• In single VGA card mode, use the PCIe 2.0 x16_1 slot (navy blue) for a PCI Express x16 graphics card to get better performance.

•In CrossFireX™ mode, use the PCIe 2.0 x16_1 and PCIe 2.0 x16_2 slots for PCI Express x16 graphics cards to get better performance.

•We recommend that you provide sufficient power when running CrossFireX™ mode.

Refer to page 2-26 for details.

•Connect a chassis fan to the motherboard connector labeled CHA_FAN1/2/3/4 when using multiple graphics cards for better thermal environment. See page 2-24 for details.
