Right now I have my CPU COed at 4.3ghz at stock voltage. When I try to go 4.4ghz it always crashes/freezes/BSoD. I tried increasing the voltage even up to 1.4v and it still crashes and stuff. I have all the power savings off. Is my power supply inadequate?
The only thing that should be holding the chip back from a solid 4.5 is the MB. Try upping the voltage a bit more, and see where you can get.
Ya, I just had a Asus m970 chipset board, couldn't get past 4.1 without bsod's no matter what. Took it back and got a 99fx chipset board and can hit 4.6 with ease and probably 5.0 if I wanted to really tweak it. I'm just starting oc'ing and getting 1.1ghz more, but I needed a better board to do it.
