    Hey all just wanted to let everyone know despite what i see people being told the 980m 8gb Gsync version DOES work inside of the m15x. The only thing I did was change the active lfp setting in the bios to edp and it worked plug and play. I did have to modify the inf file but that was not too hard.

    https://www.3dmark.com/3dm/28345363? Firestrike score. Even though my Cpu was clocked at 28x28x28x27 stable at a low tdp and tdc I needed to increase it for the clocks to hold across all 4 cores. The max I've been able to get the gpu temp is 81 with firestrike looping for 15 minutes.

    I dont have any games to test properly atm, just showing more that it will definitely work. In the process of modding vbios to keep this thing cool

    Firestrike is a reasonable benchmark, though there are plenty of others. It is nice to see another example of 980m running in this machine. However, as others have noted, heat and power are the principal issues for the 980m with 920/940 processors near the limit. We all wish you well - perhaps you will find a solution that has been missed.
    Keep us informed.

    Max gpu temp was 65 degrees with the laptop resting on a textbook. I removed the pin on the adapter and it doubled my score so it is definitely needed. I don't have the double adapter but according to hwinfo the card never drew more than 87 watts

    If I overclock my memory I can get it to 3000 so far and my graphics score goes to 9k. My core clock seems stuck around 949 though boosting to 1040 ish sometimes.

    Playing arma 3 Gpu sits at 1231 core and 3060 mem @ 53 degrees


    EDIT
    Cranked up the settings to all maxed with 2xaa no vsync and the temps got up to 71-72 but thats not very bad. Frames were in the 40s

    One thing I noticed when installing the card was that with the stock screw the heatsink would not make proper contact with the card. I removed the front two screws and replaced them with ones that allowed the heatsink to make contact. Next I tucked a thermal pad underneath the metal bracket that goes over the heatsink where the fan screws in. This makes the back of the heatsink make contact with the rest of the gpu better.

    https://www.3dmark.com/3dm/28341880? The highest score I was able to get today. This was +79 on the core and +456 on the mem. The cpu was clocked at 28x28x28x27 60tdp 62 tdc. Increasing the tdc/tdp values past that didn't allow me to clock higher it just made my temps sky rocket. The gpu never went over 66 degrees according to hwinfo during all the tests (I ran about 12) so temps are not a problem.
