such as a DVD movie, is running.
Close all open 3D applications, games, and movie player applications, and then enable
AMD CrossFire.

This error has occurred because AMD CrossFire did not correctly detect your
graphics hardware or there is a problem with the software.

Check that the interconnect cable, if applicable, is installed correctly.
•
Close all running 3D applications.

application. (The AMD Radeon™ HD 7750/7770 can only use AMD CrossFire
