Note: These features are available only for ATI Radeon™ 4000 Series graphics

cards with ATI CrossFireX connections.

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.

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.
