Dell Precision 7710 Quadro RTX 4000 upgrade problems

[Intognito]

Some time back I was able to get my hands on an MXM Quadro RTX 4000 from a HP ZBOOK 17 G6 and decided that I will try to install it into my laptop. It required some modification to the MXM slot and heatsink as it would not fit and the card is not fixed by anything, no screws were used. But suprisingly the temps are not bad.
Most annoying anoying problem is the device id, which doesnt let me install drivers automaticaly and if a manual instalation is used games wont be able to turn on DLSS altrough RTX is still functional. If I install drivers with NVCleanstall and configure the device ID then everything works.
The main problem is that
1. the power limit is 90W
2. card BIOS is reported as Dell in windows, HP in linux and I dont know if or how to update it so the card runs as intended. (if even something like that exists)
I have to say that compared to my old experiments this one was mostly painless and performance is better than my old M5000M but if anyone would have anything to say I would be glad to hear it.

In a laptop, the GPU’s subsystem ID is derived from the laptop’s motherboard, not from the GPU card itself. That’s why it is reported as a Dell card in some tools, and that’s why you have to do some mucking to get the drivers to install. Nvcleanstall can “fix” this for you (as you have found), but you could also make some manual edits to the driver INF file to get it to install cleanly.

 

You can still flash a different vBIOS on it by passing a command flag to nvflash to ignore the difference in the subsystem ID.

 

There is no “working as intended” setup for this because this GPU+laptop combo was never “intended”. But if it works, it works, and I bet it is a step up in performance.
