.Igneri]

Go to www.hardforum.com and ask them if your mobo reads higher then what it really is. Im sure thats the problem.

[Washuu]

Well, hl2 is about, and im at a 2600+amd system, with a ti4600 video card..
i know how to up the video card a bit, which i have replaced the stock heatsink/fan, with a nicer set, and memory heatsinks...
but, i was really wondering, how should i go about OC'ing the processor, which i might want to do, so i keep my FPS in hl2, at 30fps or greater..
i would mainly like to increase my FSB, to 400, from 333, should i leave the multiplier the exact same?, and how much would the temperature of processor go up? currently at 35C, but before i overclock , i am going to buy some artic silver 3 + lap the heatsink.
- advice on my exact setup.. please.
- volcano 11 heatsink/fan currently running at 3500rpm, goes to 5200rpm max.
- i have a bunch of case fans, im in the basement..

argh, forgot something, the volt level thing, did confuse me...

[Sgt.Igneri]

If your going to OC just to get more FPS in HL2, then thats no good, because you will get perfectly fine FPS as it is.

But if your going to OC for a bigger e-penis then thats cool:P

If you want to OC the FSB to 400, keep multiplier at stock until you reach your FSB destination, then up the multiplier. The temps really wont go up at all when OCing, until you up the vcore. When you up the voltage in an OC, you can get further because it allows the CPU to be more stable, but at the same time it also raises temps by maybe 5C.

[Washuu]

vcore is at 1.650, 12.5x166 speed.
my goal is 400fsb, should i leave the multiplier the same?, and i do want stability, so whats a suggested vcore setting?
plus i do want a bigger e-penis, my friend current has the same computer as mine, except hes getting a radeon 9800pro soon!
so, ill have to fight that ^.^

[Sgt.Igneri]

You keep the vcore at what it is now. As you OC, your gonna reach a point where prime95 or some stress test will fail quite often, thats when you up the vcore to the next level. If you want to up FSB, keep multiplier at 12.5 and OC FSB, but this will also raise the clock speed. If you JUST want to OC the FSB, and keep the 2.08ghz, lower the mulitplier and up the FSB.

[Washuu]

roger!

[Washuu]

okay, some setting or something is wrong...
when i tryed to OC, i just increased bus at first, from 333 to 400
yet... it failed to OC.
>.<
u can see my specs in my sig.. thats what i have, got any suggestions on what else i might need to do in my bios? winter is alrdy here, i get 93F idle temp alrdy, and i turned up my fan to full when i did try to OC so...

plus, when ever i try to oc the cpu, it gives me a "your computer has no keyboard" message
then i have to restart again, and then it gives me, "failed to oc" message

Lower the multiplier from 12.5 to 11 or so. Your CPU can't run at 200 X 12.5 = 2500 MHz. Try 200 X 11 = 2200 MHz

[Sgt.Igneri]

Yes the multi should be at stock for now- 11. And i hope you didnt OC from 333 to 400 in one OC...

[Washuu]

roflmao.... maybe.... ill go do that soon ^.^ then report back

[Washuu]

check my sig :D
http://service.futuremark.com/compare?2k3=1368703
some other proof too, all is good, thx!!

[Sgt.Igneri]

So what are the temps? How long did you run prime for?

[Washuu]

ran prime95, all of school, so 9 hours, NO ERRORS! and NO PROBLEMS! w00t
and idle temp of
CPU - 95F
MB - 68F
:afro:

[Sgt.Igneri]

Whats the load temps? Good job on the OC. Try and raise the multiplier now.

[Washuu]

CPU - 102F
---- i still havent done any lapping to the heatsink/fan plus i still havent added artic silver 3.... so yeppers, my dad just got home from a trip, and i still havent gotten authorty to buy AS3.... i goofed, and said thermal "grease" to him, and he said i alrdy had some and didnt need it, and i didnt get a chance to explain the rest of it... (ill just go thru the mother soon ^.^)

[Washuu]

ARRRRGGGHHH
windows is evil
one day, after awhile of having CPU overclocked fine, and i had done restarts of computer with no problems.

i turned on my computer and windows would fail to boot, motherboard gave me no errors

i had to set back all the overclock levels down.

i was mad, and walked away from the computer when it started up again, and left it too boot from RH9 linux ( i have to select either "dos" or "linux" on boot screen, or else it will just boot linux.

im too lazy to go back to windows, so now im using linux, which im patially blind to using.

if i ever try to OC again, should i put Vcore higher?

[Sgt.Igneri]

I told you, instability during an OC calls for a raise tot he vcore. Try upping it to the next level, get your old OC back, and run prime for 12hours.

[Washuu]

okay, raised vcore, ill report with prime95 tests, in a 1day and a half, *otherwise i wont have enough time with computer on*

my computer is in my bedroom, and just a tid bit too noisey to keep on when i sleep :-/ plus there is no other place in the house to put my computer.

[Cosmos]

I'm using 2500+ Barton. My plan is to reach 3200+ since I was told that it will OC to that safely. However...

In my BIOS setting, I do not see the FSB option. I do see CPU external frequencies and something is set to 11.0x. I did see FSB spectrum but I do not get option of incrementing.

Also, what is the desination point for FSB for 3200?

How do I find FSB:RAM ratio?

What are the side effects?

[Sgt.Igneri]

You must set all options in BIOS to "user defined" This will give you almost full control over everything.

200x11= 3200+

As stated in the guide, you must OC in increments not all at once.

The guide answers every question you just asked.

[Cosmos]

"To use the OCed CPU, you need to select "enabled" for one of the options in BIOS(cant remember name, just look to the right, itll show an explanation of each setting) Dont forget to chose a good FSB:RAM ratio that wont screw your RAM up."

Where doyou find FSB:RAM in the BIOS? Tell me the exact name for this ratio.

"Ok, so choose what you want to do. Up the multiplier and keep the FSB the same, or up the FSB, which will also up the clock speed without touching the multiplier. Basically, just OC with the FSB unless you want to keep the FSB at stock. "

I do plan to increment the FSB, but I do not seem to find the option EVEN after setting it to USER DEFINED. I do see FSB Spectrum, CPU External Frequencies, and the muliplier, which is set to 11.0x. Now, I have a slight feeling that FSB bump will occur in CPU external frequencies... But tell me where.

"Same thing, slowly apply the OC, instead of 20-50mhz increments, i would do 20mhz increments, or less, on an AMD. Blah, do the stress testing and monitor temps, etc etc. Once it gets unstable try upping the vcore to the next level."

About bumping up, are you talking about incrementing 20 mhz every system reboot? The part that I do not understand is where you said increment 20 mhz. Define incrementing please. Futhermore, how will I know it will be unstable or do the stress testing?

"Once at destination, peform a 12-24 hour stress test with no faults. If all gos well, move on to tweak the RAM(read P4 sec. for details) if it doesnt underclock in 5mhz increments till its ok."

Again, what is stress test?

[Sgt.Igneri]

What mobo are you runnning?

Upping the multiplier will result in an OC on the clock frequency. It will only up the 1.83ghz rating, notthe FSB. Upping the FSB will result in an OC of the FSB and the clock speed.

By incrementing, you are correct. 20mhz each boot. You must run a breif CPU stress test before moving on.

By stress test i mean a program that will stress your CPU, and check for faults in the OC. As stated, prime95 is probably #1 stress test.

[Cosmos]

Asus a7n8x-deluxe. Again, how do I up the FSB? Also, where do I get prime95? Do I run this program in OS or in BIOS?

[Sgt.Igneri]

Cosmos cmon man, anyone can answer these questions.

Google wouldbe a great place to start on where to DL prime95.

You run it in OS... obviously.

Do you have the latest mobo drivers and latest BIOS?

[Cosmos]

I do not have fsb settings for my bios. I use Asus a7n8x-deluxe. I think it is combined in CPU External Frequeny. I don't think 200 for 3200 is right because I'm already running on 166 mhz, which gives me 333 mhz fsb.

[Sgt.Igneri]

166x2=333mhz

200x2=400mhz.

3200+ runs at 2.2ghz clock speed and 400FSB.

AS I already asked, DO you have latest mobo drives AND latest BIOS?

[Cosmos]

Yes, sir! :bounce:

[Cosmos]

I know have 3200+. However, when I run Prime95, I get error on the hardware failure. The temperature is 42c and vcore is set to 1.700. What should I do?

[Sgt.Igneri]

What should you do? Obviously downclock it.

If there is an error, then its not a stable OC.

[moto]

lol way over my head..

[Washuu]

moto: then dont post here :D
igneri: i ran prime95 for 16 hours, no problems/errors
- and my temperatures are still the same as ever :afro:
- this will be good help to my friend, hes getting the same cpu heatsink/fan as me, and has same processor/mobo, so he can get correct cpu OC settings right away!
-thx for all the help!

Different hardware overclocks to different levels so your "correct" OC setting may or may not work for your friend.

[Sgt.Igneri]

Washuu hold up. NO OC is the same. Hell have to go through the same process that you did.

[Washuu]

funky... ha! more work for him

[BigD]

Just one quick question. I read the guide and others, over and over again but im a little scared to overclock, never done it before.

I am running P4- 2.4 GHZ on a 845PE max MSI board (533 fsb i think)
1024 ram (2700).

Im wondering how much I could up this too and how hard it would be for someone with no knowledge what soever...and if its very risky.

Cheers and thanks!:)
(I had a athlon xp2000 before, and it was running at like 70c all the time, for over a year LOL)

[Sgt.Igneri]

Nobody can tell you how far you can OC it. Every OC is different. Understand the guide as best you can, and talk to me if you have any more questions.

[BigD]

K thanks
Ill try it in a while maybe, theres not much need for me to OC now anyway its not like i have any performance problems with my current set up and a Radeon 9800 pro.

Just a thought though, a p4 2.4, could you get it up to 2.8-3.0 ghz under the right circumstanes? (good board, cooling etc.etc)

[Cosmos]

If you use water coolor or liquid nitrogen, then yeah.

i think 2.8 would be about your top-end if your use air cooling.

and mabey not even that...you wont know untill you try.

[Washuu]

another adrenaline rush for me soon :D
im all stable and purty at 11x200 vcore=1.7
my goal is 12.5x200 for a chip = 3200+
but, when the system wont boot from harddrive, and other stabilities, am i harming anything? and if it is in progress of "crashing" should immediatly restart, and change bios?
- should i wait to get some articsilver 3/cerminque/5 before going higher?

[Sgt.Igneri]

Got my 2.4c@3.3/1100 right now. 1.55 vcore. 2-2-2-5 timings on street racer GAT.

Sucks that one of the sticks i got in my package was bad, so im only using 512 right now.

EDIT: Ive decided to keep it at 3.12, maybe ill even lower it to 3.0. I had prime running for 16 hours at 3.12, no probs. There was some stability probs runnning 3.2 or higher.

Im sure the performance right now is close to a A64 3200+ because of so much mem. bandwith.

[Washuu]

okay, so i tryed to increase multiplier, system boots, but i get immediate errors from prime95..., so increase vcore, same thing again, should i increase vcore again?

[Sgt.Igneri]

Even if your temps dont increase much with the vcore, its putting more voltage on your CPU. If you give the CPU too much voltage, it can cause permanent damage. Thats a great OC you have for that setup. Im sure you wouldnt be able to get much more out of it on air.

[Washuu]

so i should go back to my original overclock?
right now vcore is at 1.7 and failed prime95. best to go back , eh?

[TheOtherDude]

Originally posted by Washuu

1.7V isn't very much. You should be fine increasing it to about 1.8V as long as your temps are reasonable.

[Hallucinogen]

I just finished running prime for about 8 hours, and it seems that my XP2500 is 100% stable at 2.5GHz!! god damn I'm so happy!!
This is by far the best overclocking chip ever, Sandra 2004 shows my CPU slightly faster then P4 3.4 GHz, I cannot believe this!!!!!
The vcore is at 1.85 @ 40C idle and 50C full load :cheers:

[Washuu]

i might try the higher vcore again, when it was as high as i said before, my temperature was still like only 35C/96F

[MultiVaC]

Hi guys, I've been having trouble overclocking my Athlon XP 2500+. The highest I can get it up to is 1.88ghz. I've managed to get it up 2.2 ghz and my computer starts up just fine, temperature stays around 50C. But when I run a game, about 5 minutes in the comp just restarts for no apparent reason. I've tried raising the multiplyer and the FSB seperately, same problem with both. I've got a gig of DDR ram, if that means anything. Any suggestions?

[Sgt.Igneri]

Have you tried upping the voltage?

What RAM are you running?

[MultiVaC]

The Vcore voltage is 1.68, I think that might be my problem. I'm going to try tweaking that a bit. I also checked my fan setting, it wasn't at full speed. I turned it up and the CPU is about 10C cooler. Thanks for the help.

[Sgt.Igneri]

Only up the voltage one setting at a time.

[kanette]

Quick question please.

My bios doesn't have a config for multiplier but it has config for fsb.
I am trying to oc, the first times, to my Barton 2500+ using ga-7vt600.

So where shall I change the multiplier at?

Please advice.

[kanette]

um and

I have a weird temp reporting here:

Bios > 57
Easytune4 > 57
Sandra > 39
MBM5 > 29, 29, 70

I don't know which program to believe in.

In order to change your multiplier you need to unlock your CPU, obvisouly your motherboard doesnt do it for you.
Motherboard like Asus A7N8X (all of them) unluck it for you, and make it alot easier for you to overclock.

Im running my GeForce 5200FX at 320/380... base is 250/280

[Sgt.Igneri]

Nice. Any artifacting?

[CokeLite]

nope... It will run at that setting for Ghost Recon, Splinter Cell, and Infantry but not for Raven Shield. It doesent want to load up the visuals for the game so when you go to start mission it will be fine for first few seconds then screen will freeze up, but its just for RS.

Another question. I have an Expertool proggie running in my lower right corner and it has a performance tab to where it looks like I can OC my Core clock and memory clock from there. Just got this computer about 4 months ago and ive never seen this before... have you heard of it?

[Sgt.Igneri]

Lower the settings, like now. Any artifacting and it can do serious damage to the card. Lower it to settings where you can run any game for 1 hour(at least) perfect.

[CokeLite]

Ok I did. It wasnt worth it anyway I can play RS w 30 FPS normal. Thanks

[Shuzer]

This is probably a stupid question, but.. can OCing a graphics card slowly kill it? Like, the performance starts to get worse and worse, until it sucks?

That's not happening to mine, or anything, but I'm kinda wondering, if a card goes, does it just.. go? And if it works, it works? Or can performance slow down over time?

[Washuu]

i believe only excessive heat and to much voltage can kill it, other then it just normal usage over a long time.

[spooky7000]

It will certinaly speed up the death process. You may find that one day your card is dead, and this day will probably come faster if you OC because of increased heat/voltage/resistance and all the other lecrical mumbo jumbo.

Life on the edge. :cheese:

[iamironsam]

Hey Sgt.Igneri, about that thread you just closed. That bit about the new Barton's being hardlocked isn't in your thread is it? Maybe you should include it or stop closing threads that you haven't read through.

[Sgt.Igneri]

It isnt, your right.

All OCing related questions should be posted here. Obviously if there is a thread dedicated to OCing stickied, Im not going to let people open their own threads about it when it should be here.

Next time PM that, BTW.

[vgard]

hey you almighty Sgt.Igneri, or anyone else for that matter..
I am currently running my barton 2500+ on 2800+ speed, and been running prime95 for over 6 hours. Is it nescessary to run it any longer? I mean, it's not that big difference(1.83-2.08)?
Stable as a rock this far though, and about 55Celcius..
I just upped the multiplier, not voltage or fsb..
I'm a complete newb, but your sticky has thaught me some tricks.. :)

[Sgt.Igneri]

Yeah, its rock solid.

Kick it up a notch now.

[vgard]

Soon baby, soon... :P
I just ordered a new heatsink and fan, my temp on full load is rather high!? Anyway, i need that new fan, since my brother want my old on his XP1600. :) should do the trick for him? hehe. It's a Spire Whisperrock IV. I ordered a Thermaltake Volcano 7+, is that a good fan for oc? Or should i order something else in the same range? i also ordered a couple of casefans for better airflow. I'm oc'ing my graphics card too.

About FSB.. My ram is kinda crappy. Haven't tried upping it yet, but it's a noname kinda ram. PC3200(i think the timings are set to 2.5,3,3,7 or something in my BIOS. Dont remember), so it should manage 200fsb? I'll try that later on. I really got the taste of OC when i ran Prime95. :)

[edit]
The volcano pushes Max. 83m³/hour (49CFM)
and spins 6000rpm at max.. :O

3000 RPM @24 dB(A)
4800 RPM @35 dB(A)
6000 RPM @47 dB(A)

haha! i just realized something.. :)
My psu is 250watt :O
I'm getting a new case and psu this christmas, perhaps i should stay back at the excessive oc till then? hehe

[The Terminator]

Ok. I have an AMD Athlon XP 2100+ at 1.7 GHz. My multiplier is locked at 13 I belive, Ill double check later. I have a max fsb of 160, its default is 133 and I upped it to 154 so my new GHz is 2.00. Now when windows loads I check my processor speed and it still says 1.7 GHz. WTF is that? can anyone help me out? and should I increase my vcore at all? Its at 1.750 right now.

[vgard]

Weird.. Where do you check the speed? System Properties?
On my comp it say XP3000 and 2.10 Ghz under it.
I clocked my Barton 2500 up to that speed.
My multiplier and FSB is unlocked.

Ya, I check it by right clicking my computer and clicking properties. I also check it in "System Information". It still says 1.73 GHz when in bios after I change the FSB from 133 to 154 it says 2.00 GHz. wtf is up?

[vgard]

It looks like your bios doesn't save the changes when you save(?) :P and exit..
What mobo do you have?

[The Terminator]

I got it to work but only could up it by like 5 mhz then it wouldnt save the changes or windows just wouldnt boot. Screw OCing for now Ill do it when I have a better comp.

[|SwE|FishStick]

***ALSO SET THE RAM:FSB RATIO LOWER BEFORE YOU START, KEEPING IT AT 1:1 CAN RESULT IN THE BEEP OF DEATH ***

Wtf does that meen??

[peterhoang2002]

couple of questions...
sorry if im stupid, but my bios options seem different from the ones discussed in guide

is the cpu clock ratio the multiplier? the options for it are 5, 5.5, 6...24

do i even touch the spread spectrum?

i have a cpu fsb clock select and a cpu host frequency select; do i just rais the fsb or the host frequency? i hear people OC'ing their fsb to like 160 and some numbers like that... how come my fsb options are only 100, 133, 166, 200 but my host frequency can be set anywhere from 100 to 233

which ddr:cpu ration is considered to be the lower one and how do these frequenies affect the comp?

my setup is...
2400+ stock settings: 15x133=2.0ghz(might be buying a 2500 soon)
kingston 512 2700 ram
stock hsf + fan (i have a new aeroflow next to the comp if its needed)
40C idle, 44C load with no OC
1 intake, 1 exhaust

[peterhoang2002]

wait a sec, so if i do get the 2500, i wont be over to over clock it to 3200 speeds and make the mobo recognize it as a 3200? or is there a way to unlock the multipliers on these?

[|SwE|FishStick]

Not if your steppings are 0339 and over (possibly 0342 if your lucky) which means that your CPU is locked. But you can still Clock it as much as you should be able to if it were unlocked. What you will have to do is to Raise the FSB from 166 to 200 (2500+ ---> 3200+). Almost every 2500+ Barton are able to be OCed to 3200+ but if you're unlucky, it may just reach 2800+ or something. And no, when the multpliers locked, the computer wont recognize your 2500+ as a 3200+, but who cares? the thing is that you've overclocked it, and that it is showned on Games, 3dmark, PCmark etc etc

[peterhoang2002]

is there a way to find out if its 0339 or below just by looking at the cpu

[peterhoang2002]

is it possible to OC the 2500 to 3200 by rasing the fsb to 200 (11x200) if i have kingston 512mb pc2700 333mhz (valueRAM)?

ok i found out where it says the week and year the proc was produced

ps. sorry about the double post. i cant seem to edit some of my posts

[Sgt.Igneri]

As long as you have a good HSF and raise the voltage to at least 1.675 you should be good. Try upping the vcore to 1.7, then checking temps. If there good then just OC it.

[peterhoang2002]

well i have a brand new aeroflow hsf thats sitting on top of my desk waiting for a new proc. my last question is are you sure the ram wont hold me back to just 333fsb becasue the ram speed is 333mhz? im so worried that i wont be able to OC past 333mhz because of my cheap ram

[Sgt.Igneri]

Well if you change the ratio to something lower. It will damn sure have trouble running OCed at 400mhz.

Oh and what are the tightest timings your able to get on the ram?

Sry i didnt realize that on the last post. Maybe it will hold you back.

[peterhoang2002]

umm... the only things i know about the timings of the ram is cl2.5. mobo has 100, 133, 166, and 200 fsb options and at 200 fsb, the DDR:CPU ratio options allowed by the mobo are 1.33X, 1.66X, 2.00X

correct me if im wrong or if it wont work but i should have no problem OC'ing if i get a good barton chip by setting the multiplier to 11 and fsb to 200 (11x200=2200) and the DDR:CPU ratio to 1.66X (200x1.66=332)

so according to what ive said, i would be OCing the proc to 2.2ghz yet still keep my ram at 333mhz?

theres no cpu currently in the comp so i cant check timings of ram, but i have the mobo manual in my hand and this is where im getting my other info

[munken]

How far can I clock my AMD BARTON 3200+ ?

[PvtRyan]

How far can I clock my AMD BARTON 3200+ ?

Totally depends on your cooling (boxed I presume) motherboard and memory (OEM and for example TWINMOS or Kingston makes a lot of difference)
But since the 3200+ already runs at a FSB of 200, I doubt your memory could take a lot more. But I'm no expert :)

[Sgt.Igneri]

How far can I clock my AMD BARTON 3200+ ?

List your full specs first... You cant just set it at any given setting, or it will be unstable. Maybe i can give an estimate, but you still have to OC in intervals.

[munken]

CPU /
Amd 3200+ (boxed)

Motherboard /
Not sure yet / but a good guess would be asus or soltek / nforce2

Ram /
1 GB Kingston HyperX
Ati Radeon 9800XT 256 mb

Harddrive /
2x 80 GB Sata (150) / manufactor not decided yet

well i would like to overclock my p4 2 ghz but i really dont understand from ur tutorial nor do i ever know how to get into my bios or check my motherboard

any help would be appriciated

[Sgt.Igneri]

Do you have a prebuilt comp, like a dell or something? If so then you wont be able to OC, and OCing ona dell or compaq or similar is out of the questions anyway.

[TheOtherDude]

well i would like to overclock my p4 2 ghz but i really dont understand from ur tutorial nor do i ever know how to get into my bios or check my motherboard

If you baught your computer pre-assembled from an OEM like Dell, you cannot overclock it. :(

If not, pressing the delete key as soon as your system gets power should get you into the BIOS. You may want to try pressing it over and over from the time you press the power button to the time the OS starts to load.

[LilBoy0626]

thx for the help both of you
sad to say it is a dell cuz my dad didnt trust me to build a computer although he is letting me build one when i gradjumitate :D

anyway another question
how do i overclock a radeon 9600 cuz i have no clue about that either

[TheOtherDude]

All you have to do is get one of the many good software programs to overclock ATI videocards. I perfer RadClocker (http://www28.brinkster.com/chrisww1942/).

[Sgt.Igneri]

When OCing the 9600:

Only OC the core clock, and NOT the memory. The memory on the vid depends on the ambient temp of the case, and that is certainly NOT a good temp on prebuilts(very, very poor airflow) The core is cooled from the HSF on the video card, so OC that, but still OC carefully.

[LilBoy0626]

so i overclock the core using radlink
how do i know when im overclocking the core and how do i test that it is still stable

oh yeah are there any other program you guys would reccommend because from reading about radlink it seems that i have to set up a profile for each game

[Sgt.Igneri]

I use rage3d tweak. Very simple. It adds a tab to your ATi control panel where you OC. When you OC, youll notice two slider tabs to OC on, the core clock and the memory clock. Leave the memory alone. OC the core clock at like 5mhz intervals, which means, you slide it up 5mhz, apply the settings, then test it.

To test, run 3dmark03 loops, for hours. When or if it starts to lock up, shut down 3dmark and lower the settings. Once it starts "artifacting" dont go any further.

[LilBoy0626]

Once it starts "artifacting" dont go any further.


what does that mean?????

oh and where can i get 3dmark2003????

[Sgt.Igneri]

Artifacting is 90% of the time this white snow that will appear around the screen. But in general, any kind of gfx flaw or if it crashes or anything, that means the card is unstable and needs to be lowered.

You can get 3dmark03 at www.futuremark.com

[LilBoy0626]

thx for everything man im gonna try to oc it in a couple of minutes :thumbs:
hope it doesnt fry "fingers crossed"
anyway how high do u think i can oc it, maybe to a 9600 pro???? or a 9700 np

[Brian Damage]

Getting an XP2400+... 2 questions:

1. How many variants?
2. How overclockable are they?

[LilBoy0626]

Sgt. Igneri everytime i try to move the core setting in rage3d tweak it just reverts back to default after i hit accept


any suggestions

[Sgt.Igneri]

Restart your computer.

[SubKamran]

I have some OCZ Enhanced Latency RAM (PC3200) and I can get the FSB to to 250 but only if the RAM is at 2.85v. I can't get above 250 because then it crashes in 3dMark01.

Any suggestions?

[Sgt.Igneri]

Whats the FSB:RAM ratio? Try upping the CPU voltage if you havent yet, and try tightening the RAM timings some mroe.

[SubKamran]

it's 5:4. CPU voltage may ruin my CPU, right? Also, my RAM is at 2.5-2-4-5.

[Sgt.Igneri]

What CPU do you have again? There is usually a certain limit which you shouldnt go over because it will damage it. But upping the vcore just to the next level usually doenst hurt it. Itll just raise temps. If you have an P4C i wouldnt go over 1.575, stock is 1.525 i think. If your temps arent great you should up itthough.

[SubKamran]

I have a 2.4C. CPU-Z says it's at 1.6v. I get a max of 45C on Prime95 on the maxium overheat torture test.

[Brian Damage]

Okay, my new computer's coming tomorrow...

I really would like to know... how overclockable is an AMD XP 2400+? I don't know what variant it is, but there are only a few, right?

i have a question
ive just now figured out how to oc my radeon 9600 with omega drivers and powerstrip
ive clocked my card from core 324 ram 202.5 to core 354 ram 212
ive run 3dmark2003 and i really havent seen artifacting or so i think
should i keep increasing both or just stick with what im at
mind you i havent installed any cooling just the factory dell stuff

nick

[ComradeBadger]

Um, keep OCing till you artifact! :D

(well, thats my way :) ) Anyway, I'm not responsible for any damage incurred ;)

Oh, and anyone know how to set FSB frequency using jumpers?

[LilBoy0626]

will it be really obvious when it begins to artifact?????
cuz im at 384 clock and 220 mem now and no signs of artifacting

[ComradeBadger]

Yes it is VERY obvious when it artifacts.

:)

[LilBoy0626]

so ur telling me to keep goin
how do i test for artifacting????? 3dmark2003???

[ComradeBadger]

Yeah, run 3dmark03, and you'll know when it artifacts. If that happens, press ESC, and clock it down boy.

Artifacts are black squares and things on the screen etc.

[LilBoy0626]

how much farther do u think i can go cuz im nearing the top soon

[ComradeBadger]

Um, I don't know :/ by the way, I have no idea what cooling you have or anything.. so it's possible if you push it too far without being careful, like in 5mhz steps, you could fry your card. So stay careful :)

[LilBoy0626]

is there anyway to check the temp of it

[ComradeBadger]

Nope.

Not without proper equipment/software, and I don't know any of it :/

[Sgt.Igneri]

If you cant keep your finger on the core of the card for over 5 sec without it seriously burning then its too hot.

[ComradeBadger]

Ok, thats a bit extreme, my softmodded 9800SE is really cool, and it's overclocked to hell :)

In fact if I go anyfurther, I get artifacts ;(

[Brian Damage]

Are artifacts caused by overheating or some kind of power drain?

And can someone please answer my XP 2400+ questions? Or tell me why they haven't been answered?

[The PC Nerd]

Artifcats can be caused by overclocking damage but most likely not by the overclocking itself.
-but i don't know jack shit about overclockign just about hardwaree in gen. so it may be possible because of memory skipping places and not knowing what to read so it prints out red or black spots
-it also could be from a power drain, not being able to retreive requested memory from the ram so it just says to itself "Self, we've waited here too long. We're screwing the memory request and returning a ff0000!

XP 2400+ Question...
I have no idea personnalyl visit an overclocking site and find the info, its out there.

______________-
I need a computer guy to get me into card overclocking and explain how they overclock a processor (is a packet sent to the card to change an option the controls the speed, etc) I already understand PC overclocking (very limited-ly)

[Brian Damage]

Um... yeah... artifacts are caused by overclocking, I know that... if you overclock a card too much, it gets artifacts... but if you scale the speed back again, they go away...

Anyway, the overclocking question is: How many varients of the XP 2400+ are there and how overclockable are they?

But you already said you knew Jack shit about overclocking...

EDIT: Oh. Can't be arsed, frankly. Just wanted to know from the smart people here... it wasn't urgent.

[ComradeBadger]

Yeah, I'm not entirely sure why they appear. It's not heat-related, heat just can cause damage. Artifacts do not mean pernament damage.

[Brian Damage]

I have heard that you can get rid of them by somehow increasing the voltage to certain components on your card, but that comes with extra heat...

[ComradeBadger]

My motherboard is strange, it OCs everything, the memory clock, the processor clock, the AGP clock. Thats why I'm scared to do it :o

[Brian Damage]

I don't think I'll do it straight away, but it'd be reassuring to know...

[ComradeBadger]

Read around, the overwhelming responce is yes, it's good for it.

:)

[Brian Damage]

Groovy! Do I need to get a new fan? I already seem to have a whacking great one stuck on there...

[LilBoy0626]

mr badger i have talked to u about this before but im just not sure about this
i have a 9600 np and i have overclocked it to core 391 mem 222 from its defaults at 324 core 202 mem
i have in no way shape or form seen artifacts so should i keep going...i mean ill be hitting 400 core soon????

[Unfocused]

OK, so I have this problem: I've got an Intel D845PESV motherboard. The BIOS doesn't have any OC options, so I wanted to OC my Celeron with a program such as CPUIdle, SoftFSB etc., but they don't support my motherboard. So what are my options (if any). :|

[Maxi]

Buy a new mobo if you want to oc.

[Meteor_of_War]

Havent read through this thread since it was on like page three so i figured i'd just throw this out at you guys and see what you think...

I've recently overclocked my 9800 Pro (Rage3d tweak) and AthlonXP 3000+ (upped the multiplier) and now i want to try overclocking by the FSB. Only problem is my RAM isnt exactly top notch. I have 2x512mb of Corsair 'Value Select' pc3200 DDR RAM @ 400MHz. How far do you think i could expect to push it?

current specs:

AthlonXP 3000+ 400MHz FSB @ 2.3GHz x11.5 multiplier
Asus A7N8X rev2 bios ver.1006
2x512mb Corsair Value Select pc3200 DDR RAM @ 400MHz 2.5-3-3-8
9800 Pro @ 430/371 w/VGA Silencer

[Sgt.Igneri]

Im thinking maybe 415 on stock vdimm, maybe 420 or a bit higher with an upped vdimm. You acn always set a different CPU:RAM ratio when you reach its limit though and keep going on the CPU if possible.

[Meteor_of_War]

Set a different CPU:RAM ratio??

I thought it was always best to run AMD chip's FSB in sync with the RAM?

[TheOtherDude]

Set a different CPU:RAM ratio??

It is.

Well, not necessarily AMD chips, but you do want to keep the Nforce2 chipset in sync with the ram.

[LilBoy0626]

man this thread is dying
well i gots a question
i have a pentium 4 2ghz on the northwood core
the fsb is set at 100 and the multiplyer is at 20
Im on a Intel D845EPT2 mother board (Its a Dell cuz my dad ordered it)
In the bios there is no option for fsb or anything to do with the processor

How do i overclock???? :cheers:

[Maxi]

Can't. :(

[LilBoy0626]

man that blows dick

:sniper: DELL

[Alig]

Ok as i have no clue where to start with overclocking safely/properly perhaps someone can answer a few questions...

Whats this i hear about unlocking/bridging your cpu? is that hard to do and requires manual labour?

Im running a KV7400mb fsb mobo with an AMD (Throughbread 333mb fsb) 2.6+ with 1024mb DDR400 and its at 45c now, i think it goes to about 50c - 55c when i've been playing FC for a while. I've messed about with it but whenever i do/have games crash, UT2004 just crashes to desktop and so does FC so is there anyone here who thinks they can help in any way at all? :smoking:

Whats the best cooling solution with Air? Sound is not an obstacle, i use headphones.

[ratledge]

Sorry - nube as they come here! :laugh:

I just got the system described below yesterday, so I don't plan to sleep this weekend! :cheese: With an ASUS P4P800 and OCZ 500 "EL" Gold, I've been told I should be able to OC to 560-580 depending on how I hold my mouth and whether I got the lucky pair or not. That would make my 3Ghz into a 4GHz or better, and the ASUS 9600XT/TVD is already rockin'...

Please don't beat me - I've never really tried to push a P4, before - anything you do would help, 'cept p'ing on my parade! };^)

I've got an Enermax 550 "Whisper" PS and an OCZ "Eliminator 2" heat-sink fan combo with fancy thermal paste and all that jazz...

The RAM is rated 2.5/3/4/7, but I know I'll likely have to tame that a bit!

[asdasd12345]

I have a Athlon 2400,
512MB DDR333
20 GB HD
Geforce 3ti200 64mb

i want to get a new video card. i can spend 200 or below. please advise me on which one to get.

1) radeon 9600xt with HL2 coupon
2) radeon 9800 Pro 128mb Sapphire
3) Radeon 9600 pro for around $100

thanks

[Asus]

It depends what quality you want to play HL2 and future games at.
I personally would go for the 9800Pro.
You will not beable to play HL2 or future games at the same res, FPS or detail level if you go with a 9600 XT/Pro vs the 9800Pro.

[Daegon]

In my personal experinces, which are quite broad, i've found that your best bets insofar as video cards go, are the 9700 and 9800 series. A used 9700 pro can be found on ebay for about 100, and for most people, that is going to be quite sufficient for playing anything in the near future. It's a DX9 card, so compatability is not an issue, and it is really quite quick, especially with a little OC, especially on the ram.
So in conclusion, if you feel a tad limited in the monetary department, look into the 9700pro or 9800 non pro series. I'd shy away from anything that says SE, becuase those are the crippled versions of otherwise amazing cards. However, if you've got the money to spare, or are willing to wait a little while, please consider buying a card from the new series that nVidia and ATI are currently releasing and will continue to do so in upcomming months (X800, 6800) These are truly amazing cards and you will see ~ a 100% increase in gaming speeds, even with maximum quality.

Dang that was long.

Unlocking the cpu:
This is the practice of bridging (connecting) connections on your cpu that would have otherwise been cut, thereby allowing the user to set (usually through bios) other multiplier settings (FSB x Multi = CPU mhz) by doing so you are allowed much more leeway in changing the cpu speed.

Crashing a cpu mishagos:
firstly and foremost, your AMD XP2600+ does not operate at 2.6 ghz, its a PR term to compare the performance of AMD cpus to those of intel. Essencially it's saying that a 2600 will perform as well as a 2.6ghz p4. For the most part that is an appropriate comparison.

now that that's out of the way, your crashing problem is most likely due to system instability. that can be brought on by many things, on the top are RAM (use a program called memtest to check how well your memory is performing while oc'd) and too little voltage to the cpu.

Your temperatures seem alright, but that's a pretty big rise in idle-load temps. Try looking into picking up an aftermarket heatsink fan. Some of my favorites are the thermalright all copper lineup and Vantec's Aeroflow. I'd shy away from the majority of the pretty looking ones (ie ThermalTake) because,for the most part, they look much better then they perform.

You might be interested in taking a look at this link http://www.overclockers.com/articles373/socketA.asp
it contains a list and direct comparison of many of the HSFs that are on the market. (The lower c/w the better)

if you've got any other questions, or want clarification on any of this, feel free to pm me, or just post here, I might find it.

BTW ratledge: try 2/2/2/11 most ram (read: even generic) can hit that, and that long latency at the end can allow for a bit more speed where it counts.
edit: Sorry for the double post there.

[Sedako]

Just a few questions, but first i'll provide my specs:

Mobo - Asus P4SD-LA
Processor - P4 3GHz HT w/ 800MHz FSB
RAM - 512 MB DDR/SDRAM
Video Card - Radeon 9800

First, I need to know how to access the correct page in order to OC. When I go into the BIOS settings, there are no options to select user defined settings or change the multiplier or FSB.

I also need to know which value to change when OCing my video card using RAGE 3D Tweak (Core clock or Memory clock or both.)

Is there any way I can check my system temperature from windows? I am using prime95 as a stress test.

Thanks for any input.

It's a Powercolor 9800SE. I'm on a tight budget, and I know it's risky softmodding but seeing as this one is 256-bit, it should work. Should it work because it's 256-bit? It's either this, 9600xt, or 9700 pro refurb.

[RTFMish]

I would suggest looking at Radeon 9800 128bit memory interface, it's not as good as the 256 but I am pretty sure it is better then a 9800se because of the pipelines.

[Daegon]

is there a 9800 with 128bit memory? I have never seen one. Ever. The answer to your problem is the newegg refub section.

It truly is a godsend. I just picked up a 9800pro (first series black pcb) for something like 170.

oh, and I have attempted to softmod 4 9800se's (256bit L shaped ram) and all have failed in one way or another.

The 9700pro is a solid performer. It's my suggestion.

[RTFMish]

I don't have to mess with jumpers if I overclock like the guy in the first post of this thread said to right?

[Maxi]

Depends, what motherboard do you have?

[SidewinderX]

well, jumper are ones of the easit things to mess with :)

usally you jsut have to pop them off, and then back on if you've really screwed soemthing up.

is there a 9800 with 128bit memory? I have never seen one. Ever.
Yes there is. Shappire has made one.

[RTFMish]

Depends, what motherboard do you have?

If your talking to me, I will have a ABIT NF7

[Maxi]

That's a VERY oc'able board iirc. You only have to mess about in the bios. Go here www.ocforums.com and read the ocing faqs, plenty of good info.

[SidewinderX]

that's the exact motherboard I have, so if you have any questions, feel free to pm me or contact me on aim.

[RTFMish]

Ok, just wondering, was talking to my dad about overclocking and he talked about old school days when he had to mess with jumpers, and every once in awhile he blew the motherboard and stinky smoke came up.. Scared me because this will be my first OC ;/

[Daegon]

what are you wondering about? but yeah, jumpers (k6, P1 era) actually changing the crystal that generates the clock (286 era) and burning silicon (everlasting) have been around for a while.)

Maxi: OCFORUMS UNITE!!!

[CaT^_^]

1 question, how do you change the RAM timings in BIOS cause i don't have any RAM timing option in BIOS. My ram is at 385 now and I'm afraid that it would blow on me

[Asus]

In the old days, the bios was rather simple. All of the CPU options were on the board in the form of jumpers. Usually a small patch of jumpers on the board for Multiplyer etc. My old Asus board is like that.
You always had to refer to the manual to see which jumper you needed to change.

1 question, how do you change the RAM timings in BIOS cause i don't have any RAM timing option in BIOS. My ram is at 385 now and I'm afraid that it would blow on me
You mean 192. ;)
Sometimes they list the timings as RAs to Cas and labels like that. Quite often you have to set memory options to manual before you notice where they are. Look for a string of numbers. E.G. 2.5-3-3-6

If you go to high or lower the timings too low, it will simply not boot and you will have to reset the cmos jumper. There is only a slight chance the memory will quite working on you unless you increase the RAM(DDR) Voltage too much.

[Gajdycz]

if i over clock my cpu, will that damage my mobo if it burns out?

[Asus]

if i over clock my cpu, will that damage my mobo if it burns out?
There is a chance...although that mainly happens when you increase the Voltage too much.
Which is why I only OC as much as I can on stock voltage.

[blackeye]

increasing voltages can have a huge effect on the temperature of the case.

[crownest]

Theres one thing i find that its kinda unfair, i have a FX 5700 Ultra, i put it on Auto Overclocking it sets to the best safest clock speed. However i dont see any improvement but sometimes worse performance (but GPU temp doesnt increase), same when i download new drivers.

WTF is this happening?

[smsKONG]

My system:-

AMD XP2000+
MS-6382 rev 2.0 FSB 266MHz (2x133) AGPx4 USB 1.1
768MB samsung pc2100 DDR RAM (2x133)
128MB XFX5900XT
450W PSU

Anyway my mobo is rubbish and doesn't support OCing, hell I've read the manual and apparently it doesn't even support my CPU. It supposedly only supports upto 1.5GHz!! Sandra tells me it goes upto 2.0GHz?? can anyone help on this one please?
So I can't OC but if it does support 2.0GHz is there any real point in upgrading to a 2400+ (and obviously I know there is a point cos it'll run faster! But how much really? much or not much?) (by the way I already know the answer-buy a new mobo, right, but I,m broke and cant afford a new system but might be able to convince someone to buy me a new processor!)

I know, I know- this is an OCing thread and they're upgrading questions but what I really wanna know is how overclockable is my GPU? Has anyone already overclocked an FX5900XT so I can save myself a week or two of fidddling and benchmarking over and over again.....?

[Fletch]

I think the current weakness in your system would be your processor, even though im sure you'd be able to play HL2 without any problems at (or close) to the high settings.

I wouldn't recomend overclocking your graphics card as the risks involved don't really justify the small performance increase possible from overclocking a 5900. I read in an issue of CustomPC that some of the cards having been overclocked by 25% produced a 2% increase in performance. However this may have been down to inefficient drivers at the time (october 2003). Im sorry i can't be much help because im more used to ATi hardware.

Also if your CPU is bottlenecking your graphics, then an overclock would give no improvement in performance.

[smsKONG]

Cheers dude, been doing some research on the subject myself, and from what I've seen I should be able to pump my GPU upto the perfomance level of a fx5950- sounds good, but in reality it's naff all, so...

Also found out my mobo can take a 2GHz CPU (job and a half tracking down the info I needed :flame:!! ). So I might pop an XP2400+ in to get me upto that recommended processor level for HL2, can pick one up for £50 so its not too much (especially if I can blag someone else into paying for it :P )

[Fletch]

No problem :cheers:

[AzzMan]

Hey just a quick Q, how well do the Mobile A64 2800+ (1.6ghz) and 3000+(1.8ghz) overclock? I'm just wondering if it is feasible to get one up to 3400+ speeds on air.

edit: with a good h/s of course

[Asus]

You would have to check if the board is actually compatible first.
Most desktop A64 boards do not support A64 mobile CPUs. Only a few have the bios support.

My regular A64 3000+ 2GHz (10x200) CPU clocks to 2.4GHz easy on air with stock cooling. Default voltage too. It's the new CG stepping though. If I had got the older C0 stepping then I wouldn't have got this far at all. hehe

[AzzMan]

Oops my bad, I thought I heard somewhere that the mobile athlons would work on desktop mobos. Thing that I like about those was that 1mb cache, which I heard adds a good amount of performance. Oh well I guess I could just get the clawhammer 3200 and OC that...

edit: nevermind i found what i was looking for...

[Asus]

Yeah, there were some boards that will work like the some of the desktop Asus boards etc.
The chaintech board I believe will work but there is some effort in getting it to work right.

[shadow6899]

i got an amd athlon/xp 2600+ at 2ghz help me get it higher!! also an asus a7n8x deluxe motherboard at 333 mhz fsb, and a 9800 pro

Do you know if your board is a version 1 or 2?
It will say in white letters inbetween the white PCI expansion slots.
Probably "rev. 1.01" or "rev. 2", something like that.

[shadow6899]

ehhh im not sure dont see any numbers, if u mean if it's an nforce1 or 2 it's 2

[Fletch]

I take it that your processor's multiplier is 12/12.5, and so i'd reccomend lowering it and increasing you'r FSB. You'r clock speed could be the same - eg 10 multiplier and 200Mhz (10*200 = 2000 = 2Ghz) Fsb but it would provide bigger bandwidth and increased performance.

Increase the FSB in moderate steps though, and use stress testing tools to check stability prime95 (http://www.mersenne.org/freesoft.htm) is reccomended. Make sure your ram is capable as well, that is it's rated PC3200 (200Mhz)

[ĐynastҰ]

hey guys. to completely change the subject: is the connect3D 9800 pro 128mb worth O/Cing? is it a good O/C? im a noob at O/Cing so any help would be great. ive just downloaded rage3d tweak v3.9, and know to increase core and memory seperately in 5-10 each time. ill run 3dmark03 each time untill artifacts appear etc.

thanks again.

No one knows for sure if it's a stock card and doesn't have special memory.
They are all chips from ATI and how good they are is random.
GL

If you have any thermal compound laying around you could take off the heatsink and check out what core it is (R350 or R360). Then take the time to put on some grease. R350 are more hit and miss but the R360 is a 9800XT core which should be a very good OCer.

kk ill check that before i turn my card into a slightly burnt paper weight...and one thing to ask regarding the O/C question above for the cpu: where the hell do you alter the fsb on the a7n8x-e deluxe mobo??!! i can only change multiplier and voltage...im getting so pissed off as i know i can change my 2600+ to a 3200+, as the mobo i got is great for gaming and o/cing (or so im told by many people...)

If the jumper on the board is set right, then you should be able to change the settings to manual from Auto and increase the FSB.

[ĐynastҰ]

yeah but my point is: there literally is NO fsb in the bios, and i cant even find it greyed out as it would be if the settings were on auto, thus being able to be changed when switch into manual mode.

Isn't that it?

[ĐynastҰ]

that's the one but u can only change it to 133, 166 and 200. unlike my other mobo where i could change it by 1 each time.

haha even the review says the board is a bitch to OC

[Asus]

What happens when you just hit enter? Doesn't it allow you to increase in steps of 1MHz?
I think on my old A7N8X DX board if you just hit up or down it choose between the selections but I could hit enter and a pop-up menu allowed me to select the exact speed.
Maybe it's different with these new boards.

If you wanted to OC to 3200+ speeds than it would be 11x200 anyway.
Multiplyer locked on your CPU?

[ĐynastҰ]

i get options for 100, 133, 166 and 200mhz. each one i select has an affect on the ram cas latnecy etc, either increasing or decreasing each accordingly, but thats about it. the multiplyer isnt locked, so that can be changed along with the cpu voltage.

[ĐynastҰ]

a walk through on exactly how to go about any useful changes would be appreciated as i am a complete noob when it comes to O/C in bios :(

I was just wondering. The motherboard Mentions agp voltage and gives me an option to increase it. If I plan on overclocking a video card would this allow me to reach higher clock speeds and what temperature would I expect. I dont have a 6800GT but im just wondering if increasing AGP voltage would allow me to clock higher.

[The Terminator]

increasin the AGP voltage? You mean bus speed? or actually increasin the gpus voltage?

[blackeye]

Nope you can increase it to 1.85 volts from 1.55 or you can keep it on auto.

[Asus]

You wouldn't want to increase the AGP bus, that would make it less stable.
The only time I could see you wanting to increase that option is if you were OCing your system bus without a PCI/AGP lock. So you could have to increase it to remain stable.

That won't make a difference OCing your video card at all. Infact I wouldn't increase voltages at all if you can't help it or don't know what they do exactly. hehe

[Dead-Inside]

If you're going to overclock a Sapphire Radeon, don't worry it can handle it. You can get at least 10% without worrying if you have a chassiefan.

[muka3d]

I overclocked my P4 2.80C to 3.0GHz, and she's running fine, and cool!

[Illegal Amigo]

I want to overclock my 9800PRO to xt speeds, but I'm nervous of doing so. If I get artifacts, are they forever? Or can I bump the core/mem down and they go away? I'm scared of burning out my card. (I have a Vantec pci fan card that also cools my video card).

The only way you'll hurt your card is if you OC by a lot at a time. If you slowly increase your speeds by small increments, like 5mhz, you should be fine. If you run into artifacts, lower your speeds by 10 mhz or so until you don't get artifacts anymore, and then as a precaution, go down another 10 to be safe.

Hi all. I have been trying to overclock my 2600+ processor into something a little more meaty, but so far I haven't had any success. I think i've located the proper bios settings...

I see two options that are grayed out. CPU multiplier and something else. When I set 'CPU Speed' to manual, they become active. The multiplier is set to 12.5 and the something else says 166/33.

Now I have tried increasing the multiplier to 13.5, but when I restart the system nothing happens (no post). I turn off and on again and it takes me back to the bios with the message 'System hung because of improper frequency settings' or something like that. I have also tried adjusting the other setting with the same results.

What am I doing wrong? I can be more specific on the setting labels and the error message if I have to...

Increase the multiplies in much smaller itterations if possible, 0.5 is reccomended. As you progress you'll eventually have to increase the Vcore to keep the system stable, with the drawback of more heat etc.

*sigh* No luck.

Stock settings are:

CPU Frequency Multiple: 12.5
CPU External Frequency: 166Mhz
CPU VCore: 1.65v

I'm not supposed to mess with anything else, am I? I tried increasing the multiplier to 13 (up by 0.5). It hung. I tried increasing the External Frequency to 200. It hung. I tried both of the above (seperately) with a voltage increase to 1.65v. It hung! Nothing works. Should I give up on overclocking?

for you people who are afraid of accidently destroying your gfx-cards when trying to OC them.
sapphire has some cards that wont void the warranty if you oc them, they even encourage you to OC them because with the card they send some apps for Ocing.. if you want the name of the cards just send me a pm or something.. but its probably faster for you to google for them or something cause im on a modem so im not online much.. rawrr out.

i just overclocked my radeon 9100 from 250.0 core/200.0 mem to 265.50/221.63 using the ati tool, i used the find max core and find max mem and this is what it oced to, i have had no problems with artifacts and i am wondering if it can be oced even higher without the use of fans or such. this is all jsut a practice till i get my msi 9800 pro thanks

You can go higher, just be careful :)
