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 thesystem.
If ATI Catalyst™ A.I. is enabled in the ATI Catalyst Control Center software, theoptimal rendering mode available for the application is automatically selected.

Installing ATI CrossFireX Graphics Cards
These instructions assume that a PCIe® graphics card has already beensuccessfully 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 hasan adequate power supply. A 550 watt or greater power supply isrecommended.

Troubleshooting ATI CrossFireX
The following are suggested solutions for common ATI CrossFireX
troubleshooting issues.

Change Motherboard BIOS Settings
Some motherboards may have a system BIOS option to switch between single
and dual PCIe slot support. The default setting may be single slot support. Referto the motherboard’s manual for information to enable dual PCIe slot support.
For more information see the ATI CrossFireX Web page at ati.amd.com/
crossfire.

Use Graphics Cards with Different Amounts of Memory
In some ATI CrossFireX configurations, graphics cards with different amounts ofmemory can by used; however, restarting your computer is required after
enabling ATI CrossFireX. This will cause ATI CrossFireX to reduce the amount ofmemory on the card with the most amount of memory to match the memory sizeof the graphics card with the least amount of memory.
Clicking OK to the memory mismatch error message will restart your computer.

Note: When disabling ATI CrossFireX you will be given the option torestart your computer to restore the original graphics memory size orcontinue with the reduced memory size.

Card Reversal Recommended
A recommendation message to reverse the graphics card positions may appear
if the primary graphics card is not installed into the primary PCIe slot. Although
ATI CrossFireX can be enabled, performance may be improved by reversing thegraphics cards in the computer.
See your motherboard’s manual to determine which is the primary PCIe slot.

3D Client is Active
You will not be able to start ATI CrossFireX if a 3D application, game, or video
playback, such as a DVD movie, is running.
Close all open 3D applications, games, and movie player applications, and thenenable ATI CrossFireX.

ATI CrossFireX is Currently Unavailable
This error has occurred because ATI CrossFireX did not correctly detect yourgraphics hardware or there is a problem with the software.
• Check that the graphics cards are installed correctly.
• Check that the interconnect cable is installed correctly.
• Close all running 3D applications.
• Re-install the ATI Catalyst Control Center and drivers.

Screen Rotation is Unavailable or Does Not Work
Screen rotation is not an available feature on ATI CrossFireX systems.

Video Displays Flicker During System Startup
This is normal during ATI CrossFireX start-up.

ATI CrossFireX Starts in Software Mode
This is normal when starting up for the first time after installing two
ATI CrossFireX graphics cards if neither card is installed in the primary
PCI Express® slot. You can change the ATI CrossFireX mode in the
ATI Catalyst Control Center.

ATI CrossFireX Disabled After Swapping/Moving Cards
If you change the ATI CrossFireX configuration by moving the graphics cards todifferent slots on the motherboard, disable ATI CrossFireX and restore factory
default settings in ATI Catalyst Control Center first. Once the cards have beenswapped, enable ATI CrossFireX. This ensures the new configuration is detectedby the computer.
