VGA configuration Single VGA/PCIe card Dual VGA/PCIe card PCI Express operating mode PCIe x16_1 x16 (Recommended for single VGA card) x16 PCIe x16_2 N/A x4 • In single VGA card mode, use the PCIe 2.0 x16_1 slot (blue) for a PCI Express x16 graphics card to get better performance. • PCIe x1 slot shares the bandwidth with PCIe x16_2 slot. Due to CrossFireX™ limitation, DO NOT use the PCIe x1 slot when you install two CrossFireX™ graphics cards on both the PCIe x16 slots to set up a CrossFireX™ cofiguration. To disable the PCIe x1 slot, refer to the Onboard Devices Configuration section in the BIOS for details. • We recommend that you provide sufficient power when running CrossFireX™ mode. See page 1-29 for details. • Connect a chassis fan to the motherboard connector labeled CHA_FAN1 or CHA_FAN2 when using multiple graphics cards for better thermal environment. ASUS P8H67 1-21
