PCI slots: PCI slots are used to install expansion cards that have the 32-bit PCI
interface.
PCIE slots: PCIE1 / PCIE3 (PCIE 3.0 x16 slots) are used for PCI Express x16 lane
width graphics cards, or used to install PCI Express graphics cards to
support CrossFireX
TM or SLI TM function.
PCIE2 (PCIE 2.0 x1 slot) is used for a PCI Express x1 lane width card,
such as Gigabit LAN card or SATA2 card, etc.
PCIE4 (PCIE 3.0 x16 slot) is used to install a PCI Express graphics card
to support 3-Way CrossFireX
TM , 3-Way SLI TM function or to install an AS-
Rock Game Blaster card.
1. In single VGA card mode, it is recommended to install a PCI Express
x16 graphics card on PCIE1 slot.
2. In CrossFireX TM mode or SLI TM mode, please install PCI Express x16
graphics cards on PCIE1 and PCIE3 slots. Therefore, both these two
slots will work at x16 bandwidth.
3. In 3-Way CrossFireX TM or 3-Way SLI TM mode, please install PCI
Express x16 graphics cards on PCIE1, PCIE3 and PCIE4 slots.
Therefore, both PCIE1 and PCIE3 will work at x16 bandwidth, while
PCIE4 works at x8 bandwidth.
4. Please connect a chassis fan to motherboard chassis fan connector
(CHA_FAN1, CHA_FAN2 or CHA_FAN3) when using multiple
graphics cards for better thermal environment.
5. Currently Intel ® Socket 2011 Sandy Bridge-E Processor doesn’t
support PCIE 3.0, but this motherboard is already PCIE 3.0 hardware
ready. It depends on Intel’s CPU to enable PCIE 3.0. Please check
Intel’s website for information on future CPU updates and releases.
