Not sure if its the Vdroop or just a dud chip but it takes a good amount of voltage to get my E6750 to 3.64ghz stable. As of now I have it at 1.58V in bios (1.56 in windows). My temps are still good with my thermalright Ultra 120 extreme... high 30s at idle and low low 60s under load. Ive always read to keep it below 1.55V. Am I safe at this voltage? Its totally stable in orthos for up to an hour and then I stopped it.
