@SuperMGJust saw that XVSION has made an RTX 3050 6gb MXM a card. Wonder if it will work on my zbook 15 g2-atleast in hybrid mode?(I think the eDP is on C in the 15 g2). As I've heard, only up to turing cards would work. Will there at least be a modified vbios for a DP_C output?

Hi, yes the card will work in hybride mod, you'll loose a little bit of performance due to routing the display signal through the iGPU.

 

I used a 1060M that had HDMi on DP_D (laptop booted with black screen in discrete GPU mode, booted fine in hybride mode and 1060M was recognized and used for games)

 

Not sure the external display outputs will all work well, we'll have to look up the schematic of your model to make sure wich external display connections have a mux switch meaning the iGPU will run the external connections as well.

Precision M6700 : i7-3740QM | M3000M 4gb +250mhz OC vbios | 20gb DDR3 | FHD ips dreamcolor | delta fans

Zbook 17 g3 : i7-6820HQ -75mv | P3000 6gb modded imac vbios | 16gb DDR4 | FHD ips 

Precision 7720 : i7-6820HQ | GTX1060 6gb, 88w OC vbios | 16gb DDR4 | (crappy) FHD ips

Zbook 17 g5 : i7-8850H, -140mv | P5200 16gb | 32gb DDR4 | FHD IPS -> attempting 4K120hz upgrade

Has anyone done this for a X170, was debating grabbing a 4090 card but the heatsink comments have me out of depth on this. 

Not yet. But yes the heatsink needs to be modified. RTX 4070, 4080, 4090 worked on the P775TM. For 4080/4090, ZRT/Enbik are prefered brands because of their VBIOS (DP/DP/HDMI/eDP, enabled eDP and not disabled eDP, otherwise blackscreen after drivers installation)

Thanks for the reply, i would have no idea how to modify the heatsink unfortunatley.

Hello. I still have some backlight eDP mod cable available. Available on ebay. Support would be helpful.

 

The mod won't work on Dell M6700 with Dreamcolor LVDS display. eDP to LVDS doesn't work because the GPU doesn't understand what screen type it is. I couldn't try on pure-eDP because I can't find the 3D cable
