Question My second AMD RX 480 is not detected by my computer. How do I make it detect it so I can use Crossfire?

Hello all,

I just installed a second RX 480 8 GB today (no need for a crossfire bridge) and it is not detected by my PC. I already tried reinstalling the AMD software and that didnt work. The second GPU does work though because I tried playing it by itself.

Any suggestions?

My motherboard is Z390 Godlike...

2 x AMD XFX RX 480 8GBs... and I only see one in Task Manager ?

the 480 is used I would assume. Does it have a mining bios?

It was never used for mining.

Sorry for the long delay. I was gaming, perhaps you've fixed the issue. Do your cards have dual bios? If so are they on the same bios setting?

Do each of the cards work on their own when each connected using the top slot?
