•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™ or SLI™ mode, use the PCIe 2.0 x16_1 (blue) and PCIe 2.0 x16_2 (white) slots for PCI Express x16 graphics cards to get better performance.

•Use the three PCIe 2.0 x16 slots for 3-Way CrossFireX™ mode.

•If you install a PCIe x16 graphics card on to the PCIe x16_1 slot, a PCIe device with a bandwidth faster than x8 link to the PCIe x16_2 slot, and a PCIe device with a bandwidth slower than x4 link to the PCIe x16_3 slot, the three PCIe x16 slots will work at x16, x16, x1 link as the default.

•If you install a PCIe x16 graphics card on to the PCIe x16_1 slot, a PCIe device with a bandwidth slower than x8 link to the PCIe x16_2 slot, and a PCIe device with a bandwidth faster than x4 link to the PCIe x16_3 slot, the three PCIe x16 slots will work at x16, x8, x8 link as the default.

•You may manually reassign the link width of PCIe x16_2 and PCIe x16_3 slots in BIOS settings. See page 3-28 for details.

•We recommend that you provide sufficient power when running

CrossFireX™ or SLI™ mode. See page 2-36 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 2-34 for details.
