Vcore 1 5v safe? amd

No, DO NOT run it at 1.5v, anything over 1.43 is high, 1.45 is the absolute max it should be as specified by amd. I wouldn't go over 1.42v

I have the same cpu and its running happily at 1.35 stock voltages, any lower and I get bsods.
 


Don't OC. Overclocking is dangerous and some devices simply can't be pushed any further. You get what you pay for and that's the marketed speed.
