I've had an AMD Phenom II 955 Black Edition CPU for just over a month or two, I got it late august/early september. I also have an asus motherboard, meaning I've got a core unlocker, it's told me that all 4 cores have been activated up until today, and today it said 3 cores were unlocked. Does this mean that the 4th core died already? I'm going to check in my BIOS as this thread starts so I'll be right back.
