Is PCI-e 3.0 backwards compatible with PCI-e 1.0? Tags: Support Compatibility Motherboards PCI Express Last response: September 18, 2012 3:33 AM in Motherboards Share ayejig3 September 18, 2012 3:08:26 AM Specifically referring to motherboard X9DRW -- does the PCI-e 3.0 support PCI-e 1.0 cards? Thank you for your help. More about : pci backwards compatible pci unclejehmimah September 18, 2012 3:13:13 AM yes ayejig3 September 18, 2012 3:33:00 AM 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. Can't find your answer ? Ask !
