I really must thank you guys. It was a project that took a little longer due to some unforeseen events, but in the end I was able to assemble my Dell M6800 station.
Initially the processor was going to be a 4980hq, but because the one I received didn't even work, I had to return it and decided to buy a 4930mx. The next thing I did was change the AMD graphics and build a Quadro P4000 that I managed to build by changing the bios to the ones posted here. And then I upgraded the ram from 16 GB to 32 GB, although this did not make it run at 1866 but at 1600, but I am happy. Then I changed the keyboard to a illuminated one and changed the DVD player for the DVD rewriter, which I also saw was a Hitachi brand, which is synonymous with quality. I put an Intel® Wi-Fi 6E AX210 card and a Sierra MC7455. In the end I managed to avoid the card problems by putting tape on the pins that a colleague explained to me and changing the firmware. When changing the firmware, I entered the console and changed the USBs and it no longer caused any problems. So I'm left with a pretty decent laptop, it doesn't really get too hot, at most the CPU and it hasn't gone 90 degrees at maximum effort. The Quadro p4000 simply hasn't gone over 67 degrees for me. Simply incredible card. I forgot to mention the panel on my laptop is EDP. The screen is magnificent. The only thing I couldn't get to work correctly was the fingerprint. I installed the latest firmware and the latest drivers and it still gives me a dirty error.
