I just purchased an IBM Mellanox Connectx-3 Pro (IBM EC38 10GB 00RX859 00RX855 ConnectX-3 Pro CX312B). I am trying to use it in a windows 11 machine with a ryzen 5900x in an MSI MAG B550 motherboard. The card is installed in a slot that is running at x4. The card does not show up in bios or device manager. What might be causing the card to not be detected?
