ATI CrossFireX Introduction

ATI CrossFireX technology harnesses two or more GPUs (graphics processing
units) to be used in a single computer to run up to 2 displays, creating a high-
performance gaming platform. Typically, setup involves 2 or more graphics
cards, but with the appropriate motherboard, the technology can use a single
card and the built-in GPU of the motherboard. ATI CrossFireX works with all 3D
games and applications.
Note: The ATI Catalyst Control Center software contains a different
ATI CrossFireX user interface for each configuration type and automatically
loads the appropriate one when a valid ATI CrossFireX configuration is detected
in the system.
If ATI Catalyst™ A.I. is enabled in the ATI Catalyst Control Center software, the
optimal rendering mode available for the application is automatically selected.

Installing ATI CrossFireX Graphics Cards

These instructions assume that a PCIe® graphics card has already been
successfully installed in the secondary slot (slot one), and that the primary slot

Note: Consult your system builder or OEM to ensure that your system has an
adequate power supply. For more information, see
