The problem that I comment here is a question of the AMD drivers that have been badly translated for many years. It shouldn't be a problem, but with the new Adrenaline drivers, it is sometimes hard to tell which option you have selected in Crossfire Mode.
The thing is that the translation of both "AFR friendly" and "AFR compatible" mode in Spanish is the same "Compatible con AFR". Actually "Friendly" would be more a "Amistoso" in Spanish.
I hope you can solve this problem in the next driver distributions.
