    Yo everyone. I recently popped a 980M in my M15x.
    Is this firestrike score about right for 980M at stock with 920xm?
    980M at 1206mhz/1250mhz svl7 vbios,
    920xm at 3.5ghz (underclocked for now)

    The 980M is one hot card! FAR hotter than the 680M that preceded it! Even with liquid ultra on it the temps are barely under control in this old laptop with only 2 heatpipes!

    What are safe max temps for this card? 85C is ok for gaming?

    mid 70s is better.

    I undervolt my GPUs (and CPUs) so I don't like seeing anything over 70c, all of my GPUs (and CPUs) are generally under 60c when gaming. Generally, you want to stay under 80c, preferably under 70c.

    The 980M should be a cooler card than a 680M as far as I know. Maybe your heatsink just isn't too amazing with it? I don't know.

    I have similar results with stock 980M paired with stock i7-3740QM, so I guess it's all good.

    Isn't 980M a 125W card, compared to 680M 100W?

    Don´t know about the CPU but the Graphics score is good. I get everything between 9500-10100 depending on drivers stock.

    But as the others said something´s off with the temps, 980M is a cool card. I don´t pass 80C and am mostly sub 70C (stock speed and voltage, just repaste). Presuming a proper pastejob I´m with D2, sounds like a heatsink issue in some way. Is it the same you had before so you know it´s not warped or faulty in any way, or is it a new one that came with the card?

    I´m gonna stick out my neck and say 85C is "OK" for gaming. It might degrade a little faster but I wouldn´t worry unless it was at 90C+ for longer periods.
    That said 980M is capable of lower temps and sub 80C is preferable.

    The heatsink is fine. The problem is that it was originally designed for 75W cards aka 5850M and 260M (yes it is that ancient) the twin heatpipes lead to a fairly small radiator.

    Modern laptops almost always have minimum 3 heatpipes and a larger radiator.

    The cooling was able to handle the 680M albeit with load temps in the mind 80sC with an OC.

    The 980M is MUCH hotter as the card hit 75C before I even got in the game and then within 2 minutes shot up to nearly 90C under normal paste! If you compare the two cards the core on the 980M is quite a lot larger.

    I now have it under Coolaboratory liquid ultra and the temps took about 15 minutes to reach 85C and more or less stabilised at that temp. Might eventually hit 90C I guess during prolonged gaming.

    The 980M is running at 1V 1206/1250mhz with nearly 80% asic value. Really hot. Unfortunately I can't see a way to undervolt Maxwell myself!

    What I might do is lock it to the secondary 3D clock value if possible which runs at a lower voltage? Why can't I lower the voltage?

    You need a modded vbios to undervolt usually.

    I guess with maxwell there's no undervolting possible with user, the vBIOS should be coded like that and flashed.

    i overvolt and overclock and most games don't go into the 80s. has to be a cooling issue.
