In single VGA card mode, use first the PCIe 2.0 x16_1 slot (beige) for a PCI Express
x16 graphics card to get better performance.
•
In CrossFireX™ or SLI™ mode, use the PCIe 2.0 x16_1 (beige) and PCIe 2.0 x16_2
(beige) slots for PCI Express x16 graphics cards to get better performance.
•
When the PCI Express x1_2 slot is occupied, the PCI Express x16 slot (black) will
work at x1 link.
•
When using the triple VGA card mode, we recommend that you use the PCI Express
x1_1 slot to install a PCIe x1 device to get better performance.
•
We recommend that you provide sufficient power when running CrossFireX™ or SLI™
mode. See page 2-35 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 2-33 for
