I'm trying to increase the OC on my c0 i7 920, and so far I'm having stability issues at 3.8Ghz (1.3V Vcore, using IntelBurntest, stress levels high through maximum fail on the second pass(2048-10755MB) while standard (1024) succeeds. I ran Prime95 for about an hour, no errors (I've had an acquaintance recommend P95, I'm a fan of IntelBurnTest).

That's just for 3.8Ghz. I've gotten to 4.04Ghz at 1.35Vcore min, bumped it to 1.44Vcore to try and get it to not freeze upon running P95/IBT. I stopped because it wasn't doing anything and I started feeling scared. System seems a tick less snappy upon startup than it did before, it's probably something else. Not that it matters since I'm generally not awake upon startup.


General system info/current bios settings
Board: P6T deluxe V1
CPU: i7 920 C0 Stepping
RAM: 12Gb G.skill 1333
Cooling: Cogage True Spirit
Temps: Ambient first session: 22C, the 3.8Ghz OC maxed out at an average 76C.
Second Session: Similar Ambient, maybe 1-2C cooler, 3.8Ghz OC maxes at ~74C.
Bios Settings​
HyperThreading: ON

I normally run at 175x20 with everything else on auto. Voltage is around 1.272 via cpuz.
