Is the third M.2 slot empty? Third M.2 and fifth PCIe slot share the same lanes.

I checked and it can do 4x4, (1x8, 2x4), and (2x4, 1x8). I tried all settings and still only 2 GPUs are shown. Wondering if PCIE5 is just broken. because even with 1 graphics card installed only it that slot. I do not get video.

Hi, try to find if your bios can set to x4x4x4x4 = example https://www.overclock.net/cdn-cgi/image/format=auto,onerror=redirect,width=1920,height=1920,fit=scale-down/https://www.overclock.net/attachments/210919223257-jpg.2525470/

I have a Taichi X570 board, a Ryzen 9 5950X CPU, and 3x RTX 3080's.

2 of the GPUs appear on system info but the 3rd on (PCIE5) does not.

Are there bios setting I need to change to enable the 3rd card? I am not using the NVME sata setting (in bios it said it'd disable PCIE5).

Thanks in advance.
