    The cable is not compatible with the M6800.Could you just get the lcd panel off the bezel and install it over the broken one?
    To get the LCD panel alone should not be very complicated.I think it is your only option....that or returning the panel.

    I tried that but the actual cable inside the casing to the panel is different.....

    Then clearly the panel is not the right one.
    You could try to buy the LVDS cable for the M6800 and try it.
    Did you consider that?
    The cable is like this one.[​IMG]

    It's sad since these machines are getting old. I wanted to replace the 1080p LVDS panel in my M6700 just a few months ago because my LG panel got some dust or something stuck behind the front layer. The only panel that I could find was a AUO B173HW02 (it looks like this is the only 17.3" 1080p LVDS panel that is still being manufactured). This one, it looks like it is still for sale.

    I did not have a problem installing it but I did not like it, it was much lower quality than the LG that I was replacing... Worse viewing angle, "gridlines" visible, and terrible blacks especially near the top of the panel. I was looking again at eBay just now and there are basically no options. I guess someone could purchase a whole system used just to take the panel out...

    Anyway, I gave the LG panel a series of good thwacks and got the dust to move out of the visible area so I am still happily using it. Need to get another 2 years or so out of it before I'm upgrading laptops...

    I'm sure I'll try again once I get over my rage....this thing has a perfectly working p5000 in it (I tested the repair on an external screen)......... just right now I'm incredibly angry at sellers who have no idea what they are actually selling......

    i put a p3000 in mine along with a half decent chimei panel in and im only in it for around 500. way less than a newer system, and i got to tinker with it. even has 32gb of ram. and an i7. all in all a decent gaming laptop. although i do have the older lvds display and because of that i have to use optimus for graphics but with overclocked intel graphics it seems to work just fine.

    i am planning on putting a rx 480 mobile in my m6800. i have the card, just waiting on an x-bracket from china. my friend who also owns a m6800 told me it will work (apparently it just doesnt have working fan control so you have to use some other program to control the fans) so fingers crossed i guess.

    Hi, does someone here got an GTX 1070 mxm laying around ?
    I would like to try if a slightly modified P5000 vbios would work with the 1070 in the M6700 or M6800 :)

    Hello,

    Hopefully this us the correct place to ask, and maybe a few of the more knowledgeable members here can provide input on this question that I have.

    So I own a Dell Precision M6800, currently equipped with a Nvidia Quadro K5100M 8GB (GDDR5) GPU.

    What I wanted to know is, what is the BEST GPU that this laptop can support?


    I have recently been doing research into the various newer MXM-based GPU options and have discovered that PNY are releasing a Nvidia Quadro RTX 5000 16GB (GDDR6) GPU that is a MXM 3.0 Type-B module, so hardware wise should be compatible with the M6800.


    Does anyone know if it would be compatible or not?

    Where can I look to find more information on compatibility of Nvidia Turing GPUs with the M6800?


    Many thanks to anyone that can offer input :)

    Please review the M6800 GPU upgrade thread.
    http://forum.notebookreview.com/threads/graphics-card-upgrade-for-m6800.806352/

    Bottom line — Maxwell yes, Pascal maybe, Turing probably not
    (Note that an INF modification will be required to get NVIDIA drivers to load no matter which card you pick.)

    Maxwell GPUs work fine. You can install a Quadro M5000M or a GeForce 980M.

    Pascal GPUs have a vBIOS conflict. They work under Linux, but under Windows you will always get a BSOD at boot (even if trying to boot Windows PE or the Windows install media).
    This can be worked around using early "engineering sample" vBIOS images that have been found. You can boot into Linux to flash the vBIOS onto the card, and then boot Windows normally. There are working vBIOS images for the Quadro P3000 and P5000. There is one that works for the P4000 but it prevents turbo boost, so performance is lowered. No working vBIOS images have been found for Pascal GeForce cards.
    @DynamiteZerg has a working M6800+P5000 configuration. @JEAMN tried the GeForce 1070 and sort of got it working (taking more deep/technical measures to get around the vBIOS/BSOD issue, which you can read about here), but abandoned the project because of stability issues. I tried running the P5000 in my M6700 and did get it to work in Windows after a vBIOS flash, but I also had to abandon it because of stability issues. (Random BSOD every few days.) @bobmook had a P5000 in the M6800 as well, it worked for a while and then needed to be repaired, I'm not sure what the current status is. All around it seems like a risky proposition, considering the cost of these cards.

    Turing GPUs have not been tried but it is very much suspected that they will have the same vBIOS conflict as Pascal cards, causing Windows to BSOD at boot, and that there will not be any vBIOS images available to get around it.


    Also note that there are two versions of the NVIDIA GPU heatsink in this system. One of them has a protrusion that prevents Maxwell and newer cards from being installed because of the different VRM placement. You will have to dremel that part off or locate the more rare "flat" NVIDIA GPU heatsink. This is also discussed in the GPU upgrade thread.
