CrossFire Starts in Software Mode
This is normal when starting up for the first time after installing two CrossFire
graphics cards if neither card is installed in the primary PCI Express® slot. You
can change the CrossFire mode in the ATI Catalyst Control Center.
CrossFire Disabled After Swapping/Moving Cards
If you change the CrossFire configuration by moving the graphics cards to
different slots on the motherboard, disable CrossFire in
ATI Catalyst Control Center first. Once the cards have been swapped, enable
CrossFire. This ensures the new configuration is detected by the computer.
