For x2 owners 1.45v seems to be about max 24/7 for a QUIET setup. My PC is virtually silent. Thats with modded sinks and letting faneq do its thing mind you. YMMV

Current settings 3.22 @ 1.4v (might go lower v yet) Ram = 1076 cas 4 2.2v!! This board pushes ramz REALLY nicely. Back running beta bios, AOD didnt work with official bios 12 for me??. Have extra chip on hand, had to hot flash once already. Extra chip cost $13.80 after shipping US monies.

I was a little disappointed with the board pwm wise but in reality she is a stellar board overall if you can live with lower volts to your cpu. In a day and age of trying to live greener it is probably for the best.
