Great results A-Grey! I'm sure you're very happy with your OC.

BTW I found the thread about high voltages: http://www.xtremesystems.org/forums/...d.php?t=198614

I tried Ai Clock Twister Lighter, delaying the CPU uptp 400ps & NB 300ps, I even uped all the voltages by 2 steps with the result that IBT is sometimes stable & sometimes its not. That makes it even more complicated.

I would like to know if greg.m is using 1.77v on the NB 24/7.

I am also getting the feeling that Win7 x64 requires higher voltages. On top of that I have APIC + ACPI 2.0 enabled. A-Grey have you got those enabled aswell?
