turn off all amd features in the bios. then you should be able to modify your voltages.

I am in the exact same boat, similar board same chip. If I set everything to auto (including voltage) and up the multiplier it raises my voltage to dangerous levels. But I can't do it manually because it fails overclock.

Go back into bios and manually set ur ram timmings and set ur ram voltages to what it says on the sticker on the ram itself. U have to take cpu voltage off auto and set to the lowest setting u have or voltage will climb with overclock.

I think that i have resolve default voltage with update of bios,so i have 1.290V at 2.8ghz that i have set at 3.2ghz
__________________ but from bios i have max voltage at 1.440V so i have test,with orthos for one and half hour at 3.5ghz stable!! So if i would like set up more CPU i must use AMD Overdrive.....P.s. I have resolve the default voltage but i have still problem of instability of voltage!!
