Looks like the issue is with the CPU being one with Ryzen and Vega graphics the 2nd card needs to be in the 3rd pci-e slot which isn't reinforced. Looks like i'll need to get a regular ryzen now and the 3rd pci-e slot doesn't give me room to put another card nor are the slots in the back of my case to allow it.
Curious - is it only showing one of the 2 RX580's in Device Manager? If both are showing, are you talking about Radeon Settings only showing one GPU because Crossfire is enabled?
Yea like goodplay mentioned it has to do with the Ryzen chip I have. I have the 2400G which has the onboard video and for crossfire to work on that chip it needs to be on the pci16_3 slot but that's all the way on the bottom of the board and no room to fit a card on there in my mid-tower case. Ordered the Ryzen 1300 so I can use crossfire in the slots that are used now which is the pcie16_1 and pcie16_2 as those are the only 2 that will allow me to fit my cards. So bad CPU choice on my part as I didn't know that the Ryzen APUs needed to have cards in different positions on this particular board.
Sorry, I think you're misunderstanding what I asked. I was just curious about if 2 x RX580's are showing up in Windows Device Manager. Looking back how I phrased the question though - Crossfire would not be enabled in this scenario and that may have caused the confusion.
Either way, is there a specific reason you're looking into using Crossfire or which apps/games you plan playing with?
So like I mentioned and what goodplay posted it is because of the cpu used and slots used that caused the issue. So only 1 card shows up in device manager. The reason for crossfire? Just because I want to have it for games that could take advantage of it.
