Those diagrams and schematics are probably made for engineers and hide behind NDA 

 

Unless someone knows and shares, it's usually people like us who tinker and probe the traces in the darkness haha

Outside of learning how to do all the vbios VBT magic (which takes time and effort), step below is to get your hands dirty and plunge money down the drain by buying gpus, flashing them and reporting what works in what combination.

No guarantee if it will ever work, it wasn't designed to from factory. Not that this was ever an issue 

Already tried that. 4070 on DP_D, other VBIOSes are bricking the card.

Sad I can't know what port the HP Zbook G5 G6 used because they do share the same potential port with my clevo laptop...

Whether a mxm card works or not is a mixture of compatible firmware (vbios, efi etc) and hardware (traces).
DP_C stands for Display Port "channel C" sooo, if your hardware (laptop) has motherboard traces for channel C and is configured in firmware to do so, it will work with a graphics card that's also channel C DP enabled.

To get it working in M17X R4, you probably need 120Hz screen (eDP cable screen), PEG mode (bypass intel - default for 120Hz), pure UEFI (no CSM - at Maxwell and later cards) and some luck with a card (compatibility).


You can always get a ch341a @1.8v and backup the vbios prior to opening that can of worms (flashing vbios).
Mind you, it's risky and just because you flash "compatible" for your laptop vbios, doesn't mean that the vendor implemented all the traces into the GPU pcb. Also ch341a extracted vbios will be different to gpuz extracted vbios.
 

I can't find any diagrams about HP Zbook G5/G6 if they are using DP_C or I don't know which port. Not even finding my own laptop's diagram too...

Which CPU generation was your 2012 laptop? Just curious if the Turing Gen GPU cards are matched to certain CPU generations. Therfore assume the MXM port isnt a limitation if you can then run Maxwell (original) then Pascal & Turing. I'd love to try a Turing Card in the 8750W however the later cards i think are bigger than the 965/980M's footprint and also i think the LVDS "normal screen" will only run 980 at best.

Found this wiki if of use. Mobile PCI Express Module - Wikipedia

My CPU is a Xeon E5 2690 v2, same level as an i9 9880H.

I believe that is the D version. 

I got the RTX Turing to work on eDP with my laptop from 2012.

I still am confused about the DP_C port...

For example, everyone said Alienware M17X R4 eDP is DP_C. But when I tried the P5200 on it, it doesn't boot and does 8 beeps. On my Clevo it works... So my clevo isn't DP_C? Then what is it? DP_A? DP_B?

Both quadro cards are coming from Zbook G5/G6. Do you know what eDP port do they use?

Kinda...in discrete mode the laptop screen doesn't work, but it outputs to the HDMI port. Might require a vBIOS mod (which I don't wanna risk lol) because the Quadro RTX 5000 I had previously worked with the Laptop screen in discrete mode.

 

Another issue I ran into is that it won't go fullscreen when using HDMI cable. It might be an easy fix (I haven't been back in the laptop modding scene in a long time) but I don't really need that capability for now

Your laptop probably does DP_C output. Because I know that HP Quadro Pascal and Turing have all the eDP port set to DP_C. You need to find a vbios or a way to modify the eDP port to DP_C.

Your 4090 either doesn't have eDP or has it but it's on the DP_D port.

I asked the manufacturer of the RTX 4070 MXM if they can switch the DP_D to DP_C output for the eDP compatibility.

The manufacturer ignored me but did give me a tracking number for the incoming RTX 4090 115W I bought.

If all of the 4060/4070 from X-VISION have eDP on DP_C it would be a big win for most of 2012-2018 laptops. We can have the 4060/4070 display in the internal screen!

EDIT: Manufacturer answered to me and said they can't do it.

HP as the Aetina is fairly rare in the states and doesn't regularly appear on ebay. It shows as being Dell in gpu-z even though I've made no changes to the vbios.

Yes but Aetina doesn't have eDP support due to its VBIOS yes?

The display is from the Intel UHD and the renderer is the 4090 correct?

Could you please also provide us the ZRT 4090 VBIOS please? Thank you.

Hello here's a group about Clevo P570WM compatibility list of MXM Graphics cards.

The Clevo P570WM has two MXM slots. This laptop doesn't have integrated graphics, so no Optimus. Both MXM slots could provide PCIe Gen 3 speeds.

This laptop has two motherboard versions: one that's for LVDS display 60Hz and one that's for eDP display 120Hz (V2.2 of the board).

LVDS display boards can allow from GTX 400M Fermi all the way up to GTX 900M Maxwell but "Beta Sample/Engineering Sample" of Pascal VBIOS cards could work.

eDP display boards can allow from GTX 600M Kepler to RTX Turing with brightness control at 120Hz. eDP display should be on port DP_C.

Yes you heard it, RTX Turing works on this laptop with HP or Dell VBIOS. I tested with an RTX 3000, so other models from the same era should work (T1000, T2000, RTX 4000/5000). I didn't test Aetina, GETEC, ADlink Turing cards. I heard some don't even have eDP.

What about Ampere and Ada MXM cards? It depends on the manufacturer and the VBIOS the card has. I can guarantee you that anything above Pascal won't work on LVDS displays.

Same goes for cards that don't support eDP out on DP_C. 

I tested RTX 4070 MXM from X-VISION. It has eDP but only for the DP_D out. The manufacturer could possibly rewrite the VBIOS thru readable code and make the eDP to DP_C out. Meanwhile, DP and HDMI external outputs were working.

But there's a workaround to make newer cards to work on Clevo P570WM while using the laptop's display.

Use the master MXM slot as display.

LVDS: Maxwell for master (best is GTX 980 or M5000M)

eDP: Pascal or Turing for master (best is Quadro P5200 or Quadro RTX 5000)

Use the secondary MXM slot as renderer.

RTX 3060/3070/3080/4060/4070/4080/4090 for slave.

I would recommend a card that's below 115W TDP because the original heatsink won't handle anything above the mentioned TDP.

You need to do some workarounds in the Windows registry to make the slave's card the main DirectX and OpenGL card.

The drivers should be at the same version. There are no FPS limits unlike on Alienware M18X R2/M17X R4 with the Intel HD that's capping everything at 60FPS max.

For AMD cards, I haven't tested anything on the first master slot. I only tested an HD 8970M which worked on eDP.

Yes, it worked, but it is currently not in my device

Hello. I tested an RTX 3000 on my laptop and it worked. any RTX 3000 with HP/Dell bios works on eDP. So it means RTX 4000 and 5000 will work for my laptop.

Is the RTX 3000 HP DP_C? Correct? The 4070 from X-VISION is DP_D. I got no display from it other than external outputs.

Hello, how do I know which is DP_C, DP_D?? The 4080 from X-VISION has eDP port declared but the seller says card doesn't do eDP.

Does someone have different 4070/4080/4090 VBIOS from like Aetina, ZRT?

I don't know about HP. 

 

You can also try 4090 in P570WM. There's a extra vbios uploaded here (150w) model that you can try on your 4090 too to see if it boots. 

Bios from ZRT? I'll receive the 4090 X-Vsion in a week. Are the DP_ from the VBIOS or are they hardcoded to the hardware ?

1 hour ago, ssj92 said:

Have you actually tried to run 4080/4090 though? Each gpu is different and vbios is different. a vbios alone makes the difference of gpu working or not. 

 

I tried Aetina GTX 1080 in P570WM but it was too long. I'm running 880M right now and have a P4200 that needs bios chip soldered to use that. 

 

  

 

I think M17xR4 needs DP_C to be eDP not DP_D. This is why it's not working (speculations of course) 

4070 is probably DP_D. What about the HP 8770W/8570W/Zbook G2 at? Are they DP_C too?

I tried the 4080 too on my Clevo eDP, it didn't work for the internal display. On Alienware it does the 8 beeps

ZRT have an eDP support ? I see eDP in display features 

 

 

 

The 4070 I bought had also "eDP" written but it didn't work as said. On Alienware eDP and Clevo eDP. Would probably have the same results on Dreamcolor displays.

Please keep in mind, that mechanic and termal fit maybe it be only a first step to sucefully run 4090 on R2 and then there is a performance issue actually as i said.

I'll not run it on Alienware. It'll go on Clevo p570, had no issues with 4080 115W power limited thru Nvidia inspector.

The 4090 I got is a 115W one and doesn't have any capacitors lying around the x-bracket's zone. 

The 4070 I have, doesn't have eDP. It doesn't work on M17X R4 and Clevo P570wm eDP displays. 4080/4090 have the connector present on the Nvidia control panel but they don't have eDP.

Hi

 

Yes, fits well on the bottom . No stick out issue, but it must use longer bolts and any kind of nuts.

Actually you have the first commercial version. I'll get the newest one without the x-bracket issue. Look at their new pictures now

Or maybye use another gpu manufacturer like ZRT it seems that use a stanard bracket i think.

 

 

Yes, it´s only one possible option ,but assembling will be much difficult i think. Pay atention about diameter and lenght, less diameterr and longer pipe = less wattage transfer

I already bought from them a 4090 115W. Thanks for mentioning the X-BRACKET layout. I told them to give me the right one!

I'll ask x-vision for a custom bracket. Surely they have one, how did they test the GPU then?

I want to pass all the heatpipes on the bottom of the CPU socket. (front view of the motherboard). Then Connect the heatpipes to the copper plate of the GPU2.

wonder. Dunno about Dreamcolor cable, but while I was figuring out pin outs, I learnt there are at least two ways to drive brightness control in eDP screens: using AUX channel or PWM output from board. 
I think Aetina may not have it implemented, though. It is advertised for PC boards, no ?

So you're telling me, HP cards are superior in terms of eDP? My screen is pure-eDP, 120Hz, will all the RTX Turing from HP work?

@nforce4maxyou also said you got an RTX Turing card to work on your M6800 with eDP with an HP card. Which version? C, D?

I saw that ADlink, GETEC, Pny and Aetina are all sharing the same ID of 1F76. So the VBIOS are all the same? And I can crossflash them for testing? I just want to get a very recent card for my eDP laptop. Currently slot one is running a P5200 and slot two is running a 4080

Just now, Myro said:

Cannot say about all of them, but Aetina RTX3000 has eDP output, however the brightness control on 8570w is broken - stuck at minimum level

So it works on your laptop? What ID does AETINA uses? Same as GETEC? 1F76?

The first gen RTX series works with EDP and had zero issues with my M6800 aside from needing to mod the heatsink so there is a chance it could work with your M6600. This card doesn't dump too much heat so it should be fine once everything is installed right.

Which version do you have? HP Or Aetina?

Ps: he has the HP one.

But which vbios version do you have?

Can I flash an HP VBIOS to an Aetina card? It's to use it as eDP on a Clevo 120Hz screen.

These cards don't have eDP support. Even tho on the Nvidia controller panel it shows the "EDP" port but it won't work with my eDP display from 2012.

Do the AETINA RTX Turing cards have eDP lines or not?

On 7/4/2025 at 10:50 AM, GuitarG said:

Quadro T1000/T2000 or any RTX 3000-5000 will work. Tried few vBIOS on mine, all worked with differences being what ports it outputs, for ex. some vBIOS didn't worked with my Displayport. They also different with TDP, Mhz min and max parameters.

I would love to borrow Ampere gen card and check if it would work.

Hello. So it means all the Turing cards can output to eDP screen on your laptop?

HP, Dell VBIOS too?
