Its still a bit of an unknown what vcore will seriously damage these cpu's. My temps are great so that is one worry out of the way. I ran 1.65v through my Opty 170 for a year without problems when the big 'don't go over 1.55v and deffo not 1.6v' was being bandied about. I wouldn't risk it if I couldn't afford to replace it. I don't want to push it too far though, I don't have the balls to go past 1.65...need phase for that imo.
I used 1.85v on mine
