on my 1.33 Axia is it necessary to change the default voltages if my system posts where the bios voltages take over. from what i understand during initial boots your default voltages take you up until the bios voltages take over. so if my system is default set to 1.7 volts and my bios is set to 1.8 would it be necessary to increase the default voltage. currently @ 1.507 thanks....
