Hey guys, I just purchased a QNIX QX2710 LED Evolution ll SE monitor that uses dual-link dvi. I have two R9 290s and after plugging the monitor into the first one, it makes the 2nd one undetectable. The option is gone from CCC as well.

I have tried both 13.11 and the new 14.x beta drivers as well as the normal 13.2. No success so far.

Solved. I was using CRU by Toastyx. To keep Crossfire active you must have all GPUs running at the same refresh rate. Hopefully this will be helpful to someone.
