I remember i heard somewhere that MSI pro boards only let you raise the voltage .2 volts over default setting.... so if you want 1.85 you gotta connect the L7 bridges on the cpu... i made my duron 1.65 default from 1.5 default voltage... i'm guessing that since you can only get to 1.8 voltage that your default voltage is 1.6... if you do it this way, you can use the newer bios's ... just FYI
