Specifically referring to motherboard X9DRW -- does the PCI-e 3.0 support PCI-e 1.0 cards?

Thank you for your help.

That's what I think, too. In theory, PCI-e 3.0 should be backwards compatible with PCI-e 1.0, however I'm not able to use a PCI-e 1.0a card in that motherboard. Tried the jumper settings and modified BIOS settings but still nothing.

Thanks anyway.
