In single VGA card mode, use the PCIe 2.0 x16_1 slot (beige) for a PCI Express x16

graphics card to get better performance.

In CrossFireX™ or SLI™ 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™ or SLI™

mode. Refer to page 2-22 for details.

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

multiple graphics cards for better thermal environment. See page 2-20 for details.
