Having upgraded GPUs in a M4700 (Radeon 5100) and 7510 (GTX965M), no guarantee but TRY "DriverBooster" and if it finds a driver for the GPU. If so install directly via DriverBooster

Note: I don't like 3rd Party driver tools as you'll mess up your system over time (high latency due to non-OEM drivers means incremental micro-incompatabilities) but I have seen a few times that DriverBooster has an ability to recognise an otherwise unrecognised GPU and find a working driver when normal routes fail

Otherwise you might need to try driver-modding which is whole can of worms but might do the job e.g. I have successfully used (modified) Dell OEM Alienware drivers for the GTX965M with my Precision 7510

Chapeau! That's hardcore ... I had no idea the T1000 / T2000 were even made in an MXM-A form factor, I will keep my eye open

On loud fans, I have found Dell powerplans / power software and Intel Dynamic Platform and Thermal Framework (DTPF) drivers can affect this ... as my Dell 7510 with a GTX965M runs hot gaming (80-85C oveclocked)

The fan noise was reduced removing anything Dell-related and installing earlier Intel DTPF drivers, this without an impact on temperature. DTPF 8.1 driver for me runs the CPU noticeably (10C) cooler at load and far less "peaky" than anything 8.2/8.3+ that I have found

Powerplans - I use QuickCPU to take a copy of "Balanced" and tune it from there in QuickCPU

My old M4700 could sound like a vacuum cleaner when gaming - not sure if the above helps but worth trying

You can use an external monitor to view with the GPU or you will have to enable OPTIMUS in the bios, what I did, and I'm using Windows 10. If you enable optimus it will let you see your M4700 screen on your Integrated GPU and you can go into NVidia 3D settings and select which program, you want to use with the m2200 gpu, and it will work on your laptop screen just fine. This actually works out great because windows itself and other programs won't use your GPU and you will have all of the graphics memory available for the dedicated programs. It's 2023 and I have this setup and I can game on mine. Paid $150 for the laptop and $99 for the GPU. I'm currently playing Farcry6 on medium settings, so that's great. The battery won't last 10 minutes using the GPU, but you can run the M4700 as normal when not using the apps you select for the m2200. I did have to download some Nvidia drivers, the latest for the Dell m4700 should work. Version 516.25 is the one I'm using. Should work the same on the 4800.

I have a Dell M4700 and I installed a M2200 GPU in mine. I ran into the problem of the Nvidia drivers not working on it. I downloaded a different driver version, some of them will work. I'm using version 516.25. I turned a Dell M4700 into a decent gaming laptop for $250 bucks. I'm also using Windows 10. It was a headache, because I couldn't find any help doing this online, but figured it out. I wanted to share it with you all because it seems you are all having similar issues. 

As long as it's plugged in with an 180W charger it will work great, but the battery won't last 10 minutes using the GPU. If you are using Windows 7 or later you can enable optimus in the bios and use the integrated graphics for normal programs on battery power.

Enable OPTIMUS in the bios, download a driver that works with your laptop, then go into the GPU settings and select the game or program you  want to use for that GPU. I can do this on the Dell M4700, so it should work with the 4800.

Just added a Quadro M2200 to my Precision M4800. Other than the keyboard cable being a total mess afterwards, the mod was just a bunch of removing screws and ribbon cables. I used some good thermal paste and reused the AMD heat pipe that was on my prior card. I googled the nvidia version, and every one I found looked identical to the AMD one so I went with it. Everything seems to work fine albeit a bit hotter than I would like (it's a mobile workstation, so whatever).

@t4thfavor​ Hello, I have a Dell Precision M4800 Mobile W/S pretty well beefed up looking to install an Nvidia Quadro M2200 Graphics card in the M4800. I've already bought the card and for the life of me can't find any info about it until I came here. I was just wondering if you'd help and let me know what I have to do or any extra parts I need, (Like a new Screen) or different cables to get the M2200 into the M4800 MXM-A slot...?

Thanks in Advance...!  =)

I bought nothing extra. Just redid the heatsink paste and sent it. Seems to be fine after a year.
