This is normal during AMD CrossFireX startup.
4.3.2.8 AMD CrossFireX™ Disabled After Swapping/Moving Cards
If you change the AMD CrossFireX configuration by moving the graphics cards to
different slots on the motherboard, disable AMD CrossFireX and restore factory
default settings in the Control Center software application first. Once the cards have
been swapped, enable AMD CrossFireX. This ensures the new configuration is
detected by the computer.
