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.

I am still wondering if I even should attempt flashing the bios. I mean back on my M6600 I tried to flash the GPU for a bit of overclock, the Firepro M6100, but it never worked and I had to take the machine apart, flash the BIOS chip on the board and put it back together to get it working again.
By what I have tried to find about this particular GPU it seems like its bios is actually stored on the laptop motherboard? I have no clue. Mostly just dont want to make a brick out of the thing. Or to take the laptop apart.
Mostly I just would like to get the power limit off to the 110W that the laptop should be capable of. Becouse right now it is power limited.
Burned my self so many times and revived so many devices from a brick I cant even count but its just so time consuming.
Some BIOS files I found on TechPowerUp could potentionaly work but I am not much sure about the Dell ones as they might be ment for that new type of boards and I have no clue what can happen.
Over still I feel like I will cave in and do it... If I find a BIOS that I will feel confident flashing that is. Probably.
