okay, so, i have this opteron 165, and an asus a8n e. I've had it overclocked to 3 ghz but i reinstalled windows and decided i would clock it down for the install just for stability sake. Now i try to overclock it, it will POST but then it gets stuck at the xp bootscreen. not frozen the progress bar just goes and goes and goes. I put the clocks to stock and goes in fine. then i got to thinking, what would cause that, i have no idea. can someone enlighten me?
