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 (blue) for a PCI Express x16 graphics card to get better performance.

In CrossFireX™ mode, use the PCIe 3.0/2.0 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™ mode.

Connect a chassis fan to the motherboard connector labeled CHA_FAN when using multiple graphics cards for better thermal environment. See page 2-24 for details.
