    +25mV Overvolt worth the risk? (980M)

    When I play battlefront my GPU cant hold its standard boostclock of 1126MHZ (no OC) cause of power limit, (temp only 78C...)
    In nv.inspector I can apply +25mV. But is it worth it? I never done that. Will that guarantee stable 1126MHz and better fps (+ OC?) when I dont have any temp problems?

    Adding voltage will only reduce the clocks as the card will use even more power. If you're hitting the power limit you do not want to overvolt at all.

    ah k, so would UNDERvolting help? If I had a modified vBios for example?

    If you do overvolt, you will need to overclock too.

    Usually these cards can handle 50-100mhz without overvolting so you should be able to undervolt and save some power to get you up to the top boost clock. The best you can do is just experiment. I personally dont like messing around with the modded bioses after my machine fried. I was pushing mine further than i had for about 20 mins which made me think i went too far.

    But yeah no real risk from trying an undervolt other than having the game crash if you go too far. Could save power and help you get up to the top boost. Also a slight overclock up 50mhz should be very safe. Many people go up 100 or more and are stable.

    till You will not reach more than 85 celcius it should be ok, but I don't know if that high temps will have impact for degradation gpu, 85-90 is really the limit and most for the benchs only, with 24/7 I guess is not so good

    Just click my sig. and grab the Clevo 980M MXM mod if you have an 8GB model.
    (Hardware is identical to your MSI card as long as vRAM capacity matches)
