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.

To achieve the optimum performance for CrossFireX™ mode, set the PCI Express

X16_2 slot (black) bandwidth BIOS item to [x4 mode]. Refer to page 3-20 for details.

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

Refer to page 2-28 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 2-27 for details.
