    Hi, is it possible to upgrade a P771DM-G Clevo with a P775DM2-G Mainboard or a similar to get the newer Clevo GTX 1080 or RTX Cards working? Or anyone who had tried this before?

    Certainly with the p870 series such an upgrade had various factors hurting this. Partly the shape of the GPU is different so the chassis is a bit different iirc on this model.

    This is not possible.
    First you need 775DM3 MB, which have a different layout from P750/770DM MB, esecially in MXM connector placement, ports placement and CPU heatsink screws placing.
    You will need a P775DM3 case, P775DM3 palmrest, P775DM3 bottom covers, P775DM3 12V Fans (Cause in P770DM fans are 5V, and in P775DM3 = 12V), P775DM3 heatsink for CPU And GPU. You just need all parts from P775DM3, so it's better to buy P775DM3 instead of build P775DM3

    You'll be better off using the mod to get a higher gen CPU and using a standard MXM card.

    An I9-9900T ES is already installed. I‘m thinking of buying maybe a P4200.

    It could be that it’s unlocked. Didn’t test it yet. Basic frequency is 1,7Ghz

    Yeah they are the low wattage version so that's pretty normal for the wattage.

    @Meaker maybe you can help me. Now I have a black screen on my P771DM-G. There is a Dsanke Mod bios inside. I tried several 980m in my device. After that the black screen comes on. After many times of power drain I now get a picture via HDMI. I checked the screen in a GT72. It’s working fine there. Could that be that the Dsanke Bios got faulty? Also when I saved and exit the BIOS before the black screen comes on it takes 10-15 seconds until it restarts.
    Maybe I have to flash the Bios again directly on the Chip with my programmer?

    Update: so now I got a pic via HDMI back.
