Well this chip has been running well over 1.65vcore for a couple weeks now every night for a few hours benching/playing, up to 1.32vtt, and up to 1.80vdimm. Im waiting for it to die but it just keeps going. I got these 2500k's to play with, not to worried about the longevity. It has been fun to just say F-it, give it some juice and have a blast. Im sure it will come to an abrupt end one night benching but for now Ill keep having fun.
