    Is it possible to undervolt a GTX 780M while modestly overclocked? I want to undervolt to reduce temperatures as the GPU goes over 90C in my testing - not good! (already repasted, many times)

    How would I go about undervolting safely without damaging the card? I have modified VBIOS already installed. What are the undervolt limits that are safe to perform?

    Cheers!

    With an unlocked Vbios, you should be able to under-volt via Nvidia Inspector or similar program. For over-volting you should only change voltages by .01 at a time max... but for under-volting it shouldn't matter I would think. There won't be a chance of burning it out, just it won't get enough power to operate at full clocks if you do too much.

    Yup, what he said. SVL from Techinferno have made a vbios that unlocks the possibility to play with voltage. I was gonna do the same with my GTX 680M but I never got the time to do it. A shame really because its interesting, but be very careful doing it because you can screw up your GPU.

    Let us know if you are succesfull and if it worked out for you
