Summering: Didn't work in my new PCs. Vendor said it only works in motherboards with older pci-e standard. That explains why it didn't have a yotta mark. They were good about accepting a return though. Later I bought Intel I340-T4 which worked fine.

Summering: Card is not recognized by none of the latest motherboards from ASUS and Intel. When cable is plugged in only one port light was showing LINK light. Other 3 ports were dark. Driver installation fails with message: No network card detected. (or something like that).
Summering: I had to return this item because it was not compatible with my motherboard. The EXPI9404PT is a PCIE 1.0 adapter, EXPI9404PTL is a PCIE 1.0 AND 1.0 ADAPTER. The seller was very helpful in identifying a more modern card as this may not work on newer motherboards.
