I am running a desktop with

GRAPHICS: 2x rx 480s with crimson 17.4.3 (17.4.4 now)

MOBO: msi b350 tomahawk motherboard

RAM: 16gigs of G.SKILL RIPJAWS V at 2400


OS: windows 10 64 bit

MONITOR: asus MG248Q monitor displayport

PSU: 750w thermaltake 80 plus bronze SMART series SP-750PCBUS


In my global settings there are no options to enable crossfire, why is this? I was under the impression that rx 480's and mobos with b350 chipset supported crossfire. pic related

I have uninstalled and reinstalled the drivers multiple times and I have never seen crossfire settings in global settings


EDIT: I have identified and resolved the problem; in my case, my motherboard drops down its pcie 2.0 x16 to x4 when going into crossfire which is normal, but drops it down to x2 when any other pcie port is used other than the pcie 3.0 16x and pcie 2.0 16x. I did not realize that it was relevant, but I had a wifi card installed that was preventing me from enabling crossfire.
