Asus P8Z77-V PRO/THUNDERBOLT - Manual (Page 38)

2-14 Chapter 2: Hardware information
Chapter 2
• 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 (navy blue) for a PCI
Express x16 graphics card to get better performance.
• In CrossFireX™ or SLI™ mode, use the PCIe 3.0/2.0 x16_1 and PCIe 3.0/2.0 x16_2
slots for PCI Express x16 graphics cards to get better performance.
• We recommend that you provide sufficient power when running CrossFireX™ or SLI™
mode. Refer to page 2-31 for details.
• Connect a chassis fan to the motherboard connector labeled CHA_FAN1/2/3 when
using multiple graphics cards for better thermal environment. See page 2-30 for details.
