I am in need of some info pertaining to the RX580 and if it can run on a PCI-E 2.0 X16 bus. I have Adrenaline 18.81 installed and installed the card but it would not return video output. The fans started and all. FX6300, 24 gig 1866 ram, RX580, msi 970 gaming mobo.
Yes, PCIe versions are backwards compatible.
