In single VGA card mode, use the PCIe 3.0/2.0 x16_1 slot (yellow) for a PCI Express x16 graphics card 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_FAN1-2 when using multiple graphics cards for better thermal environment.

The PCIe x16_2 slot shares bandwidth with PCIe x1_2 slot. The default setting is x2 mode. Go to the BIOS setup to change the settings.
