    When unlocking voltage control afterburner is showing 937mV as default voltage when it should be 1082mV. I tryed setting the voltage to 1.2mV in afterburner but my voltage did not change according to evga oc scanner which was still showing default of 1082mV.

    Due to error on MSI side beta 4 database unlocks extreme path of voltage control on 580 series via direct access to CHL VRM. This mode is intended for extreme overclockers only and it requires deep understanding of CHL VRM specifics from end user side to be used properly, so if you're not understanding CHL specifics - please avoid using it. In this mode you won't be able to see voltage changes in ANY tool reading voltages via NV driver because it works with VRM at low level, you will need to know you card default 3D voltage and set it manually, you will lose voltage switching related power management, and so on. So once again, avoid using extreme version if not a truely experienced overclocker and if you don't have understanding of CHL VRM functioning principles.

    I'd just unlock the bios and use beta 4,for up to 1.21v,all software volt settings i have tested accurate with ddm.
    This method does not mess up other p-states.

    so basically when I change it to 1.2mV its really being changed to 1.2mV I just cant see it in oc scanner or any other software that detects vddc. correct?

    yes.
    use dmm at first always,then you have referance point as to what software provides.

    Error in your understanding. Reread the previous post and avoid using it, if it doesn't tell you anything.

    My GTX480 works well with the MSI AfterBurner1.6.0beta 6 Extreme. I would like to test my GTX580 with MSI Afterburner Extreme.
    GTX480@1,302V
