    I had to flash the EDID to get 85hz working. Intel Optimus doesn’t work with display overclocking.

    I have sold the 1060 so the 3920xm will stay with my 680m sli. :D

    How did you flash the EDID and what refresh rate were you limited to before doing so? My display is only capable of around 70 Hz, will flashing the EDID resolve this? Thanks.

    I used Linux...my friend actually helped me.

    Flashing EDID won't help with anything you can't already achieve.

    Only reason I flashed it was because with nVidia Optimus (1060 in SG mode) you are limited to the Intel Control Panel. nVidia Control Panel has almost no options for anything, so iGPU controls everything. Therefore no display overclocking. My EDID flashing it thinks its the native resolution.

    Both of my M18x can do 80Hz. You should be able to do 75Hz at least. Try running the computer for 30 minutes to let the display warm up, then try 75hz in the nVidia control panel.

    Actually I overclocked my display with Nvidia Control Panel under custom resolution:



    Are you saying that because you were running 1060 in SG mode (what is SG mode anyway?) that you lost this ability?

    SG mode = Optimus

    All 10 series+ requires SG mode which is Optimus.

    Optimus means BOTH iGPU & dGPU are active and the signal goes through the iGPU. This means iGPU control panel controls basically everything.

    Also means mDP is limited to 1.1 mode since 1.2 only works with nVidia in PEG mode.

    PEG is not supported after 980M series cards. PEG is dGPU mode only

    Yes, much safer than what I did.

    It's the proper way to do it. Just click test and wait 15 seconds if it doesn't work.

    Hi everyone,

    So I have now upgraded to the 3940xm CPU which is SO much better than the 3630qm I had.

    I also have a single GTX980m on the way to replace my GTX675m.

    My question is, am I able to just put the 980m in and it works out the box or do I need to modify any drivers or anything.

    I also have a GPU right side heatsink coming, I have attached a picture of two I found, are these the same or different? If so which one would fit my computer?

    Many Thanks
