Chapter 2 Installation

is is a Micro ATX form factor motherboard. Before you install the motherboard,

study the conguration of your chassis to ensure that the motherboard ts into it.

Pre-installation Precautions

Take note of the following precautions before you install motherboard components

or change any motherboard settings.

Make sure to unplug the power cord before installing or removing the motherboard.

•

Failure to do so may cause physical injuries to you and damages to motherboard

components.

In order to avoid damage from static electricity to the motherboard’s components,

•

NEVER place your motherboard directly on a carpet. Also remember to use a grounded

wrist strap or touch a safety grounded object before you handle the components.

Hold components by the edges and do not touch the ICs.

•

Whenever you uninstall any components, place them on a grounded anti-static pad or

•

in the bag that comes with the components.

When placing screws to secure the motherboard to the chassis, please do not over-

•

tighten the screws! Doing so may damage the motherboard.

2.1 Installing the CPU

1. Before you insert the 1150-Pin CPU into the socket, please che ck if the PnP cap is on
the socket, if the CPU surfa ce is unclean, or if there are any bent pins in the socket.
Do not force to insert the CPU into the socket if above situation is found. Otherwise,
the CPU will be seriously damaged .

2. Unplug all power c ables before in stalling the CPU.

2.3 Installing Memory Modules (DIMM)

is motherboard provides four 240-pin DDR3 (Double Data Rate 3) DIMM slots,

and supports Dual Channel Memory Technology.

1. For dual channel conguration, you always need to install identica l (the same

brand, speed , size and chip-type) DDR3 DIMM pairs.

2. It is unable to activate Dual Channel Memor y Technology with only one or three
memor y module installed.

3. It is not allowed to install a DDR or DDR2 memory module into a DDR3 slot;
otherwise , this motherboard and DIM M may be damaged.

switched o or the power cord is unplugged. Plea se read the documentation of the
expan sion card and mak e necessary hardware settings for the card before you start
the installation.

PCI slot:

e PCI1 and PCI2 slots are used to install expansion cards that have 32-bit PCI

interface.

PCIe slots:

PCIE1 (PCIe 3.0 x16 slot) is used for PCI Express x16 lane width graphics cards.
