Now it´s Clevo not ZBOOK G6/G5 ? Ok remember please i was write in my previous contribution (there are several pins call OEM ,RSVD and maybe more) is important this means not only the OEM pins in this case. You must be better attention of these diagrams.

This is one of many problems too on M18x by the way. Good luck to modify.

Hello. I looked at your post yesterday. I was curious why you did this. So I tried to discover.

 

I compared very carefully each pins one by one, between my MXM connector and the RTX 4060 pins from ZRT.

 

Here you can see that everything coloured is 100% compatible with my MXM connector.

 

The red crossed ones aren't compatible signals for my MXM connector.

 

JTAG is for testing, so I don't think that's important for eDP.

 

Although the pins 240 and 242 seem important because they are like the "footer pins" of the DP_D (eDP).

 

Are the two 3V3 pins that important?

 

If yes, that's why did you do the wiring to power some of the 3V3 "signals" back? On my MXM connector, the two pins are set in RSVD.

 

Can the manufacturer do some custom wiring for me? Like "cross-wiring" the pin 240, 242 to pins 278 and 280 for the 3V3 "signals"? Or get the 3V3 somewhere else on the board? 

 

If no, then nothing to worry about them?

Thanks 🙏 @SuperMG for your updates 

I will waiting your opinion for upgrading my p870 to ZRT 4090 . 

“As for whether it is compatible or not

It's genuine MXM so 3.3V is mandatory, but you have it on the last pins.

As you can see on adlink AD5000 mxm, many pins are N/A (non applicable so non wired).

There are 4 DP lines but absolutely NO edp wired.

Most probably your RTX4k series are non wired either.

Turing & Ampere mxm cards don't have EDP wired either... That's why standard MXM RTX 3000 has to use OPTIMUS, whereas HP RTX can bring signal to edp screen.

If you look at the Intel Xe mxm pinout, you may see LVDS crossed (so most probably N/A) and EDP_D pins.

The pdf you gave the DP_D is DP. It could work with eDP but you have to mod to bring the brightness. Without mods, eDP doesn't work for the cards in the pdf.

 

The RTX 4050/4060 from ZRT have eDP on port D but my lap doesn't have the 3V3 power for the pin 240 and 242

Why are the LVDS and VGA pins on RSVD or N/A?

Hello.

 

X-vsion sent me their schematics and the the pins from 170 to 280 are the same as ZRT, they both have the same signals...

 

But the x-vsion eDP doesn't work on both of my laptops.

Hi, good work on this . The RSVD pins are a reserved pins for additional equipment of electronics on GPU board, and thru these pins (3,3v)  powering them in this case. Manufacturer strictly directions use of them, but not always at the same positions 240, 242 it can be on different pins like 235, 237 and so on. On some time ago i was trying to solve similar upgrade problem on Clevo P177SMA. The result is yes this pins are important ,but modification is not necesesary to be done on mxm side. The connection brigde it can be done on GPU board too. It´s nice to see how much people are interested about this problems and trying it to solved in. Thanks for your help, everyone.  Let´s go and never give up.

ZRT told me these pins are for "IO ports", didn't specify me which ones.

 

And ZRT said they tested eDP on port D with normal DP...

Yes it´s true, but don´t forget please to a Dual Link-Mode of DP-out .

Yeah but your card has DP. ZRT has eDP, that's different.

 

You might buy the RTX 5000 from HP because it has eDP

I did look between my mxm connector and the ZRT 4060 signals and I again found something.

 

Are the pins 23, 25 and 27 important? Because on the ZRT RTX 4060 they are all in N/A

 

On my connector it's all PNL_ signals. (Like PNL_BL_EN)

 

Like does PNL_BL_PWM mean Panel Back Light PWN? Because X-VSION and ZRT are lacking it

 

What are these? Modulation clocks?

 

 

 

 

Some news: ZRT told me their Quadro A2000M and RTX 3050M are eDP compatible like the 4050/4060/4070... but on their specs, I see DP 1.4+, not eDP. Kinda strange no?

it's panel Backlight PWM, should PWM is used on the LCD (quite seldom, unless it's OLED display)

Hello.

 

I compared the AETINA GTX 1060/1070 schematics and my MXM connector schematics.

 

They both have the

 

PNL_BL_EN

PNL_PWR_EN

PNL_BL_PWM

 

But on the ZRT/X-VSION cards they have them set to N/A.

 

Why? I'm sure they are needed. I looked at my eDP connector and I see the PANEL signals. (_EN and _PWM signals)

 

[SuperMG]

MXM connector pins (not the eDP conn) the same as P570WM, P870, Zbook G5/G6 17

Good point. These pins are important.
PNL_PWR _EN - enabling power source to LCD 
PNL_BL_EN - on/off LCD
PNL_BL_PWM - pwm duty cycle 
I think there isn´t nothing terrible to solve it. The first and second maybe will be a TTL logic so level high it is needed  (1.8v-3.3v). PNL_BL_PWM - first i try 3.3v = 100% duty cycle

Thanks.

 

I asked ZRT if they can enable them. They did use these pins on their GTX 1070M and 1660TiM (even thought they don't have eDP)..

 

Here's where the pins are relied on my eDP conn.

 

PNL_PWR_EN for pin PLVDD

 

PNL_BL_PWM for pin PNL_BKLPWM

 

PNL_BL_EN for pin PANEL_EN
