2.4 Expansion Slots (PCI and PCI Express Slots)

There are 2 PCI slots and 5 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 / 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

or SLI

function.

PCIE2 / PCIE5 (PCIE 2.0 x1 slots) are used for PCI Express cards with

x1 lane width cards, such as Gigabit LAN card, SATA2 card, etc.

PCIE4 (PCIE 3.0 x16 slot) is used for PCI Express x8 lane width graph-

ics cards, or used to install PCI Express graphics cards to support

3-Way CrossFireX

or 3-Way SLI

function.

1. In single VGA card mode, it is recommended to install a PCI Express

x16 graphics card on PCIE1 slot.

2. In CrossFireX

mode or SLI

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

or 3-Way SLI

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.

Installing an expansion card

Step 1. Before installing the expansion card, please make sure that the power

supply is switched off or the power cord is unplugged. Please read the

documentation of the expansion card and make necessary hardware

settings for the card before you start the installation.

Step 2. Remove the system unit cover (if your motherboard is already installed

in a chassis).

Step 3. Remove the bracket facing the slot that you intend to use. Keep the

screws for later use.
