    Played around a little bit again, think I'm getting closer to the sweet spot, ran FS with -12,5 mV, C +155, Mem +360

    FS: 11736 points
    https://www.3dmark.com/3dm/38522286?

    If I go beyond that, FS "crashes" and Afterburner gives me 0 value on most of the readings, maybe that's the driver limiting or the MB design.
    (though the 780m is well balanced regarding stock Voltage).

    @ssj92 next time when you have some spare time, could you please run FS with -12,5 mV, C +160, Mem +365 / +370?

    What vBios are you using? Mine are on 80.04.92.00.02 which is what they shipped to me with but I'd like to experiment a little.

    Would you have a link to it by any chance?

    Awesome. Thanks!
    I'm at work anyway so I'll wait for confirmation and I'll do some research into how to flash since I've never done a vBIOS before.

    Not that hard, nvflash, command prompt and some specific commands or the real and oldschool USB Stick way. Note that there is a risk, like with any flash.

    Without risks are we really living?

    You have much better 780M than me. I can't even get +100/+200 stable at +12 voltage: But mine still score higher
