    So I have a clevo P771DM-G
    With 980M nvidia 8 GB, Gysnc card

    BIOS SAYS
    GPU GM204-B
    Rev A1
    Bios version: 84.04.67.00.0E
    Samsung memory
    8 GB
    Device ID 10DE - 1617 1558 7703
    Schenker 1558

    Tried to to find some bioses these are the ones I found but not sure if these help me in any way.

    So I try to undervolt but there are no options in MSI after burner for me at all :( everything locked.
    I use nvidia inspector and put max underclocks -135 mhz gpu and memory.
    My default clocks are: 1037 mhz gpu and 2506 mhz memory.
    So after putting the max underclocks of -135 mhz gpu and -905 mhz memory. I get
    987 mhz and 1598 mhz memory
    But for my calculations it should be 902 gpu and 1601 memory.
    So I don't know why it differs and I get higher GPU mostly..

    I used GPU-Z to extract my bios and open with maxwell tweaker. I see like extremely alot values. but I do see the voltages. But it is not one voltage setting. and I wouldn't know what to safely edit.. It may end up not booting at al.. So I don't think im suppose to edit it like this.

    It would be safer to edit via windows.

    Can you decrease the power limit? Decreasing the power limit and raising the clock speed would be a way to undervolt.

    In Nvidia inspector I see power and temperature target? if that is what you mean? 0 to 100%. But it is greyed out.
    I don't know where the 'power limit" option would be. At any rate if it is in the Clevo bios. Then I don't have it since my bios has almost 0 options about anything...

    Why are you undervolting and underclocking in the first place? What's the problem?

    Have you tried GPU tweak II? It works for me.

    Thank you for taking the time to reply. I don't want to derail my topic by talking about that. Just know I need to underclock and undervolt. Do you have anything that might help me on that?

    Do you have a maxwell mobile GPU? I just tried GPU TWEAK II.
    I noticed a few things.
    It doesn't allow me to declock my gpu at all :(
    And for underclocking it allow allows me to underclock -38mv.. I tried to apply that, and it simply resets to default. Somehow I can't apply it?

    Sounds like it may be a bios issue possibly. Next to doing something with coding, or using a lower wattage power supply, I am not sure.
