Chapter 1: Product introduction

• 

In single VGA card mode, use the PCIe 3.0/2.0 x16_1 slot (gray) 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_FAN1/2/3 when 

using multiple graphics cards for better thermal environment. 

• 

The PCIe x1_1 and PCIe x1_2 slots share bandwidth with the PCIe x16_2 slot. 

The PCIe x16_2 slot runs at x2 mode as default. Please check BIOS for more 

configuration.
