Im pretty sure the PCIE lanes to the CPU remains the same at 20 lanes but you can get more via chipset (albeit, slower and shared) 

 

Still, looking forward to how this ends. Might even sell all my old spare parts to consolidate into a P870 chassis

The CPU uses lanes—16 directly in the case of the 9900KS variant!
Newer models use more. Additionally, the chipset generates even more lanes. This depends on the DMI speed.
As mentioned, newer chipsets offer more lanes. The P870xx uses the same number of lanes for almost all model variants.
In my opinion, the P870xx has enough lanes 🙂

Dear @Developer79 

This is absolutely outstanding work.👍

good luck my friend and we hope you finish the project development soon ..

greetings….

Hi,
I think only later Intel chipsets, starting around the 700–900 series, support more than 16 lanes!!! The older Z370 and earlier models only support 16 lanes. A manufacturer like Clevo could have included automatic detection, but they didn’t. In any case, my board supports the full 16 lanes...which is probably what most people here want 🙂

the z170 has up to 20 pcie lanes . im not sure how many clevo implemented but clearly you got 16 going through the MXMs  and im assuming no issues with nvme  so probably has 20 lanes from the pch

so anyone who really wants to can install it themselves

Hi! How’s the project coming along? Can’t wait for the 'project complete' announcement and for it to finally go on sale for everyone.

I'm still working on developing the cables! I'll be able to tell you more in two weeks.

Looking forward to this . I have an rtx 4070 reference blower card I want to test

Hello everyone… i wonder if anyone in this fourm tested rtx 4090 mxm from ZRT with p870tm laptop ?

Tested X-Vsion and it works. 4070, 4080 and 4090.

 

ZRT's vbios for the 4090 is a fraud. It's just the same vbios as X-Vsion but it's Max-Q edition. The eDP is still set to disabled when we install the drivers.

What about your modded flexible cable ?

Need the cable mod for backlight for these RTX cards.

hello everyone 

what is that ?

looks like a tool to adjust boost limits and power limits similar to flashing a custom bios .

Hello P870 Community,

 

is there anyone out there, that have the bios for P870TM + 3080 handy? I searched the whole forum and other websites, but I can't find the correct bios file.

 

My bios is Dsanke 1.07.16 + EC 1.05.04. with i9 9900kf

 

After I modded my vaporchamber with standard tools like angel grander, standing drilling maschine + 2mm drill + 8mm drill, and for the bracket adapter, I used the old 1080 back bracket and cutted of the "arms" with the M2 thread. Drilled a 2mm hole in all 4 "mini arms" and file down the M2 thread to 1mm as it is a bit to high and would not raise the GPU to the vaporchamber. Then I screw them to the 3080, so they "look" to the GPU-Die. I also used the electric nail file from my wife to make the 2mm hole in the arms a bit more to a oblong hole, so I had a little variable mounting position to meet the old 1080 mounts.

 

I marked the picture with yellow marker where I have made my changes:

 

 

everything is connected to the vaporchamber and should have propper contact after checking 3 times.

Now I "only" need the bios with 3080 support ;-)

 

It would be really nice if someone can send it to me.

 

Best regards

Mike

corrected mistype in bios version

I forgot my bios show the following data with my current bios:

VGA: Unknown

VBIOS Revision: 94.04.46.00.15

VBIOS Build Date: 02/05/21

And after 1 Minute, the FAN's go 100% and 1 more Minute it powers off the Clevo.

 

The seller said the card is from a X170.
