Hi there fellow overclockers seems I've run into a bit of trouble with my CPU, see a month back I decided to overclock my Phenom II X2 550 BE for all it was worth, got 3.92 GHz stable on prime and even stressed that out over a 48 Hour prime95 test that had no errors. Up until recently it was fine, then deciding to unlock it with my newly purchased ASUS M4A785-M and got me a newly acquired triple core BE processor....only 1 problem unless on auto and at the normal voltage setting I cant even get this thing to run stable at anything past 3.31 GHz. atm I have the third core disabled and now I cant get it back up to its former glory, so any suggestions for me?
