Do you have two HD 6900? Full model name of your motherboard?
1.Show me GPU-Z main screen for all your GPUs(you can select GPU on the bottom side of GPU-Z main screen)
2.Leave only one GPU in your PC!!!
3.Delete C:\AMD folder
4.Uninstall all AMD software and clean your system in safe mode by DDU programand install 15.7.1 sriver
5. Shut down PC and install your second GPU
Hello, Sorry for the delay

the global setting :AMD crossfire logo (on/off) why?
1. 15.7.1 is the last WHQL (and recommended) driver for your card. I suppose you have HD 6990?
Just stay on this driver (or use 15.8 if you want) if you have no problems with crossfire using these drivers.
2.All drivers newer than 16.2.1 are not supported your video card.
