Note: These features only available for ATI Radeon HD 4770 graphics cards with
ATI CrossFireX connections.

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 two displays, creating a high-
performance gaming platform. Typically, setup involves two 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
(slot zero) is empty.
Note: Consult your system builder or OEM to ensure that your system has an
adequate power supply. For more information, see
