• PCIe 3.0 support depends on CPU type and requires PCIe 3.0 VGA card.

•In single VGA card mode, use the PCIe 3.0/2.0 x16_1 slot (navy blue) for a PCI

Express x16 graphics card to get better performance.

•In CrossFireX™ or SLI™ mode, use the PCIe 3.0/2.0 x16_1 and PCIe 3.0/2.0 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 2-31 for details.

•Connect a chassis fan to the motherboard connector labeled CHA_FAN1/2/3 when using multiple graphics cards for better thermal environment. See page 2-30 for details.
