Finally the new RTX MXM cards will work in our laptops!

[SuperMG]

Flex FPC cable mod works on Dell Precision 7720 with an RTX 4070 and 4080.

 

Sleep mode works, brightness control doesn't work on this motherboard.

I'm gonna manufacture some P870 T heatsinks for the new RTX "center offset cards". So the 3080, 3080 Ti, A4500, 4080 and 4090 would work because I wanted to try the 4080 but it doesn't fit

Yes, the 4080 and 4090 work, I tested with an OEM P570WM heatsink + Noctua 12cm 5V USB fan.

 

As we know, 4070 works on clevo P870 with the drivers, with the backlight mod.

 

I did a discovery about the X-VSION's 4080 and 4090.

 

Black screen at the end of the installation of the drivers!!

 

I then took my instructions and did the "EDID manipulation with CRU".

 

After that, I got a display with the drivers installed, no problems. I can even reboot without having to set for a startup and shutdown scripts!! Sleep and savings mode work!

 

So for my P570WM3, I have to do the EDID manipulation then set the scripts

 

For my P870, "only one time" EDID manipulation and then install the display.

No need to do the extra steps.

 

Very strange that the 4070 works fine with eDP but for the X-VSION's 4080/4090, you have to take some "extra steps" despite being a newer eDP display...

 

I'll try and get a 1440p 120Hz display and a 40pin cable for the P870 and see if I need to do the extra steps or not.

 

Yes these cards work great on the laptop.

Would this work in a Clevo P775DM3-G ? 

i got the dsanke BIOS from the TM1 1.07.29 with a 8700k CPU and this LCD: AUO B173HAN03.1 (g-sync working)

 

@SuperMG you should sell the cable on tindie so we could purchase it more easily 🙂

Yes, it works on P570WM3, P870KM, Dell Precision 7720.

 

So of course it'll work for you. Since you have an eDP system, it'll work easily. You have a 4k screen? You might have a HBR2 display so it'll work, just try.

[joluke]

It's not a 4k display. 1080p at 144hz with gsync working. BTW do you know any stores that sell gpu's besides ebay? Can't seem to find any reliable ones 

[joluke]

Anyone can share reliable stores to buy rtx mxm Nvidia gpu's from? Don't wanna be scammed on ebay
