Linx stable for 2+hrs, prime failing within 30 seconds

post #1 of 14
Thread Starter 
So, I have kind of a big problem.

First of all, my rig is


i7-2600k
Asus P8P67 3.1
2x 4gb Corsair 1600mhz 8-8-8-24 @ 9-9-9-24
Thermalright Archon

That's my issue: I can ran 2hr+ of linx @ 45x 1,304-1,312v (68c max t), but prime 95 @ 6500mb (1344-4096 range) will fail in 30 seconds. I'm talking about SECONDS.

I tried pretty much everything. Nothing like raising the VCCIO (all the way up to 1,2v), lowering/raising the cpu pll voltage, increasing ram voltage, increasing VCCSA voltage, lowering DDR3 speed (down to 800mhz as well) actually worked.

Nothing works but raising vcore.

The sticks aren't faulty: i tested them with memtest 86...no errors at all.

Power limits are set to
255
255
250.000 (current control limit)

C1 enabled c3, c6 disabled
LLC is set to high...but lowering/raising it doesn't do the job.

Phase control is set to extreme

Vrm frequency 370

Internal cpu pll is OFF (enabling it didn't help).


I always get bsod 124. Never an error, just instant bsod.

What else can I try to do?

For prime stability I actually need 1,344volt (while priming)...which is 0,040 more then the voltage required by linx!! It doesn't make any sense!

Please help!

Thank you guys!

bsod 124= increase/decrease vcore or QPI/Vtt

I would guess it needs more vcore to become stable. Ive always run prime for the final stability test, and had good results. 2 hrs in linux isnt much to get a truly stable chip imo. I'ld raise the vcore some and re test prime until you get some longer runs in prime

Yes, raising vcore works.

The point is: how can I be stable for 2 hrs with linx (sp1 installed), and getting bsod 124 in 10/15 seconds with prime?? 2hrs stability vs 10 seconds stability at the same vcore!?

Different algorithms stress different components.


A Linear Alegbra test is different from a Calculus I test.... even if they are both math tests and stress students. thumb.gif

But why is this only happening to me? frown.gif The whole world is stable with linx...am i just unlucky? Or is it prime so much heavier than linx?

I run linux at first to kinda get a base line for settings while overclocking. Once i get 1-2 hrs stable on linux at my desired freq., then i run prime and get it stable there, which usually requires raising vcore and a little tweaking.

Prime95 didn't consume anywhere near as much power as LinX. ~120w vs. ~150w.

Could cause voltage weirdness if your VRMs aren't behaving appropriately. Lower your VRM Frequency to 350, and try changing phase control to default.

Can I ask why you're setting P95 to stress 6500MB or RAM when you only have 4GB? headscratch.gif
