    I am now using a GTS 160M and the TDP is only 35W
    3D gaming mode ,volt is 1.09v
    normal mode is 0.9v

    GPU core temp is Max to 73-75C while running furmark 1.82

    I tried to get a higher clocks (like 700/1000 to 735/1080)

    I found the volt in the BIOS file can't be modified by Nibitor

    Is it possible to modify videocard volt by software ?

    eg. 1.09v to 1.15v

    the heat-dealing and power suply is without any problems

    Is it because nibitor doesn't support your card?

    Or is it just that 1.09v is the max?

    BTW I have never seen software that could change the voltage for mobile cards in windows.

    how about using WinHex to modify the volt in the video BIOS ?

    hardware mod seems dangerous

    Could work, depending on what the voltage regulator supports.

    If you do a hardmod, please post details, I might try one with my 3700m.
