HI all, Sorry, this is a question from a newbie, but one of my cards, a Sapphire Raedon RX580, was working fine, mining fine, then tried the new beta driver from AMD. When I rebooted, my pool, ethermine.org doesn't see it. It's fine in Windows, recognized in the Device Manager, and all looks good there, just not by the pool. Tried rolling back to the last driver, but that didn't help either. Any thoughts as to why Ethermine.org doesn't see it when I mine with it? Thanks.
