Like the title says. I installed a GPU, everything posts and boots fine. The lights on the Ethernet port are lit up and will stay lit up indefinitely (I assume) if I leave it at the kernel select screen.

But as soon as I load a kernel, the lights go dark. It also is not shown as an active client on my gateway, so it’s not working at all.

I’ve tried lots of commands I’ve found to force it up. It looks to me like the NIC assigned to vmbr0 is correct. Etc. I just can’t get it to work.

If I remove the GPU, it immediately works again. NIC stays up after the kernel loads and I can access the web UI as normal.

    Ok. I’ll check it out.

    Let’s say it is exhausted… what will get me more bandwidth? CPU or mobo…?

    Only other pci-e card in at the moment is 16 line HBA seems to be basically 2 cards sandwiched on one board)…

      Possible something on your motherboard has PCIe lanes that are dedicated to GPU when it’s slotted, otherwise they can be used for other devices?

      For example here’s a post about m.2 slots that, when used, affect the PCI on a particular board. May be worth checking your boards manual to see if there’s something similar.

      https://forums.tomshardware.com/threads/questions-about-a-mb-im-looking-at-asrock-z790-pg-riptide.3787003/

      The answer not only seemed a HUGE disappointment, but a bit baffling. The pdf manual says if you occupy that 5th m.2 slot, which is the Gen 5 one, the Pci-E 1 slot is automatically downgraded to 8x. This I thought would be unacceptable if running a behemoth like the RTX 4090 I eventually plan to get, as it requires a lot of power and bandwidth.

      Try disconnecting everything including the extra board.
