Cause of these Prime95 Errors?

[fundamentaltheorem]

Hi, I'm running into some errors that I'm hoping you can help me sort out.

I'm running an E8400 C0 @ 3.6 GHz on an EVGA 750i FTW. RAM is 4GB OCZ Titanium 4-4-4-15 @ 2.2v.
Vcore is set at 1.30 in BIOS, reading at 1.28 in CPUID HWM
FSB 1600QDR - 1.2v
SPP - 1.4v
NF200 - 1.2v
LDT - 5x

I'm not getting and random crashes and games run without any issues, but I never really did much stress-testing. Errors I'm getting:

Less than an hour of Small FFTs - Worker 1: FATAL ERROR: Final result was B9CA653A, expected: 0555250D.
Less than an hour of Large FFTs - Worker 2: FATAL ERROR: Rounding was 0.4765625, expected less than 0.4

Are these voltage related? With Vcore a bit lower I used to get the Rounding error at 0.5.

The reason I ask is I'd like to try to go to 3.8 GHz, but before I even try I'd like to pinpoint where the problem lies.

I can give you more BIOS settings if needed - Thanks for your help!

Typically, that means that the vcore is too low, but only by a very small margin. The first thing I would try is upping the core voltage by a hair. There are a couple of other things you could mess with as well, but in all likelihood, the core voltage will fix it.

^ this.

if you fail a test, its because your OC isn't stable. but if you aren't crashing, a Vcore boost should be enough to stabilize it.

Intel's recommended maximum voltage is 1.3625 volts. So you have plenty of room to play with.

Had the similar problem where i upped the volts for Dimms and was good to go.
