Hello, I an having problems with my friends Gigabyte GA-M68M-S2P motherboard. I sold him my old phenom ii x2 555 which I unlocked to a quad core on 2 mobos, but on his only 3 of the cores work, but the forth core does work on his mobo only for 10 mins then freezes. Here's the wired part before he had a Athlon ii x3 the forth core doesn't work on his mobo, but on my mobo the forth core works. So I have no idea what's up.
