Chapter 2 ATI CrossFireX Technology 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 highperformance 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 (slot zero) is empty. Note: Consult your system builder or OEM to ensure that your system has an adequate power supply. A 550 watt or greater power supply is recommended. For an up-to-date listing of ATI CrossFireX certified motherboards, see ati.amd.com/products/certification 1. Make sure the computer, monitor, and other peripheral devices are off. 2.
