It's interesting because I'm trying to upgrade a Clevo P570WM laptop that has an eDP screen. This PC can be upgraded max to the Turing generation GPU such as Quadro RTX 3000,4000,5000 from HP because it has eDP on port D on the master MXM. And on the MXM slave connector, I have an RTX 4090 MXM. Now what I'm trying to do, make the X-VSION/ZRT RTX 4060/4070 work on this laptop. I looked at the schematics and saw that my mxm connector and the new cards have the same signals for DP_D, which is eDP signal. It's all good but... There's one problem. While comparing the pins, I saw 3 pins that were related to PANEL. 23 PNL_PWR_EN 25 PNL_BL_EN 27 PNL_BL_PWM These pins are for the backlight of the internal screen, so the eDP screen. I suppose without them, I think the screen won't even power on despite having the right video signal on DP_D? Is that correct? The ZRT/X-VSION 4060/4070 have the pins set to N/A, which means blank pins, no signal at all. Does that mean, we have a working eDP signal but no backlight support? Any idea? For reference, I tested the RTX 4070 from X-VSION on my laptop, it won't display anything on the screen but the computer boots to windows. I can connect to DP and HDMI and it displays on external screen. My MXM connector is literally the same as the P870TM1 connector. Ps: I'm also developing a new 175W MXM heatsink for the "centered offset GPUs" so my 4080 and 4090 won't throttle Edited 14 hours ago by SuperMG Link to comment Share on other sites More sharing options...

I can control everything via jumpers on my board! Pins 23/25 are simple jumpers for switching on, and pin 27 is pulse width modulated. However, I found out during my tests that this pin is not necessary. In the picture, you can see how I have taken the PINs into account on my board!

But I can reassure you that an RTX5090 laptop with HX370 is not nearly as fast for gaming as the combination of P870TM 9th and RTX50xx desktop series! I'm still running benchmarks. 1 Link to comment Share on other sites More sharing options...

Greetz Yes but my screen is an eDP display, my Quadro P5200 and Quadro RTX 3000 have these pins I guess, otherwise that's why the RTX 4070 MXM doesn't work. I don't see the screen powering on, on my laptop. However with a compatible card, first the screen backight powers on and then the video signal is out. ZRT saw my messages but didn't even reply... Does the RTX 3080 from clevo have these PANEL pins? Link to comment Share on other sites More sharing options...

ZRT/X-VSION Ampère doesn't even have eDP signals and the PANEL pins but Clevo Ampère does have them... Which means ZRT/X-VSION Ada cards could potentially enable back the PANEL pins so we can finally use these cards on eDP display (P570, P870). I'm still waiting a reply from ZRT because they once told me, they can do some "custom wiring", I'm not sure, but let's wait. Link to comment Share on other sites More sharing options...

The MXM specification has defined these pins!!! Link to comment Share on other sites More sharing options...

You can look up for en.zrt-tech online and look at the RTX 4060 MXM card, you can see the pins. I'm not to sure where to look at the physical pins (front or back of the PCB?, back?).

Yes the DP_D are fixed. I looked and saw 3 pins on the back of the PCB. I hope these are the PANEL pins. They have electrical lines but they are missing some IC and capacitors... I think the lines are here but not connected I suppose? Link to comment Share on other sites More sharing options...

Of course everything is routed. If it's routed, it works! Link to comment Share on other sites More sharing options...
