The RTX 4070 uses the standard MXM layout and X-bracket layout. The A4000 is different, it's not standard MXM layout because of the core offset, which is in the middle. However a standard X-bracket will work on the A4000 like on the RTX 4070. For both layouts, 4070 and A4000, you need some new heatsinks because of their higher TDP and the different MXM layout.

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.

Alienware M17X R4 MXM upgrade for eDP 120Hz.
SuperMG replied to SuperMG's topic in Components & Upgrades
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. -
HP Elitebook 8570W - is it still good ? Hardware modifications
SuperMG replied to GuitarG's topic in Custom Builds
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. -
HP Elitebook 8570W - is it still good ? Hardware modifications
SuperMG replied to GuitarG's topic in Custom Builds
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.
