Maxwell GPUs don’t require any vBIOS work. Note that Tesla M6 doesn’t support direct display output and can only work through the Intel iGPU via Optimus. Also, you do have to do a little mod to the GPU heatsink to get these cards to fit.

If you can "make it fit" (and I would genuinely love to see that), then it will probably work. I have never heard of this being done, but... The physical interface is the same. I don't think there will be an issue with needing to modify the NVIDIA driver INF.

You can check pictures. It can't be done, it won't physically fit.

Use a tool like CPU-Z to check the RAM specs for the modules that you already have installed. In addition to the speed, you want to match on the CAS latency. But it should be fine to mix manufacturers.

I haven't actually used NVcleanstall myself, it wasn't around back when this was something that I was fighting with. I used a Quadro M5000M in the M6700 from probably 2017 through 2021. I can point to my notes about modifying the INF file by hand: https://www.nbrchive.net/forum.notebookreview.com/threads/precision-7530-precision-7730-owners-thread.820539/page-253.html#post-10937563

Basically mirroring @JadeRover. Unsupported GPUs will always show as "unknown" in BIOS. This is normal. You also need to do an INF mod to install the NVIDIA driver. This is also normal when you don't have a "supported" laptop model / GPU pairing (at least with NVIDIA). I used to do this by hand, but these days I believe that the tool "nvcleanstall" can do it for you.

You don't need drivers for a specific CPU. Dell doesn't offer any "CPU" drivers for the Precision M6800 (or any other system). The chipset drivers are there for other onboard components, not the CPU. Cache is managed by the CPU itself, not the OS/drivers. There's no issue running any "compatible" 4th-gen CPU in the M4800, other than the RAM slot limitation that has been mentioned recently.

OK, sorry about that, I do subscribe to The Verge so I didn't realize that they had a paywall on this article. Couple more. https://www.windowscentral.com/hardware/dell/dell-xps-returns-in-2026-after-rebrand-flop https://arstechnica.com/gadgets/2026/01/dells-xps-revival-is-a-welcome-reprieve-from-the-ai-pc-fad/ Dell is bringing the XPS name back (in addition to the Precision name, it seems). The Pro/Premium/Plus/Max names that they introduced last year is already being phased out... though not completely ("Precision" is now "Pro Precision").

"Broadest PC portfolio ever"? I already think part of their problem is that they already have too many models for each generation. How many 14" laptop models do you need to be offering at once, really? Slim down the product line, and use that leftover engineering effort to focus on polish and attention to detail. Add more spec options to each model if you think that people need options.

Nothing says that your superlative branding scheme was a mistake ... like rolling it back? https://www.theverge.com/news/851047/dell-xps-14-16-13-laptops-brand-return-ces-2026

I have personal experience with this same thing, with a Precision M4800 and ePort Plus dock. What I recall is that it is just pretty finicky about passing through a 60 Hz 4K signal. It is possible but it doesn't always work. I think that it is just because of the "wiring" not being high quality enough to make a signal with the bandwidth required stable. The dock doesn't support a specific version of DisplayPort, at least when it comes to its "electronics". That is determined by the system. (It may support a specific version of DisplayPort just in the sense of being "rated" to pass the signal through.) Unlike "modern" docks, an ePort dock is basically a glorified adapter + extension cord. It just passes through traces from specific pins on the dock port on the bottom of the laptop to the ports on the dock. It doesn't have much inside in the way of electronics / processing the signal. (It does have a DisplayPort→DVI adapter which is used for the DVI ports.)

There are different coolers for AMD and NVIDIA (Kepler) cards in this system. I think the main difference is accounting for the die height. It would be best to get an NVIDIA GPU heatsink. (Not sure about thermal pads, sorry.) You can use a PCIe (NVMe) SSD with an adapter, if you can get it to physically fit. The BIOS won’t be able to boot from it.

If it's happening even on a Bluetooth device that is connected, that's not an analog/grounding issue. The Bluetooth audio chain is all digital until it gets to your actual external speakers/headset, which wouldn't be physically connected to the laptop. I'm glad that they dumped Realtek as the sound chip manufacturer, I never liked them, but I don't know if Cirrus is any better. In any case, I agree that this buzzing is unacceptable. Again, if the buzzing is observed even over Bluetooth audio, that points more to a software / audio stack issue. The first thing that I would check is make my way to the "legacy" Sound control panel and disable "audio enhancements" for your sound output device. Dell has been known to include a stack of audio "enhancements" with the "Dell Optimizer" package which have also always been undesirable to me.

Here are references to Pro Precision 9. https://registry.dmtf.org/products/dell-pro-precision-9-t6-pw9t6260 https://registry.dmtf.org/products/dell-pro-precision-9-t4-pw9t4260 https://registry.dmtf.org/products/dell-pro-precision-9-t2-pw9t2260

I think that's on point and there's also this shift is also going on because ... Each major architectural advancement costs way more than they used to (in R&D, and also in just what it takes to get chips using the latest fab tech). Each major architectural advancement also brings less benefit than they used to. (Gone are the days when performance doubles every couple of years. Now we get maybe a 20-30% performance bump or something in the same timespan, at best.) You have NVIDIA claiming giant generation-over-generation gains, but that's not all from the architecture, it is also from increasing the power draw to their chips and "playing with the numbers" by rolling in new "things" like DLSS / AI frame generation which don't really make for an apples-to-apples comparison. With gains costing so much more, it makes sense that there would be more incentive to hang on to the "current" generation and extract as much profit from it as possible.
