Did you try using a standard MXM card like a GTX 1070 to see if it works on eDP? Although our MXM connectors aren't the same because I don't even have the mention of MUX for DP_B and DP_A. But they seem to be on the same lanes. And although, my Quadro RTX 3000 works on eDP and also displays thru DP, HDMI easily. Link to comment Share on other sites More sharing options...

I have tried with a GTX 1070 without power cable from a Eurocom Tornado F5 and it worked. Thats an MXM3.0 and I think it is MSI.

Maro97 Posted August 14 Author Share Posted August 14 36 minutes ago, Kastner said: Yes. Aha this mxm model supports from 115 to 120w pwr limit so the p870tm mxm slot can handle 120w without laptop gpu pwr cable. But rtx 4090 mxm is 150w . So i wonder if P870tm mxm slot can handle 150w without 8 pin gpu cable ? Link to comment Share on other sites More sharing options...

Held back a bit do to CPU bottleneck ( QTJ1 ) but in some games I've seen it spike to 200 . It's a custom mining card I think his card has no power cable so it can support up to 200w. 1 Clevo P870DM2 9700k RTX3080 Clevo P775TM1 9400F GTX1080 Link to comment Share on other sites More sharing options...

I have no idea what these pins are for? Are they for the DP_D? For the JTAG signals? Who knows... Link to comment Share on other sites More sharing options...
