Turns out my board doesn't like x12 uncore, even with x6 RAM...
This might be promising!
Now for a short stability test... Currently running 1.425 vcore in BIOS, says 1.4 in BIOS health status, also in CPU-Z
Upped QPI to 1.3 and RAM to 1.6. 37C idle with the fans on full. Not too shabby.
EDIT: Turned Turbo off since it locked up and BSOD'd right when I clicked Prime95 start:
This is going a lot better really! I'm even still just under 70C stressed like this
EDIT 2: BSOD after about 30 mins of Prime. I might get that 4Ghz stable on 1.5v, but that's gonna mean near 75C temps. I dun want that.
So, I clocked back to 3.66, see if I can get that stable.
