In single VGA card mode, use first the PCIe 2.0 x16_1 slot (blue) for a PCI Express

x16 graphics card to get better performance.

In CrossFireX™ or SLI™ mode, use the PCIe 2.0 x16_1 (blue) and PCIe 2.0 x16_2

(dark blue) slots for PCI Express x16 graphics cards to get better performance.

Use the three PCIe 2.0 x16 slots for Triple CrossFireX™ mode.

We recommend that you provide sufficient power when running CrossFireX™ or SLI™

mode. Refer to page 2-39 for details.

Connect a chassis fan to the motherboard connector labeled CHA_FAN1/2 when

using multiple graphics cards for better thermal environment. Refer to page 2-37 for
