ATI CrossFireX Introduction
ATI CrossFireX technology harnesses two or more GPUs (graphics processing units) to be used in a single computer to run a display, 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
ATI CrossFireX is designed for optimal use on a single display; however, it is also possible for each GPU in an ATI CrossFireX configuration to individually drive their own monitors when ATI CrossFireX support is not enabled.
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 your 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
1.Make sure the computer, monitor, and other peripheral devices are off.
2.Unplug the computer power cord and disconnect the monitor cable from the back panel of the computer.
Caution:
To avoid possible damage to the motherboard, wait approximately 20 seconds after unplugging the power cord before disconnecting a peripheral or removing a component from the motherboard.
3.Remove the computer cover.
If necessary, consult the computer manual for help removing the cover.
