I'm building a new pc and I have 2 Radeon RX 460 4GB cards but only 1 card will display on the monitors connected to it, the 2nd card shows in the device manager but it wont display anything on the 2 monitors attached. I've removed each card and tried it with 1 at a time, switching from one pcie slot to the other and both cards work by themselves in either pcie slot but not when they are both installed. Anybody have any ideas? I have a Gigabyte 970 gaming sli board that newegg recommended these video cards to use with this board.
I figured it out, by default the software turns on crossfire and doesn't give you the option during install to not turn it on so you have to turn off crossfire in the global settings. Once you turn it off you can view all monitors attached to your pc instead of just 2.
