Hello, i bought second handed Asus rx 470 4g mining. The problem is that after driver install it says : "No AMD driver installed or not functioning properly" . DDU didnt help. So I was thinking that I could try reinstall bios but unfortunately amdvbflash win does not see the gpu, its only recognizing the cpu. I checked hwinfo and current bios is 015.050.000.001.000000. What should i do ? thanks
