Chapter 2 Installation
is is an Micro ATX form factor motherboard. Before you install the motherboard,
study the conguration 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 overtighten the screws! Doing so may damage the motherboard.

2.1 Installing the CPU
1. Before you insert the 1150-Pin CPU into the socket, ple ase check if the PnP cap is on the
socket, if the CPU surface is unclean, or if there are any bent pins in the socket. Do not
force to in sert the CPU into the socket if above situation is found . Otherwise, the CPU
will be seriously damaged.
2. Unplug all power cables 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 conguration , you always need to in stall identical (the same brand,
speed , size and chip-type) DDR3 DIMM pairs.
2. It is unable to activate Dual Channel Memor y Technolog y with only one or three memory
module installed.
3. It is not allowed to install a DDR or DDR2 memory module into a DDR3 slot; other wise,
this motherboard and DIMM may be damaged.
e DIMM only ts in one correct orientation. It will cause permanent damage to the
motherboard and the DIMM if you force the DIMM into the slot at incorrect orientation.

e illustration shows how jumpers are setup. When the jumper cap is placed on
the pins, the jumper is “Short”. If no jumper cap is placed on the pins, the jumper
is “Open”. e illustration shows a 3-pin jumper whose pin1 and pin2 are “Short”
when a jumper cap is placed on these 2 pins.
Clear CMOS Jumper
(CLRCMO S1)
(see p.1, No. 12)
CLRCMOS1 allows you to clear the data in CMOS. To clear and reset the system
parameters to default setup, please turn o the computer and unplug the power
cord from the power supply. Aer waiting for 15 seconds, use a jumper cap to
short pin2 and pin3 on CLRCMOS1 for 5 seconds. However, please do not clear
the CMOS right aer you update the BIOS. If you need to clear the CMOS when
you just nish updating the BIOS, you must boot up the system rst, and then shut
it down before you do the clear-CMOS action. Please be noted that the password,
date, time, and user default prole will be cleared only if the CMOS battery is
removed.
Clear CMOSDefault
1. e Clear CMOS Switch has the same f unction as the Clear CMOS jumper.
2. If you clear the CMOS, the ca se open may be detected . Please adju st the BIOS option “Cl ear
Status” to clear the record of previous chassis intrusion status.
