No Enable Crossfire option in Crimson (16.6.2) for dual Sapphire RX 480s

As mentioned in title, I've just today purchased a second brand new RX 480 since I've heard real good things about the crossfire capabilities and my first one was doing pretty well (aside from the somewhat unstable Global Wattman section in Crimson which I just chose to avoid until the next driver update).

 

This is a fresh installation of Windows 10, fully up to date. I've tried uninstalling then installing earlier versions of the crimson drivers. I'm just not getting that elusive crossfire option in Crimson on either global or and game profiles! Pretty frustrated to be honest and haven't found anything on the forums to help as of yet.

 

As you can see below, both cards are being picked up, I can ramp up the fan speeds of both of them and that seems to work fine, but I'm getting no performance increase in any games (nor firestrike) and can see no options in crimson to enable crossfire anywhere.. Help?
