Just curious guys, but does everyone run their oc systems 24/7???
'Cause it makes sense to oc your system for gaming or encoding, but when your P2P client is running overnight, all that extra power is overkill, no good for your HW, your wallet or the planet.
I use the profiles in the bios to load default recovery settings with speed stepping enabled. 1.1v on bios instead of 1.55v lets me sleep with a clearer conscious at night.
Then, when it's time to play, a simple reboot, F12 to load the oc profile, F10 to save settings and reboot into windows, load COD4, Crysis, Witcher whatever!

Just thought I'd throw that out there.
I'm not exactly that green but a decent 24/7 oc of 8x400 was rock steady @2.66 is fine & easily achieved.
