Chapter 1: Product introduction

• 

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™.

• 

Connect a chassis fan to the motherboard connector labeled CHA_FAN1-3 when 

using multiple graphics cards for better thermal environment. 

• 

The PCIe x16_2 slot shares bandwidth with PCIe x1_1 and PCIe x2 slots. The default 

setting is x2 mode. Go to the BIOS Setup to change the settings.
