In single VGA card mode, use first the PCIe 2.0 x16_1 slot (blue) or PCIe 2.0 x16_2 slot (blue) for a PCI Express x16 graphics card to get better performance.

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

See page 2-33 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 2-32 for details.
