2.6  Expansion Slots (PCI and PCI Express Slots)

There are 2 PCI slots and 4 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

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.

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. 

Step 4. 

Align the card connector with the slot and press fi rmly until the card is  

completely seated on the slot. 

Step 5. 

Fasten the card to the chassis with screws. 

Step 6.  

Replace the system cover.
