Who is the manufacturer of both your AMD cards? So far as I understand 
things, its up to the manufacturer of the card to provide the appropriate ROM 
to suit the configuration of the card. Its likely that a ROM/BIOS update may 
fix your RX 480 card. Do both cards work under a pure Windows environment?
