RTX 3080 in M18xR2? Should I do it? lol

@janepaOkay I found a way to make this file smaller. Here's my eDP connector. It's all for port D.

Ok, but what the other pins of the connector? These pins are´t controlling via mxm card.

You can find the full datasheet online. It's for Clevo P270WM, P570WM3, it's like a 8MB pdf file. This is only the LCD eDP connector.

 

There's no mention of MUX switch on the pdf.

However, I found the MXM connector.

 

eDP is DP_D for my laptop. Yes this is the second part of the connector. The first part I didn't screenshot. It has OEM at pin 41

ZRT confirmed with me that their MXM RTX 4050M and 4060M have the same signals/pins as my laptop's MXM master connector. I compared too and that's also what I see.

 

So you're saying, it'll work with my eDP screen on DP_D?

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.

The ZBOOK G5/G6 potentially has the same MXM connector as the Clevo P570WM. Because all of the Quadro P and RTX from G5/G6 are working with the eDP on my computer.

 

The ZRT Tech said my computer is compatible for their RTX 4050/4060 MXM because they compared their pins/signals with my MXM CONNECTOR. Now I need to order one and I'll see.

 

However Alienware M17X R4 eDP version won't work because the MXM connectors take different signals.

The problem with the m17x r4 is not with the mxm signals, but with the edp mux software control of the ps8321 microchip. Most likely, the laptop cannot recognize the Turing card and newer ones and does not allow output via edp.

I saw the schematic of the MXM connector and it's different than mine. Wonder why most Pascal cards aren't working. 

 

But what does the MUX have? There's no intel HD Graphics for the eDP connector...

 

My laptop allows me to use a Turing HP Quadro RTX 3000, like it really allows me too. I'm sure RTX 5000 will work fine.

So am I understanding this correctly,  the 4090 will work in the M18X R2, but is not in the M17X R4?

[Durabat]

My 3080 build went really smooth, and I have almost everything ready for the 4090 build, if it works.

All will work on Switchable graphics but not in eDP.

 

X-vsion 4090 is like 150W

And ZRT one is 135W

 

You need a better heatsink.

The heatsink I have for the 3080 might work pretty well. It's far more beefy than the stock one, even the 100w variant. As far as the eDP goes, is that why it uses Intel Graphics for display, even when I plug an external display up to it? I was hoping to be able to hook it up to a better display at times, but display adapter is Intel and resolution options maxed out at 1080p@60hz.

 

I thought about attempting a custom resolution and seeing if itd work but haven't had the cance. I figured over displayport it'd do 1440p, but we'll see.

You can't do that on Alienware M18X R2, every output is done thru Intel HD. Meanwhile the Dell Precision M6700 uses the discrete GPU for HDMI out.

I thought that might be the case when I couldn't get it to work. I was hoping for a workaround though. Oh well.

That's the mux switch fault on this board

Thanks for explaining everything. I'm catching up haha.

 

I might have to get a M6700 to play around with too.

I got the RTX 4070 to work with HDMI but my cooling is so weak. If I had tested another vbios while using the M6700 I could also get the DP out work too.
