Note: These features are only available for ATI Radeon HD 5750/5770 graphics
cards with ATI CrossFireX connections.
ATI CrossFireX Introduction
ATI CrossFireX is a multi-GPU (graphics processing unit) performance gaming
platform. It enables multiple graphics processors installed in a single computer
to work together to improve system performance, creating a high-performance
gaming platform. ATI CrossFireX setup involves two graphics cards and 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 an up-to-date listing of ATI CrossFireX certified motherboards and power
supplies, see ati.amd.com/products/certification.
