Hey guys need some help! I'm trying to get a 550 unlocked and stable but having issues with a core. First the CPU unlocks to a quad and boots, no freezing or crashes. However, almost every program crashes to the desktop. I ran Prime95 and core 2 fails immediately. So, I'm trying to figure out how do disable that core but i'm not given that option in the bios. Only option is core 2 and 3, which I've disabled both with no luck.
