Not crapping this thread but AMD specifically told me running over 1.5V on the Nb will kill it in a matter of days thru electron migration.

I advise 1.5V max as does DFI on their forum, with jumps to 1.7 or so for benching but NOT 24/7.

I revised my OC guide on this advise and would advise caution running the NB voltages shown here.
