4.1 AMD CrossFire™ Overview
AMD CrossFire technology is designed to enhance the graphics quality and
performance of 3D games and applications by combining the processing power of
multiple AMD Radeon graphics cards, essentially creating a multi-GPU performance
gaming platform. A typical AMD CrossFire setup involves two graphics cards.

4.2 Installing Additional Graphics Cards for
AMD CrossFire™
Before installing an additional graphics card, make sure that your system meets the
recommended system requirements for AMD CrossFire technology. If needed,
consult your system builder or OEM to confirm that your system has an adequate
power supply.
For optimal performance, it is recommended that each AMD Radeon™ R7 360 graphics
card be separated by at least one empty expansion slot. For more information, see the
installation instructions for your graphics card.

4.3 Enabling and Configuring AMD CrossFire™

Once all your graphics cards are properly installed, you can begin enabling and
configuring AMD CrossFire technology support using the AMD Radeon software
application, which is a component of the AMD graphics driver that can be downloaded
from the Drivers and Support page at http://support.amd.com.
When AMD CrossFire is enabled, the graphics processor in one of the cards acts as the
primary processor; this card is known as the primary graphics card. Graphics-
rendering tasks are shared between all available processors to accelerate displays that
are connected to the primary card. By default, displays that are connected to other
graphics cards are disabled but may be enabled by unlocking them.
Note that AMD CrossFire technology can be use with AMD Eyefinity technology
however displays must be connected to the primary graphics card.
