Hi,
I use my Quadro RTX 4000 into an X10SRG-F motherboard.
The OS (Unraid Linux 5.15 kernel) doesn’t detect the card when PCI-e is set into x16. So I’ve set the PCI-e to x8 and after boot, my card is finally detected.
I did a test and replace my GPU with a GTX 1080 and set the PCI-e to x16. After boot, my card is detected. So my PCI-e slot isn’t damaged.
I checked my card with another board (and OS), and it does run with 16 lanes. So the card is functionnal.
I must mention that on my server MB, the OS boots with UEFI, Intel Virtualisation / Vt-d / ACPI / ASPM / x2apic are active, and the PCI-e can only boot with an EFI ROM. I’ve set now the power profile to “performance”.
I tried to set my MB in “Legacy/BIOS mode”, enabling CSM, disabling Vt-d, expect legacy ROM from PCI-e devices etc… But it didn’t work.
The only differences when the PCI-e is set to x8 or x16 is that the PCI-e seems to be “jumped” at the syslinux sequence as we can see in the syslogs files provided.

My MB’s firmware is up-to-date, so I’d like to know if I need to insert some parameters to the syslinux sequence or if a config onto my motherboard need to be set to get my GPU detected with x16 lanes.
Thank you,
