Can i ask for youre bios settings i'm currently on place 15 whit the x4 860 whit 4,5 ghz ( currently running 4,8 ghz to ) but how you got that low voltage ?

Awesome CPU man, I think I might need to try one!

What temp is cold bug and cold boot?

the voltage is not the real voltage . if i remember weel i was around 1.7v

for the cbug it's around -90 and cboot is around -50
