    Strange.

    Taking the P3200 first as it makes more sense.
    VEN_10DE&DEV_1BA1&SUBSYS_08311028
    10DE = NVIDIA
    1BA1 = GeForce 1070 mobile
    0831 = Precision 7530
    1028 = Dell

    The identifier for the Quadro P3200 is 1BBB. I have no idea why it is showing incorrectly as a GeForce 1070. If you do this find-and-replace in the INF file, maybe it will work.
    VEN_10DE&DEV_1BBB&SUBSYS_08311028 => VEN_10DE&DEV_1BA1&SUBSYS_08311028

    Next, the Quadro P4200. This one is totally whacked...
    VEN_10DE&DEV_1BA1&SUBSYS_95E11558
    10DE = NVIDIA
    1BA1 = GeForce 1070 mobile
    95E1 = ?? (Some Clevo mobile workstation)
    1558 = Clevo

    95E1 and 1558 show up only in nvcvwi.inf, which is the Clevo stuff. All of the Dell stuff is in nvdmwi.inf. The closest match that I see is PCI\VEN_10DE&DEV_1BB9&SUBSYS_95E11558, which shows as Quadro P4200 with Max-Q.
    Anyway, if you do this then maybe it will work.
    VEN_10DE&DEV_1BB9&SUBSYS_08321028 => VEN_10DE&DEV_1BA1&SUBSYS_95E11558


    Rather confused why they showed up this way. I've never heard of the hardware ID values being picked up incorrectly. Maybe these cards were flashed with a GeForce 1070 vBIOS? Can you get the vBIOS version from GPU-Z?

    If @jpnankervis purchased his DGFFs not from Dell, this might very well have been the case, and these shadier places might even have recommended that the user install an appropriately modified driver, as you suggested.

    The thing I'm curious about is how the cards would perform with the GeForce GTX 1070 vBIOSes (if the driver mod is successful), and how the vBIOSes were loaded into the cards in the first place, without bricking said cards.

    Hello,

    Are any of these still available or they are all sold?

    Thanks!

    Hello,

    I wounder what is the status of this tread? are the cards sold already or still available. I got 7530 as replacement to 7510 because Dell could fix it. I got best cpu but only T1000 GPU. I am investigating possibilities if I could somehow upgrade it. Thank you in advance!

    The form from a few messages before is still up; you can continue to fill it in if you want to.

    I received a rather pleasant surprise today: my Quadro RTX 5000 DGFF2 had arrived, and I have installed it.

    Before I dive in, let me start with a picture, comparing all three GPUs I've used so far. From left to right:
    • Quadro P3200 DGFF2 (Dell P/N XDVC6)
    • Quadro RTX 3000 DGFF2 (Dell P/N MWDWM)
    • Quadro RTX 5000 DGFF2 (Dell P/N 8CMTP).
    [​IMG]
    This is intended to be a comparison primarily of the overall board layout, the GPU die size and port positioning. The P3200 and the RTX 3000 boards have a lot in common; nearly everything is in almost exactly the same position. VRAM count is the same, at 6 GB.

    Some other notes:
    1. I had to swap out the heatsink—details mentioned here in the last spoiler.
    2. The existing DGFF power cable was almost too short to fit into the RTX 5000's port, which has moved, as one can see in the photos. I just managed to plug it in, but it requires some finger gymnastics.
    3. The VRM set-up has increased for the RTX 5000. This makes it likely that it can support more power in, as it is currently set at 80 W.
    4. All three boards come with an aluminium EM shield (the latter two on both sides) to reduce anti-static discharge. This was removed to photograph the complete PCB configuration.
    The RTX 5000 board is testament to the fact that a powerful GPU, and 16 GB of fast GDDR6 VRAM can be fit onto a board roughly equal to the area of MXM-A. Whether or not it actually happens is merely down to manufacturer willingness to do it. Dell did, and I have now upgraded the GPU in my notebook, twice.

    This time, I actually performed some benchmarks to compare between the RTX 3000 and RTX 5000. Results are below.

    TL;DR: the 80 W power limit completely neuters the potential performance of the RTX 5000. I tried flashing the 110W vBIOS posted by @myshko here, but I was greeted with a black screen on boot-up. Flipping the Switchable Graphics option in the BIOS made no difference.

    All in all, an easy upgrade, but not particularly worth it.

    For science!
    No really, glad to hear that it works. Too bad the vBIOS swap doesn't work. (Wonder why that is.) Hope that Dell continues to keep the parts consistent so this type of cross-generation upgrade can be done. (Not really counting on it though.)
