So I’m running just two NICs in two PCs which are directly connected via QSFP fiber. I was having throughput issues earlier and upon further review of my BIOS, I noticed I had mistakenly plugged my NIC into a slower PCI 2.0 slot.
However, when I moved the card to my 2nd PCI 4.0 slot (1st PCI 4.0 slot is used by a PCI 3.0x8 graphics card), Windows 10 Pro will initially detect the card BUT once I make any change in advanced settings, I get the following error…Also, if I try to uninstall, Device Manager cannot detect the card in the list for me to reinstall it again. It only comes up again if I reboot my machine.
Note I’m on Silver support but sale went thru on 5/6 or 5/7 so might be why I haven’t come up in the system yet - I was told it takes 10 days to show up
