I'm running a 470, 480, 570 and vega 56 all on the same rig. I just installed the blockchain driver. Perhaps you have a riser problem.
I used the blockchain driver. what did u exactly do ? I installed vega first then tried 570 first. i tried both on pcie 16 on mobo. no luck.
the same things I experienced. I started to check on the motherboard, PCIe USB raiser, Driver and type windows. I use window 10. then Problem was Solved
which version of windows 10 u using ? Im using windows 10 fall creators update.
Used that too. no difference.
