hello all guru!

i have a problem here. I just bought a gigabyte ma-57sli-ds4 mobo runs by athlon x26400 be with 4gig horsepower. Im still new at this OC thing but ive tried a few on my previous biostar and it works.

With this mobo, everytime i switch the hertz, volts a bit, its stop functioning until i restart several time. Gigabytes overcloaking software also didnt work well. i can only manage to increase 0.1-0.4hgz and the rest it jammed.

Any solution
