For example, I use an Nvidia A400 at work. You could install that as well. Or Intel Arc cards. Depending on the available power, you can install many different cards. So all the major manufacturers—Nvidia, AMD, or Intel... The power target shouldn't be too high. Over 500W. But I think it’s clear to everyone that 500W is excessive for a laptop! 300–400W is more than enough to outperform today’s latest gaming laptops 🙂

That's right—that's how it's all set up. This allows you to use the laptop's existing cables, so you don't have to worry about that.... It might be hard to see from above, but there are two rows. That means, depending on the GPU's performance level, you can connect two cables and utilize the full GPU power of the P870xx—up to 450W!

No, these are just the latest parts and versions! I'm still working on the cables, etc.

My latest boards for second CPU control for all P870xx models!

My newest sets: MXM- and Powerboard

Since I do everything myself and currently have less time, everything is taking a little longer. I would like to have the cables ready by the end of the month. Everything else is still in progress. As I said, I'm not a big company with a huge budget. I develop as I have money and time.

Yes, I developed everything with my CAD programs! It's not all finished yet, but yes, that's how I develop!

I would say I'm taking it step by step! Right now, I'm developing the cables with Flex-PCB!

Take a look at the pictures to see what the RTX5070Ti desktop looks like in the P870xx. Then you'll know that my solution of using two different graphics cards, MXM and a normal desktop card, won't work!!!! It's either one or the other!!!

However, the standard MXM specification is acceptable, but the Clevo format is not compatible. Only other manufacturers are compatible, but the question then arises as to how compatible the pins are with the motherboard.

No GTX1080 from Clevo will fit in there. That said, I would recommend the RTX3070 or something similar! Unfortunately, there is so little space that only other manufacturers are using new graphics chips! I don't have any good ideas yet...

I'll let you know when I'm ready! :-) Well, you can't do much with that...

I can only agree with some of the previous speakers. Unfortunately, genuine DTRs are completely extinct these days. This has mainly to do with Nvidia's contracts. I know from reliable sources that they want to control everything and only tolerate soldered variants, especially for laptops. The only exception Nvidia makes is for industrial devices and military technology. Clevo was really the last major milestone in terms of BIOS and MXM standards. I had the ideas for my P870xx projects years ago because Clevo was still doing real high-end development with the greatest possible flexibility. I would like to thank the people in the forum for their support. I hope my desktop extension will be fully operational soon.

Hi, this is what the RTX5070Ti looks like in the P870xx! I've now measured all the lengths and will be able to make the cables soon... I'll do the routing soon, I mean! best regards

Hi, I took apart the RTX5070Ti to measure the DisplayPort cables. On the PCB, you can clearly see how the DisplayPort channels are routed, and the manufacturers pay close attention to the routing of the channels! The chip also looks like new! Thanks again to Darius!

I'm also testing G-Sync for desktop cards. I took this possibility into account when developing my MXM board. I'll get back to you on this topic.

Hello Darius, Thank you very much again for your help with the graphics card. It has now arrived and looks like new!!! Now I can build it in peace and implement this card in the P870xx. 1. I'll measure the PCB for the DisplayPort channels and route the cables. 2. Design the brackets for the card. 3. Develop cooling—water or vapor chamber. Let's see what ideas I come up with. Best regards, Ralf

Hi, Many thanks to Darius. I'll pick up the card on Monday and continue building and developing. The first small subproject is the internal and external cable so that an internal display and an external display can be connected. I've already developed the schematic and, with Darius's help, I can now determine the exact length of the FlexPCB and start routing once I know the exact geometric ratios. The cables should work for all future generations. The second project will be the cooling system. In the short term, it will be water cooling, but there is also the option of making a vapor chamber like the original. However, I don't know the exact costs for that yet. That's all from me for now. Thanks for your support.

You can only try it out and use trial and error! To be honest, I don't really understand the need for Gsync. It's supposed to be a synchronization technology, but I think that if the graphics card, display, and CPU are good, this technology isn't really necessary. Sure, you can talk about personal preferences, but I think that's all it is!

Hi maro, just use the latest WQHL driver. That should do the trick!

Yes, this card is perfectly made. Although the other cards are also good. But this card is geometrically well done.

Hi everyone, I have some great news for my Desktop-GFX project! This graphics card from MSI is the perfect fit for the P870xx. The card is called MSI GeForce RTX 5070 Ti Ventus 3X PZ! Other cards also work very well, but this one is a perfect fit.

That's my development, and there's more! 🙂 Maro gave you tips... Greetz..

I would also be interested in this method! The method I use probably interferes the least with the BIOS without changing too many things.

In the picture, I have once again highlighted where I made the most important change to the MXM board! In case that wasn't clear enough. The DisplayPort lanes must be routed accurately!
