• In single VGA card mode, use first the PCIe 2.0 x16_1 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_3

(white) slots for PCI Express x16 graphics cards to get better performance.

• Use the two PCIe 2.0 x16 slots and the two PCIe x16 slots for Quad
