so i have 2 XFX rx580 8gb on my X99-E-10G WS and it will not let me put them in crossfire mode, I am running driver version Adrenalin Edition 18.5.1 on windows 10 64bit.
I have tried moving the cards around just for fun, but nothing changes, one is running x16 and the other 8x but that shouldn't be a problem?
