ASUS P8H77-M 用户手册

Chapter 1: Product introduction

•  PCIe 3.0 support depends on CPU type and requires PCIe 3.0 VGA card.
•  In single VGA card mode, use the PCIe 3.0/2.0 x16_1 slot (blue) for a PCI Express x16 

graphics card to get better performance.

•  In CrossFireX™ mode, use the PCIe 3.0/2.0 x16_1 and PCIe 2.0 x16_2 slots for PCI 

Express x16 graphics cards 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_FAN when using 

multiple graphics cards for better thermal environment. See page 2-24 for details.
