I’m looking at quad port 2.5Gbe Intel PCIe cards. These cards seem to be mostly x4 physically (usually PCIe gen 3) whilst I have a PCIe Gen4 X1 slot, which is more the theoretical bandwidth that the card can support. The card needs at the most PCIE Gen 3 X2 == PCIE Gen 4 X1 in terms of bandwidth.

How do I fit the card into a PCIe x1 slot? Won’t it lose performance if all the pins are not connected to the physical PCIe connector? Is there a PCIe x1 riser that the community likes that is somewhat affordable?

Thanks

    You can probably use it, but you will not get full throughput on all the ports at the same time. 3.5/6 max real world.

    My advice, get a cheap pcie4 10g nic and a 10g switch with multiple ports, but idk what you’re trying to do.
