Hi, i am looking at the NIC as above which is 4P 25Gbps
It states that it is spec as PCIE 4.0 x16 and it is physically as such as well

If i were to slot this into a PCIE slot which is physically x16 in length, but had a bandwidth of PCIE 4.0 x8, would it be detected and useable ?

I should think it does since PCIE 4.0 x8 has a theoretical max bandwidth of 16GB/s or 128Gbps

Hi Gordon-Teo,

Thank you for posting in Intel Ethernet Communities.

Regarding your inquiry about E810-XXVDA4, the maximum slots for PCIe 4.0 is x16. Therefore usage of PCIe 4.0 x8 is detectable and compatible with this product as long as you are using PCIe 4.0.
