GPU issues with PCIE x1 to x16 Riser.

[Nimbo420]

Ok so I'm trying to hook up a 2nd GPU via PCIE x1 to PCIE x16 riser. When Either GPU is plugged directly into the board x16 slot they work and mine fine. When I add the additional card (one card in board x16 and one connected to riser) I cant get display connecting to the x16 card but I can get display from the riser card. But then when I try to mine it cant find my GPU's. and will only mine via CPU (xmr stak win64). Both cards show up in the device manager but with exclamation error. I have tried clearing the drivers and reinstalling them multiple times with each card connected directly to x16 slot and I'm still having issues..


I have a XFX Radeon RX 460 4gb and an ASUS OC Radeon RX 560 4gb

(I'VE SPENT HOURS ON THIS PLEASE SAVE ME)
