Testing overclock stability with x9000

Hi guys its me again
Im running my x9000 es at 1,437v for 3,8ghz. This value has been pulled from cpugenie64 stress test tool, but something isnt adding up.

If i try to raise the voltage and multiplier, lets say, 20x for 4ghz, it just bsods the hell out of it.

Something is telling me that im missing something. There are alot of peoples that run their x9000 (even ES like mine) at more lower voltage amd theyre able to hit 4ghz.

So my question: what should i use to correctly check the right voltage? Someone adviced prime95 for more than 5 minutes is ok.

Any help is greatly appreciated!
Thanks

 

I gotta be honest with you.

No one will have their X9000 run at 4.0GHz stable for long hours and for everyday usage. It runs at this speed for benchmarking. And remember that benchmarking is a temporary test. It will have to be returned to its stable speed after a while. Mine runs @ 3.8GHz 24/7 which is my highest and most stable.

My X9000 is NOT stable at 4.0GHz and will have errors after 30 minutes of use. But stable at 3DMark06 and Vantage use. Stability is very important to keep the processor running and the account of its lifespan as I am using for other purposes which requires alot of CPU power.

And also, I shall assume you run 4GHz @ 1.5000v? Depending on every X9000, not all of them can work at a certain voltage.

3.8GHz is your current stable (so as mine) and that's good. Most users run at that speed or lower. So far even the X9100 users on other machines have never made 4.0GHz stable -for long hours- as well.

I've seen your 3DMark06 scores and they're good for twin 8800s. Now you should try gaming to check for further stability.

 

Exactly what i thought.
Stress testing the cpu @ 4ghz gives me a bsod, never tried a benchmark thought, prolly the fact that is not using the cpu at fullpower doesnt make it crash, but in games it will.

So far my es behaves exactly as you said: at 1,5v its stable for 30secs then bsod. No issue running it at 3,8 with current voltage: playing new vegas keeps my cpu around 62c with fullfan on.

Well for 300$ i guess i cant complain compared to OEM version,which requires less voltage. Thank you Some!

Btw im using win7 x64 but im reading of peoples with better performance using xp x64. Should i switch to it for gaming, loosing dx10 enabled features, or isnt worth the few fps gain?

 

I run mine at 3.8Ghz at 1.3625v. I agree that 4GHz is not stable, or the CPU gets too hot. I can of course get my stable at around 1.45v but it runs too hot for my liking so I settle with 3.8Ghz.

 

Its good to see how ES cpus compares to OEM. Althought my voltages are much higher than yours Mag, i still have the same temp under full load,maybe a few degrees more. So far i peaked 73c while gaming @3,8 1,4375v.

 

Yes around 73 degrees is fine, I see these can go up to 90c if benchmarked real hard, that is at 4GHz though. By the way what stepping and revision do you have on your ES?

 

Yeah, my x9000 its a C0 stepping. My x9100 is E0

 

Mine is stepping 6 and revision C0.
