    I purchased a Quadro P4200 to install in my Clevo P750DM-G. I believe it comes with the HP vBIOS. I do have a TL866II programmer and can program the vBIOS before installing it in the system if needed, but I'm curious if that will be necessary. I have done several mxm swaps and have no problem with it. The last one I did was a GTX1060 in this same machine.

    Advice on this will be appreciated.

    Thank you

    I ordered a chip from ebay that supposedly has the Clevo vBIOS for the Quadro p4200. I will post the results here once I get it all soldered up and installed.

    I soldered on the vBIOS chip and installed the P4200 into the P750DM, however, when I installed the driver, the screen went blank for 5-10 minutes before coming back on scrambled, but mostly black. I have done this twice now with the same result. If someone can help me acquire a Dell vBIOS or other vBIOS known to work with Clevo, it would be greatly appreciated.

    I'm not sure what to do next here to get this working, any help or advice will be greatly appreciated.

    This P4200 Dell vBIOS resolved the problem. Drivers are now installed and it's up and running benchmarks now that I will post in a new thread.

    I was looking forward to it also. They are up in another thread. Do you know if thermal throttling on the CPU can inhibit GPU scores in the benchmarks? If so, the numbers could go up once I get the shim on the cpu side.

    Here is the link to the other thread with benchmarks
