Does that mean that my fourth core is bad? How can it be unstable when I ran prime95 with no problems?
not sure why this is happening, sounds more like the core is throteling down or something like that, what temperatures do you have without the 4th core?
have you tried different bios versions? maybe the version youre using locks the other 3 cores for some reason? o_O
when you run prime95 with the 4th core, do all the cores have 100% load?
