I've rebuilt my music pc with the Z87 HD3 mobo and i7 4770 cpu. Everything was installed fine but when I tried to install a Lycom Firewire card into one of the PCIe x 1 slots but it didn't appear to work. I tried the other slot but still no response so I tried the x16 slot and this time it worked.
But I've now got a Lycom USB 3.0 expansion card as I need more USB ports for my instruments and again tried to install the card in the PCIe x1 slots and again they didn't recognise the expansion card. I don't believe the cards are broken as they work in the standard PCIe x16 but I can't believe the slots are broken too as the board is generally working fine.
Do I need to enable something in the BIOS to get these slots active or do I need to do something else before I return it to the seller?
Any help gratefully received.
Terry
