By a little (2mm) Don't worry it'll work as I have an a5500 + R4 ready for the next week

There's always a solution for everything (unless we're talking about Nvidia vbios modding, it's impossible:/). You can do: Custom heatsinks, custom mxm holding, etc.

Or get the Quadro RTX A4000 for 350€. 16GB VRAM, RTX 3070 level. It's a DP/HDMI/HDMI/DP card. RTX A3000 12GB is 250€ but it's low TDP. (no backlight mod adapter included on both) For the Turing RTX 3000, I don't think there are 12GB modded VBIOS for it.

It's actually better to get an RTX card to work internally. Please find the eDP cable for this laptop or make one by studying the schematics. It's just wires and connectors, no chips in the cables.

Older Aetina cards didn't need 4G decode enabled in the SBIOS. Anything Pascal and above aren't compatible with the LVDS output. It's eDP/DP for internal. Yes if you got your external monitor working with "eDP" on DP_D, it's a good sign that the card displays using the Display Port protocol. If I was you, I'll find the eDP cable for your laptop and then study the output pins of the cable and determine if it can do 1080p, 1440p, 3k, etc...

It makes sense. It happened to me. Without 4G decode or without disabling the legacy OPROM (pure UEFI VBIOS), the GPU won't post and the laptop will throw an error and stay stuck in the pre-post. Aetina can sell individual but the price is very expensive and you need a SBIOS with 4G decode to use them. ZRT, X-VSION, ENBIK sells to individual, sadly their RTX 4080 and RTX 4090 have eDP in port D but it's disabled once the drivers are loaded. Only way is to override the EDID. Another way (which seems impossible from now), it's to find a VBIOS that has eDP enabled and doesn't disable once the drivers are loaded. The best cards without any issues are RTX 4070, RTX 3080, RTX A5000 (needs testing) and A5500 (needs testing) since they have eDP or DP in DP_D and they aren't disabled. Yes DP output works in eDP screen because the HPD data is in DisplayPort protocol.

Okay guys. The 4 heatpipes (2in1) heatsink for the M17X R4 has been shipped and so the backlight mod v2 cables. I'll test the A5500.

As long as the LCD input is an eDP signal then it can work. But it can depend in the dreamcolor boards. Someone needs to try it.

I'm curious. So his GPU has HDMI in DP_D then? If it has simple DP in DP_D, it should have worked. As "eDP" HDP are just DP signals. I think the RTX Turing will work (if all ports are DP/DP++) on the Zbook G3 17. Sadly not with the X-Vsion nor with ZRT cards 😕

Don't use Optimus and LVDS. No one has tried pure dGPU in eDP with a MSI and a new RTX MXM. Maybe this could fix some the issues you mentioned

DP/DP/HDMI/eDP. Same as the RTX 4070 MXM. Works perfectly fine on my M6700 and 7720. I had all the display ports, even the USB-C on the 7720.

I have a Dell Precision M6700 Red Covet with RTX 5000 16GB if you want with the 120Hz 3D screen. No fan problems and the RTX 4070 and 4080 worked in this laptop with the backlight mod.

For Aetina it was the case for their Ampere and Ada cards. Maybe PCP is using the same VBIOS as Aetina? For X-Vsion it's different. I saw the GPU-Z screenshots and the GPU was outputting in DP without 4G decode enabled in the SBIOS.

It's already longer because of the newer design.

Hello everyone! Do you want to upgrade your old laptop MXM GPU? But you can't since the newest RTX Turing, Ampere, Ada and Blackwell won't work with your eDP display? I have the solution for you! No more blackscreens! The backlight mod v2 upgrade to enable eDP display for your MXM card! Here's the old thread for the backlight mod v1: Every cards from Turing to Blackwell generation, from brands like Aetina, Adlink, PNY, ZRT and X-Vsion will work with this mod! Thank you to everyone who bought the backlight mod v1! I have sold everything! The backlight mod v2 will offer BRIGHTNESS CONTROL thru a tiny PWM module that you can install inside your laptop's case or in the SSD/HDD 2.5" bay or directly outside the laptop. (Backside of the PCB is insulated) How to control it? With the small knob, you can directly control the brightness from 1% to 100%! The v1 was stuck at 100% because 95% of the laptops I tested lacked the PWM brightness module in the motherboard. Only the Clevo P570WM3 had brightness control with the v1 mod! The flex FPC cable is longer than before! From 7.5cm to 10.5cm! Why? To allow easier installation! It's now way easier to install the V2 than the V1. Signal 23 and 25 are the same, nothing changed there. Available: in 2 weeks! You can pre-order in my private messages. What's included in the package: 1x FPC cable 1x PWM Module 1x 15cm cable for connecting both For people who already bought the v1, I'll include 2x FPC cables for the same price! Compatible with GPUs: Nvidia RTX 4050, 4060, 4070 MXM-A (ZRT, ENBIK, X-VSION) Nvidia RTX 4080, 4090 MXM-B (ZRT, ENBIK, X-VSION, need EDID override because the drivers disable the eDP, which results to a non-PnP screen in windows) NVIDIA Quadro RTX A5500, A5000, A4500, A4000, A3000, A2000 MXM-A (X-VSION, for Aetina, PCP, you need 4G decode enabled in the SBIOS) Nvidia RTX 3050 Ti, 3060, 3070, 3080, 3080 Ti (X-VSION, ZRT) Nvidia RTX 3000, 4000, 5000 (Aetina, PNY, ADLINK, PCP). Compatible with laptops (v1 tested): - eDP screen (eDP/DP in DP_D port) - Enable pure-UEFI in SBIOS - Legacy Options OFF - Optional 4G Decode enable in SBIOS for Ampère and Ada cards from Aetina, PCP, PNY... (EDP) Dell: Precision M4700 and M6700 Precision M4800 and M6800 Precision 7710 and 7720 (EDP, needs testing) Alienware M17X R4 (120Hz), Alienware 17 R1 (120Hz). Will not work with M17X R3 because the SBIOS doesn't have UEFI and the newer RTX cards must need UEFI in order to display with the DP protocol. (EDP) Clevo: P570WM3, P870 series, P775 series, P770 series, P375SM, X170 series (MXM based laptop and eDP screen but it needs substantial heatsink mod, no one tried on this pc yet) (EDP) HP: ZBOOK G4 17, G5 17, G6 17 MSI: I don't know which models use eDP (probably the Pascal models) but... A lot of users report fan control issues with RTX MXM cards in LVDS Switchable Graphics based systems, so I don't know about their compatibility. Some sneak peek:
