How did you overclock at all? Tell me what all you disabled, like C1E, EIST, HPET, etc. I raised vCore and vDDR, as well as vMCH. I don't know what the deal is. Maybe it doesn't like my RAM? The board still has some RAM incompatibilities. Maybe that's the problem? It won't boot it over DDR2-800 for some reason, when the default SPD profile is DDR2-1000, 5-5-5-15, 2.1v.
