I have an Asrock 970m Pro3 motherboard that is crossfirex compatable and 2 XFX RX 550 graphics cards, I have no crossfire option and gpux shows that crossfire is disabled. I've tried uninstalling them, removing the second card, and reinstalling the driver and shutting down to reinstall the second card, nothing. I've tried to reset my bios and flash the bios after uninstalling the drivers and reinstalling the drivers, still nothing. I don't know if there is a benefit to having two cards in a computer and not having crossfire, but I hope so. Otherwise I would have wasted my money, and with all the people having the same issue, AMD has to know what's going on. Has anyone been able to get crossfire to work out of the box, I don't see a lot of people posting success stories here.
