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

    In terms of physical connections you’ve said that the card needs the x4. Not sure what there is to say further.

    Can’t get a 30 cm ruler into a 15 cm pencil case.

    Maybe I’ve totally misunderstood your post.

      This is false when it comes to me to PCIe, as mentioned elsewhere in this thread.

      Most motherboards have cutouts on one end of the PCIe x1/x4 slots, for exactly this situation. If not, and you want to be adventurous, you can cut the plastic of the slot and it’ll work fine.

      If the card is PCIe 3.0 x4, and the slot is PCIe 4.0 x1, the card will run at PCIe 3.0 x1. But it’ll work.
