Hello (This is my friends account because a confirmation email wasn't sent),
I've previously overclocked my CPU to 4.2 GHZ and at this speed it ran with stability. But I was told that I could easily achieve higher speeds as the temperatures when ran with prime95 were quite low. So I attempted to overclock it to 4.6, but received multiple overclocking failures. I tried lowering the speed until it worked and that was apparently at 4.3, which wasn't much difference really. But when I run prime95 now at 4.3, I receive either fatal errors or illegal sumout errors on always 2 cores (Random cores, just always 2 fail). Why am I recieving these messages. Also, in the BIOS I set my voltage to auto if that's any consolation.
