AFAIK, mobo has itz own mechanism to reset its own setting(if they r capable to) if u OVER-overclock.. ahhahaha. meaning, the mobo kenot tahan already.

xplanation using metaphor:
mum ask Johnny to wear the pink pants coz it looks nice. Johnny kenot tahan, once mum leave the room, he change into a Bermuda again. ahahahaha

datz wat i think personally. correct me if i'm wrong guys.. my AN8 only behaves dat way when it is overclocked. not in stock setting.

emilz, haf u tried checking the RAM timing? coz AFAIK, Abit mobos are able to reset the setting everytime an unsuccessful oc haf been done.. since uya proc aint clocked dat hi, mebbe bcoz of the ram.... juz check to make sure.. hope dat helps
