• 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_FAN1/2 when
using multiple graphics cards for better thermal environment. See pagg 2-23 for
details.
