Hi all

I have a Dell T20 server and I have just bought another NIC that I'm going to install. Looking at the lane setup in the manual page 45, I don't know if there would be any detriment to installing the NIC in slot 4 which is connected to the PCH rather than in slot 1 which is connected to processor at x16.

FWIW, CPU is Xeon E3-1225 v3. NIC is Intel EXPI9402PTBLK and seems as though it can operate at full bandwidth on a x4 lane.

If there's not going to be any any performance dropoff using the lane connected to PCH, I would rather use this to save the full bandwidth lane for something else down the line (if required).

Any advice gratefully received :)

Dual port 1GE card, can live fine in a PCH slot.

If someone is curious about a quad port 1GBe or dual port 10GBe, how do they determine this?

You look at the number of PCIe lanes, the generation of PCIe and the bandwidth per lane. -- https://en.wikipedia.org/wiki/PCI_Express#History_and_revisions And remember that chart is is megaBYTES -- capital "B" ...
