Hi All,

I bought MSI RX 470 graphics card. I am using Ashrock H81 motherboard with win 10 64 pro. I installed latest AMD drivers. When I plug this graphic card directly on motherboard in PCIE-16, then its working. But if I use the PCIE risers, then its not working. Risers are working properly, as other gpus working on it.
My Scenario:

I am using 5 X RX 470 cards on the motherboard and these working perfectly. I tried to add Rx 570 as a 6th gpu, then 570 doesnt detect. But If I install the 570 directly on MOBO, then its detecting. When I tried to install via risers, then its not working.

Do I need to do something on the motherboard or there is some other reasons.
