It has only 1 PCI gen2, and the rest are PCI gen1. Only one of the 16x slots is gen2. Could you confirm in which slots a single NIC will work? You can use "lspci -vvv -s 18:00 | grep LinkSta" to see the speeds when its installed. Does a single NIC work in all slots? Does it only work on the Gen2 16x slot? If you put 2 NICS in 2 gen1 slots, do any of them work? Regards, Dave.
