I bought 2 radeon r7 360 2gb gddr5 video cards. I want to put them in a crossfire. but I notice there is no place to put the crossfire connector. It says it has an internal bus connection but something is wrong with it and it wont work. It says they are crossfire ready but then deny's me from putting it in crossfire mode can anyone tell me how to fix this problem? I could really use some help on this one thank you.
