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
Pretty sure if you put a PCIe 3.0 card in a 4.0 slot the slot will drop to 3.0, and 1 PCIe 3.0 lane probably isn’t going to work great with a card meant for 4 of them.
The card only needs PCIE Gen 3 X2 == PCIE Gen 4 X1 in terms of bandwidth. I was hoping to fit it into the slot since it meets the bandwidth requirements
An x1 slot is an x1 slot, the PCIe version will downgrade but there will still only be one lane because that’s all the slot physically has connections for. It will effectively be a PCIe 3.0 x1 slot.
Technically the slot is PCIe Gen 4 x1, but I understand. TBH PCIe gen 3 X1 is fine too, that’s more than 6 port Gigabit cards can saturate anyway.
