Make certain that the graphics card is properly connected to the power supply and

6.1.2 Troubleshooting AMD CrossFire™

The following are suggested solutions for common AMD CrossFire™ troubleshooting

issues.

6.1.2.1 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. Refer to the

motherboard’s manual for information to enable dual PCIe slot support.

For more information, see the AMD CrossFire Web page at http://game.amd.com/us-

en/crossfirex_about.aspx.

6.1.2.2 Use Graphics Cards with Different Amounts of Memory

In some AMD CrossFire configurations, graphics cards with different amounts of

memory can by used; however, restarting your computer is required after enabling

AMD CrossFire. This will cause AMD CrossFire to reduce the amount of memory on

the card with the most amount of memory to match the memory size of the graphics

card with the least amount of memory.

Clicking OK to the memory mismatch error message will restart your computer.

Note: When disabling AMD CrossFire you will be given the option to restart your

computer to restore the original graphics memory size or continue with the reduced

memory size.
