So I just changed the core ratio to 4.2 and 1.20v for the Cpu voltage. And then i stared stress testing it using prime 95 and used real temps to see the temperatures. I get 48-51 C for all four cores but after about 8 seconds my whole system freezes. Can anyone help me overclock successfully? Im trying to free my CPU from a bottle neck in a game.
