2.6 Expansion Slots (PCI and PCI Express Slots)
There are 2 PCI slots and 2 PCI Express slots on this motherboard.
PCI slots: PCI slots are used to install expansion cards that have the 32-bit PCI
interface.
PCIE slots:PCIE1 (PCIE 3.0 x16 slot) is used for PCI Express x16 lane width
graphics cards, or to install PCI Express graphics cards to support
CrossFireXTM function.
PCIE2 (PCIE 2.0 x16 slot) is used for PCI Express x4 lane width graph-
ics cards, or to install PCI Express graphics cards to support CrossFi-
reXTM function.
1. In single VGA card mode, it is recommended to install a PCI Express
x16 graphics card on PCIE1 slot.
2. In CrossFireXTM mode, please install the PCI Express x16 graphics
cards on PCIE1 and PCIE2 slots. Therefore, PCIE1 will work at x16
bandwidth, while PCIE2 works at x4 bandwidth.
3. Please connect a chassis fan to the motherboard’s chassis fan
connector (CHA_FAN1 or CHA_FAN2) when using multiple
graphics cards for better thermal environment.
4. Only PCIE1 slot supports Gen 3 speed. To run the PCI Express in
Gen 3 speed, please install an Ivy Bridge CPU. If you install a Sandy
Bridge CPU, the PCI Express will run only at PCI Express Gen 2
speed.
