Stable at 4Ghz before, but not anymore???? Please help.

post #1 of 23
Thread Starter 
Linx is now giving me errors, where it hadn't before:

Now(1.28Vcore, 1.28 QPI/DRAM, 1.64 DRAM bus):




Before, 2-3 months ago (1.265Vcore, 1.265 QPI/DRAM, 1.64 DRAM bus):



I haven't changed any bios settings (other than bump up the voltage a tiny bit since it's failing in Linx) since my original tests. Why is my system suddenly becoming unstable?

sometimes updates can do this to your CPU, you just need to adjust the voltage and find stability again.

mine started at around 1.375 Vcore and now it is down to 1.3625 for no reason it seems. Just something that happens, i first noticed it after doing an update for windows then just lowered the Vcore a bit and all was better.

Seriously, software updates can actually do that? I thought it largely wouldn't matter, as it's being stressed at full load anyway

well i didnt do anything else to my computer other than windows update, so yes, it seems that can happen. BTW, you should start up FRAPS or some other FPS monitoring program and play some games when you think that the OC is stable. When you do this make sure that the FPS is somewhere where it should be.

for example, when i play SC2 with what i think is a stable OC (IBT for 200 runs with no errors) i would start the game and be getting 50ish FPS which shows that the OC is unstable. So i go back into the BIOS and tweak the vcore a bit and then i am up to 85FPS in no time, meaning it is perfectly stable. So play your favorite game when the stability tester says it is stable to be sure.

I ran memtest before as well, and it seemed stable. The only difference between then and now is that BCLK went from 191-192 and ram went from 1535-1539). I doubt it's because of that, as things seemed fine for a few months, until now.

Before (2-3 months ago):

im saying try tweaking the vcore, that will solve this, i had the same problem before.

No, run memtest now. You could have a stick that's failing and that's why it's not passing LinX. You probably will never encounter a BSoD or anything because using 12GB the chances of accessing that part of the memory is slim.
