For some reason it's hard to find that info on 65nm AMDs. Or at least the Phenom II 940. Recently talked to someone here
, info might be useful. Guy was OCing a Phenom II 940:
Well 1.325 is the area where AOD starts to turn red. As far as experimentation. I have change bios settings honestly about 115 times. lol. Its still running good. I was just looking for safe 24/7 final voltages.
