Yes, it's GA-MA785GM-US2H, AM2+DDR2 sorry the mistake, I based the config on the MA785GPM-UD2H over internet so it's a replace error. Similar motherboards also AM2+DDR2 are GA-MA785GPM-UD2H and GA-MA785-UD2H. Their PCB is the same. Seems difficult to get 3 values in BIOS, it stays almost all the time in the lowest value. Will try to physically measure the voltage, but can't promise.
