I looked at ZRT side, the eDP is on port D and the HDMI on port E. I don't understand X-VSION specs. There's no way you have eDP on port E!! The vbios clearly has eDP because it shows it on the Nvidia control panel. (I have Quadro RTX 3000 + 4090 as slave) @Maro97if you know how to solder, you can go ahead and do the mods. If you want more explanation on the mod, please send me a private message. Thank you. Edit: the 4080 and 4090 aren't even working with my external HDMI and DP out.... But the RTX 4070 and 3060 worked with DP and HDMI out, strange...

But that's not eDP! It's regular DP on the VBIOS! Although eDP and DP are sharing the same exact 11 signals (without counting the GND) Can a regular DP out with the 23,25,27 pins display on the eDP display? @Developer79

Depends. This one has like 2 HDMI and 2 DP out. The vbios indeed has eDP support but for which port? on D or E?

On eBay there's a cheap P870DM for 380€ but it's shipped in the USA. There's also a P870TM on Leboncoin.fr if you negotiate with the guy, you can get the whole combo (without ram, without GPU, without SSD) for 500€ How did you break your motherboard? Did it also break my 4070 MXM card? Did you hear any sparks? Is it only your MXM port that got damaged? (Bad pins, bend pins?)

Thanks to @Developer79for confirming my hypothesis on the backlight pins. Yes the pin 23, 25, 27 were indeed needed! Sadly Developer79 didn't find a way to do some hardware mods on the PCB of the RTX 4070 MXM. He did it on his MXM connector, which doesn't make the MXM card plug and play on almost any mxm laptops. Although... I'll try my best to solder these 3 pins. The red line is 2 wires. (280 to 23, 25) The green line is 1 wire (278 to 27) If I can't solder these... I need to contact someone else to solder these pins! Wish me luck once I get the 4070 MXM back home!

Hello! What's the max TDP you got? You were thermal throttling? Didn't you use a 1mm shim on the die?

Hello, I have some news... it can work because... Developer79 managed to make a standard RTX 4070 MXM run on his laptop with video driven thru his eDP screen! Yes, the RTX 4070 MXM that wasn't working on my eDP screen, worked on his laptop! Which is a clevo P870. For your information, the P870 and P570 both share the exact same MXM connector pinouts, so it means the card could finally display on my laptop's eDP display! Developer79 did a few hardware modification on the MXM card and the eDP display began displaying from the card itself! So yes, I was right about the backlight panel pins! After, I need to test the card on the P570 but it sure will work 100%. I don't know why X-VSION and ZRT didn't enable these pins? Like... Why add eDP on DP_D if it doesn't fully work in our laptop's internal eDP screen? eDP is widely used on laptops...

News about ZRT... Still no replies! Despite having the MXM card sent to you and you were able to mod it before they even reply. This is wild. I knew ZRT would ghost me because of the laptop support...

I think, they aren't interested in the laptop market! Beside EDP is only used for laptops... Newer laptops don't even have mxm ports anymore. Like Dell, they use some proprietary formats like DGFF...

This could be actually so good!! It means any RTX 4050, 4060, 4070 and even 4080/4090 can have full eDP support? You should make a contract with these companies!

Hello. What's better, the QTJ0 vs the QTJ1 vs the Xeon E-2286M ES (with a proper model number showed on CPU-Z)? The Xeon is clocked at 5Ghz max. QTJ0 at 4.7GHz, overclockable QTJ1 at 4.6Ghz, overclockable All the CPUs can undervolt.

You can't, really can't. I tried that already. You need to mod your MXM GPU and change the power resistors.

That's so cool! If you can make a x8 adapter it'll work on most MXM eDP laptops! Also, we need to make the existing RTX Ada MXM GPUs to work with our eDP laptops! eDP pinouts are present but the MXM cards are missing the backlight pins/jumpers! Developer79 is already working on my RTX 4070 MXM card and will let us know!

No, can work normally

Hello! News so far! Developer79 got my RTX 4070 MXM card! Developer79 will test the card probably tomorrow on his Clevo P870 and tell me what's happening on his side! Will it do a blackscreen and only work thru DP, HDMI? Probably If it does, how @Developer79can trigger the jumpers for the backlight? We'll probably know on this week! About ZRT, still no answers since 5 days!

I never said that. That card works Alienware M18X R2, Clevo P570WM, HP ZBOOK G5 17, G6 17. Could work on P870 series because of it's dual MXM slot.

Hello. The ZRT and X-VSION cards are lacking something than the other pascal and Turing cards don't... Backlight support. When I start my laptop, the backlight doesn't trigger once, which makes the display off and doesn't display anything beside having video signals on DP_D. The Ampère cards on sale don't have eDP on DP_D, they have DP instead but could be transformed back to eDP if you mod. DP and eDP have the same signals on MXM, DP_D_L lines, AUX and HPD. Manufacturers for the Ada, they tested eDP signals with a DP out to an external monitor... I contacted Developer79 and sent my 4070 MXM to him. We'll see if he can simple jump the pin 23 and 25 and make this GPU display on his Clevo P870 (which has the same MXM connector signals as mine).

Hello. I installed a 3080 in the AW18 R1 and the frames were so unstable. Not because of temps, it's because of the weird power throttling to 55W. Like it does 110W then 55W then 110W... On every benchmarks. On the 3060, I didn't see any issues until sliderfra did some proper testing with the RTX 3060. He had the same bug as on the 3080. He didn't found a way to get around the 55W instability bug.

Hello, some following news. ZRT will initiate a meeting about bringing "compatibility to laptops". That's good news, I don't know when I'll get their answers about that. The representative understood my documentations and how we can get these cards to display on our eDP laptops. The VBIOS and the DP_D signals are eDP compatible but as mentioned before, the PANEL pins are N/A on their cards. Panel pins are needed to power on the eDP internal screen. Second news, my RTX 4070 MXM from X-VSION has the same signal datasheet as the ZRT ones but the PCB is different. It doesn't display on my laptop despite the DP_D and vbios being "eDP compatible". I'll send my RTX 4070 to @Developer79, hopefully he can understand the PCB and enable the backlight. He has a P870 as an eDP laptop, this laptop has the same MXM connector pinouts as the P570, so that's good. Special thanks to Developer79 again, Developer79 and ZRT are our only hope to get the newest MXM cards to work on our eDP laptops

Hello I already sent you everything in private message. Also ZRT will initiate a meeting for the pin 23, 25 and 27, maybe hope.

But... On the schematics it's says N/A on 3 of the pins. Pin 25, has a missing component and it's for the PNL_BL_EN. I don't even know if the PWM pin is complete or no, I see some missing components next to it. Pin 23 looks normal I guess? If you're saying everything is normal, then why these type of cards like X-VSION, doesn't work with my eDP display? But the Quadro RTX 3000 from HP works...

Damn, this looks hard. I suppose PWR_SRC is where you get the power from the mobo/PSU connector, correct? Did you also see my picture? Do you see what's wrong with pin 23, 25 and 27?

I mean I buy it for 620USD and ship it to you but you have to ship it back to me if you got the the eDP working on P870TM and any other old laptops with eDP as well. I can pay you a little extra to fix these cards. Are you from Europe? It's my only option if the manufacturer doesn't want to enable these 3 pins back or if they aren't willing to make full eDP compatibility for all laptops.

@Developer79 Hello, if the manufacturer doesn't want to add the components. I wanna buy the card and ship it to you so you can test and probably mod it so it can display on your P870TM. If it works, then it'll work on my laptop too. What do you think?
