My GPU expansion does not fit into the X170xx! The geometric proportions alone are unsuitable compared to the P870xx (DM23/KM/TM)! The second aspect is the electrical connection, which is different for the X170xx. My development is specially adapted to the P870xx (DM23/KM/TM)...

Hi, you surely mean the GPU extension! The X170xx has a newer CPU generation, which will be a slight advantage, but my tests with the GPU extension showed almost no difference to the 9th Gen! My GPU extension works with all P870xx, except the P870DMG (the very first model)! Please send me an email for further answers! Greetz

Yes, I played around a bit. Also to test how the card behaves!:-) Thank you for your support

Yes, I think so too! It only works with the new cards... Unless NVidia makes updates for the VBios, but I don't think so!....

Hi Maro, your bios is the limited version! In addition, the bios does not have such support. There was no rBAR yet! That also depends on the bios. The GTX10xx series could possibly also be updated via Nvidia. But I don't know exactly. Greetz:-)

Another new thing I have developed is that the second CPU fan (5V) for the P870TM is properly controlled by the Clevo motherboard. This way the fan is not constantly running at full speed... Below you can see on the left how the fan starts and stops: Links: https://easyupload.io/msof2j https://easyupload.io/aubzj3

Here is a test with Horizon Forbidden West with the RTX4070ti in comparison with a desktop PC and 13700K. The power consumption of the GPU is also astonishing, almost the same! My power supply, in the form of an SSD 2nd hard disk slot, can withstand the load without any problems. All settings are identical. NO FG, DLSS, FSR....

This information does not appear on my P870TM! Strange....

Here another test with Avatar(RTX40xx / Ryzen 9 7950X3D) and RTX4070Ti / 9900KF in P870xx-Board: All settings same!

In addition, the GPU will always be switched off on the P870xx anyway, as this is due to the design and was planned by Clevo! No matter whether 9900KF or 9900KS both work the same in the P870xx motherboard...

Would you do the same test with Wukong using your NEO? So that you can compare the laptop performance! That would be nice:-)

Hi, The simple reason for this is that I don't have another 9900KS to test at the moment! I think the KF will do for now. But I think the comparison clearly shows that the 9900KF / KS is still a very good gaming processor e.g. in comparison with the gaming processor from AMD 5800X3D. I have also compared with 13th/14th Intel Desktop, and it also looks good 🙂 The 9900KS should perhaps work even better. In UHD you can see the real performance. But the comparison also shows that the processors don't make the huge leaps as promised by advertising, at least in gaming! The P870xx in combination with my expansion can keep up well with the latest platforms in terms of gaming. I'm currently still testing 4k/UHD resolutions, something isn't working properly yet. Otherwise, the rest works very well and is stable. I would be really interested to see how the latest RTX50xx generation works in the P870xx:-) Greetz

Hi, here is another test with Cyberpunk 2077 in FHD in the P870xx with RTX4070ti. Average FPS is about 40FPS higher than the latest RTX4080/4090 laptops! But also depends on the game. That should be clear. The electrical power consumption of the GPU is about 250W. So the total power of the GPU runs completely via P870xx motherboard. See picture. All settings in the game are exactly the same! Another Test with new Game black myth: Wukong AMD 7 5800X3D and RTX 4070 Ti

Hi Maro, no, I haven't completed it yet! I'm still doing some tests on the display etc. I have made a new MXM board and am testing the routing. Greetz

Ok

Hi, no, I have now perfected everything concerning the recognition in the bios and the driver installation. Everything as originally made by Clevo:-) The driver only needs to be installed normally, nothing more! Done 🙂 No more Inf-Mod or anything else necessary. The benchmark results of SteelNomad are even done with less power consumption. Only about 80%, i.e. about 260 watts! Greetz

Hi, here is my last test with RTX4080 and P870TM: Bios Screen and Steel Nomad comparison from Computerbase

The vapor chamber must be properly machined with the milling machine. Why didn't you buy the RTX3080? The price is affordable and my adapters work specifically for this series of cards. RTX30xx! The adapter is now in its 3rd version developed by me. They have been working for the P870xx, P775xx, P750xx, X170xx for over 2 years. If you have any questions, you know how to contact me :-) However, every heatsink of the laptops must be processed. Greetz

Hi, I sat down and developed a holder for the GTX10xx-RTX30xx for the P870DMG! Until now, it was always a bit difficult to convert because of the holder of the new generations. Many people have already built their own holder, but always in a special way. Here is my model for printing in 3D. Plastic is perfectly adequate:-) Greetz

See previous mail

So I can repeat it again. The adapters were developed by me and are now in their 3rd version. If you want to know something about it, you can write to me here by e-mail:-) Since the RTX30xx MXM came out, my adapters have been running and I have been constantly improving them.

It is very unlikely that AMD or Intel will do something that Nvidia does not! It has to do with the monetary system. It's about selling laptops that are good for one generation and then in the next generation everyone has to buy new laptops in order to have new laptops. Clevo was the last big manufacturer in the HIGH-END sector. Clevo has also submitted because they are forced by contract. Laptops like the P870xx or X170xx or P775xx were the best examples that it is no problem to develop something like this! There are currently only soldered boards! I can hardly imagine that it will be any different in the medium term. The financial pressure is too great. That was also the reason why I thought the idea of the MXM-PCIe adapter was so cool and developed everything. My electronic kit has been developed so far. I have currently made a 3rd version to test things out. On the whole, however, everything works stably. There are still a few things to test and redesign, but basically it works. Theoretically, the CPU socket with adapter for 13th/14th Gen HX Intel can also be developed. That would be cool, but the 9900K/KS is still good for gaming. Besides, I don't want to venture into such an adventure at the moment, I'd rather finish the MXM-PCIe adapter first:-)

What do you want to do?

Once again for clarification: In order to install the RTX3080/70/60 MXM in the P870xx, the mounting between the heatsink and the graphics card must of course be modified. As everyone now knows, the mounting holes of the RTX30xx MXM are no longer identical to those of the RTX20xx/RTX20xxSuper/GTX10xx/GTX9xx MXM series! I have developed adapters especially for the Vapourchamber which have been working for a good 2 years in the 3 version. Of course, the Vapourchamber must also be machined accordingly with the milling machine. This whole topic motivated me to develop it myself because the Vapourchamber is the best air cooling system for laptops. Of course, the other heatsinks that have come out for the RTX20xx / GTX10xx also work. But with the Vapourchamber, the P870xx is the best cooled laptop ever at maximum gaming performance. Only water cooling is better, of course! Addition: I have now also perfected the bios detection of the RTX30xx series. Many thanks to RUNIX for the tips. You don't have to have it, but it's nice if you know how:-) I can leave a picture to see what the Vapourchamber with 2x RTX3080 in the P870xx looks like. But that was just a test because of SEMI-SLI. Otherwise I only ever install 1x RTX30xx MXM in the P870xx! Greetz:-) Almost 2 years ago is the photo!!!

Can you briefly explain what you mean? I didn't understand your text.
