Now it got verrry interesting!! I used the AMD OverDrive Utility to boost the CPU cores 50% (Novice mode). The machine became unstable (BSOD). I tried to decrease the boost, but now I'm back to where I started:
I'm not into gaming, the most compute intensive thing I might do is DVDFlick, so i'm really not impacted. But I'm very curious whether BIOS detected one, or both, cores were bad and disabled them? Can one of the cores still be good enough to use? Does Dual-core Phenom vs Quad-core Opteron make any difference? Thanks for any reply.
