    GT240M - can't undervolt

    Hello,

    Here is a BIOS rom* of a GT240M MXM card that I can't undervolt. I would like it to run at 0.85V (second VID) in 3D, or at least try it, but NiBiToR 6.06 can't modify voltages on this rom and Nvidia system tools don't allow to adjust it.

    So I ask for help and advice here.

    Yours sincerely

    * - just remove .txt from file's name in order to view rom.

    I have the desktop version of that chip, for me it only had 3 voltage steps (Idle, Load and Throttle), something to do with the limited VRM implementation. I only managed to remove the throttle voltage and replace it with the load voltage but to undervolt, you can only really force the Idle voltage on the Load and throttle profiles.

    I would prefer to force thorttle voltage (0.85V, i assume) to load voltage, but I can't modify it with NiBiTor, maybe someone can help?

    Nevernind, since temps are OK, I'll overclock it instead.
