I'll not run it on Alienware. It'll go on Clevo p570, had no issues with 4080 115W power limited thru Nvidia inspector.

 

The 4090 I got is a 115W one and doesn't have any capacitors lying around the x-bracket's zone. 

 

The 4070 I have, doesn't have eDP. It doesn't work on M17X R4 and Clevo P570wm eDP displays. 4080/4090 have the connector present on the Nvidia control panel but they don't have eDP.

Have you actually tried to run 4080/4090 though? Each gpu is different and vbios is different. a vbios alone makes the difference of gpu working or not. 

 

I tried Aetina GTX 1080 in P570WM but it was too long. I'm running 880M right now and have a P4200 that needs bios chip soldered to use that.

I think M17xR4 needs DP_C to be eDP not DP_D. This is why it's not working (speculations of course)

4070 is probably DP_D. What about the HP 8770W/8570W/Zbook G2 at? Are they DP_C too?

 

I tried the 4080 too on my Clevo eDP, it didn't work for the internal display. On Alienware it does the 8 beeps

I don't know about HP. 

 

You can also try 4090 in P570WM. There's a extra vbios uploaded here (150w) model that you can try on your 4090 too to see if it boots.

Bios from ZRT? I'll receive the 4090 X-Vsion in a week. Are the DP_ from the VBIOS or are they hardcoded to the hardware ?

It;s a mix of the two. Normally vbios alone can change the output.

Does someone have different 4070/4080/4090 VBIOS from like Aetina, ZRT?

Hello, how do I know which is DP_C, DP_D?? The 4080 from X-VISION has eDP port declared but the seller says card doesn't do eDP.
