Status report on the RTX 4090 (X-Vsion model)

Boot test conducted on the P570WM: A Quadro P5000 was installed as the master and the RTX 4090 as the slave. Although the system booted, the card was not recognized in the BIOS or Device Manager.

Boot test conducted on the P775TM1-G:
The system booted, but the screen remained black.

The modified heatsink and FPC cable required for use with the P570WM could not be used, as they are currently located at a warehouse on the mainland.

You need to use them. It was obvious you'll get a black screen.
