Core i7 920 rev D0 stepping 5 :)

[Dahmer]

I guess I got one of the worst batches
4.0 GHz needs over 1.3 V, bios setting 1.4 and cpu-z reports 1.36 V when stressed. I tried lowering but when I do occt crashes after a few minutes. (no bsod though)

Changed BIOS Settings :
bclk = 200
most of the cpu settings off including turbo (ht still on)
vcore = 1.4 V
qpi/vtt = 1.4 (found some guide that suggested 1.5 but lowered it to 1.4 and it's doing fine, could probably go bit lower still?)
ram multi = 8x (results in 1600 MHz) using 1600 OCZ Reaper
uncore multi = 17x
rest of the voltages are set to auto

Any ideas here?
