    Any here can share which .inf and section they mod for 980M in M6800's?

    I'm "stuck" on older drivers that I got from Windows Update but noticed I get wierd stutter every 30-50sec or so while using Optimus and gaming on internal screen, when on external screen or Optimus disabled in bios, stutter is not there.

    When I modded some 44x.xx drivers last time, stutter was gone, but gpu wouldn't turn off while on battery, tray icon would stay green, no programs would be listed as using it and according to various battery info programs and hwinfo battery drain would be around 30-35ish W.

    I'd like to get rid of stutter and battery drain so plx plox help

    I never managed to get Optimus working on my 970M and M6700, it would keep it constantly on, that's why I disabled Optimus, I also gained a little bit of performance by doing so.
    It might work better if you modify the inf entry of an "Optimus working in the M6800" card for your 980M.
    But 30mW looks like Optimus is working, an idle cpu is probably draining about 1 or 2w, which is a lot more than 30mW of your card, when my 970M was working without Optimus it would draw around 3 to 5w at idle.
    If you think you are getting a battery drain it might be Optimus not working (and monitoring tool would be totally wrong) or it might be something else.

    @darkydark Did you mean to report 30-35 W instead of mW? (Big difference there.)

    Yes i did, edited.

    But i want Optimus, its a neat feature on the go and extends battery life quite a bit

    I did try several cards, but M6800 cards were capped architecture before 980M, will give few quadros a go on weekend and hope for the best.

    Was hoping that someone here knows hardware ID of a Clevo or MSI or whatever notebook that had Optimus, 4th gen and 980M so i can shorten my search.

    If you can follow the data in the INF around a little bit then you should be able to figure it out.
    Look in an INF for GeForce 980M.

    > NVIDIA_DEV.13F8.06DA.1028 = "NVIDIA Quadro M5000M"

    Follow the hardware ID string up to the part of the INF which assigns it to a section.

    > %NVIDIA_DEV.13F8.06DA.1028% = Section047, PCI\VEN_10DE&DEV_13F8&SUBSYS_153F1028

    Go look up that section (search for it enclosed in brackets like "[Section047]").
    Right there are a list of configuration options.
    If you see NvSupportMSHybrid = 1 in the list, then you have found the ID of a card that supports Optimus.


    (You can't just add this line to any section and have it start working properly with Optimus. There are other options that matter and I don't know what they all are. But you should be able to change the corresponding device ID in the file to match yours and then have it work.)

    Hi there.The Tesla M6 is still working strong on my M6800.
    As Aaron stated ,no external video is possible,but for me was a great solution to expand the life of my machine.
    Remember that you have to leave Optimus enabled on the Bios beforehand.

    If you forget,best solution is to disconnect the little battery that feeds the system for a few seconds and the Bios will reset to default settings.

    All this info is only valid for Win 8.1 x64 which is my main OS.I did not test any other settings,so I can not elaborate any further with other OS.

    Keep in mind that for that to work you will need to mod the inf file on your Nvidia drivers.The drivers are a bit tricky to make them work.There is plenty of info on how to do it here on the forums.

    That is all.If you need any further info please let me know.I will be more than happy to help.

    Cheers.
