Does this motherboard support PCI express 2.1?

That’s an older motherboard.Your version of PCI-Express x16 supported isn’t COUPLE OF.1, however that’s very little big work because 2.1 playing cards are entirely backwards-compatible having all before versions belonging to the PCI-E x16 specification on the handset.

The same applies to motherboards- brand new boards with version TWO.1 PCI-E x16 video poker machines work good with old cards.
