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.

Ty all for info. I didnt know it. I must understand that the failure is a conflict with the USB 3.0 controller. But isn't there any firmware for Sierra that works to solve this problem? Edit: Do you think that a DW5821E with a mini pcie to m2 adapter would work without problems on the wwan port? Edit2: I found solution i think on Sierra. Last firmware i think you can change usb speed. at!usbspeed? SUPPORTED:Super-Speed CURRENT :High-Speed OK at!usbspeed=? !USBSPEED: <max_supported_speed> <max_supported_speed>: 0 - High Speed 1 - Super Speed OK

And which is the idea of covering the contacts indicated? I mean what is the benefit?

Taking advantage of everything, I have a question. Does anyone know if there is any option to install a Wwan card without the USB ports slowing down so much that they barely load anything? When installing a Sierra MC7455, the moment I put in a USB to install Windows it takes about 10 minutes to load and it is very slow. When you remove the card it takes about 10 seconds to read the USB. Edit: I found Wwan cards work with ubs line so, if i put this card, usbs works very slowly. If i disable on bios the Wwan card the usbs work right. I didnt know this. So i think if you need use the sim you need enable on bio and when you finish disable the card.

I feel depressed because I really wanted mine to work and have that paired with an RTX card. The green PCB is trash, the problem i checked and i only found this one on aliexpress. I didnt find another ones on ebay or other shop. I was really looking for this model because it has a power similar to a 4930mx or 4940mx but is 47w and has better integrated graphics. But I really see it as absurd to ask for another one. If there was a way for the seller to test it and tell me that everything works and that's the case, that would be great. But before buying it, I contacted the seller and told him if his had any faults, and he told me no, they worked perfectly. So perfect that they don't turn on...

My 4980HQ arrived 2 days ago. It has been a total disaster. I have not been able to get the bios to recognize it. I tested 2 MQ processors that I had being recognized perfectly when I reset the bios. This 4980HQ was never recognized... I updated the bios to A26 and tried resetting the bios several times. The processor pins were perfect but it didn't work, so I started the return... In the end I have decided which processor I will install and it will be a 4930mx. I will no longer try with 4980HQ, and even more so after reading the number of problems they cause, from display port failures, others that do not work like my case, others that only recognize 1 or 2 ram slots... To clarify, it is the same green PCB in the last photos uploaded here.

That's cool. I saw an I7-4980HQ PGA on Aliexpress and since it has less tdp and seeing that the 4940mx and this one are identical, I think the 4980HQ is better for me. Apart from that its integrated GPU is better although its use will be with a P4000M but having that lower tdp I think it interests me. Then I also really like the idea of the Honeywell PTM7950, and I'll probably make some modifications to the heatsinks of both the CPU and the GPU, and I can gain some extra grade.

How worked this cpu in your dell m6800? All was ok? cpu temps were right or too hot?

Hi. I have a question. Between the 4940MX and the 4980HQ which one could you use on the dell m6800? In terms of performance, the 2 are similar and according to tdp, the 4940MX consumes more, so the 4980HQ should heat up less. In addition, the integrated graphics are superior in the 4980HQ. But I read that it also gets very hot and that maybe the 4940MX is better. I also don't know if the 4980HQ, being another type of adapted GPU, would cause any compatibility problems. So I want to know what opinion you have about the choice of 1 of these 2. I forgot to say something important, but the idea is that as the main graphic I am going to use a P4000M.
