    Hi !
    I'm currently playing with my antic GK106 i.e., GTX 765M.
    With a vbios mod, I can raise the voltage and the core, Memory is already at max clocks (5GHz w/ crappy 128bits).
    Anyway, I would like to know what are 'reasonable' voltage offsets, I don't expect precise, how much I need to put to get +x or +y, but how much voltage we can add for a kind of safe 24/7 use.
    I'm currently with +12.5 mV and + 150core :)
    Is 37.5 mV correct ?

    Don't go over 10% of your stock voltage for a 24/7 OC

    The card wont go pass the +12.5mV (+150 core)..
    Even with + 50mV it crashes with + 220 core.
    Seems like this GK doesnt like the OC.
    Have to stick with it until I get a GT72 (the only machine left with MXM slot).

    Take it slowly one step at a time. Needs more voltage if +50mV is not stable at +220MHz.

    GT72 is not the last MXM machine. It has soldered CPU and is overpriced af. The Clevo P77xZM/P75xZM and P17xSM-A/P15xSM-A are cheaper and much better options with both socketed CPU and MXM GPU.

    Tried +12.5 + 25 +37.5 + 50mV still crashes with + 200Core.. weird :(

    1. Did you use GPU-Z to verify that the additional voltage is actually being applied under load
    2. Try higher than +50mV

    just verified with GPU-Z it's applied
    But clocks work for 3 seconds during 3Dmark 11 1st test and bang driver crash.. will try 67.5
    edit : the GT72 970M is 1450euros, a clevo P177SM is 1650euros without SSD.. Europe is not meant for clevos :D

    whats your actual voltage?i got mine stable on 1.050mv and i dont consider raising it.I made a huge jump considering the stock was i think 0.850 or 0.862

    1,006V using GPU-Z (+12.5mV)..
