Please realize that there is a certain risk involved with overclocking,
including adjusting the setting in the BIOS, applying Untied Overclocking
Technology, or using third-party overclocking tools. Overclocking may
affect your system’s stability, or even cause damage to the components
and devices of your system. It should be done at your own risk and
expense. We are not responsible for possible damage caused by
overclocking.

2. Installation
This is a 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.
Before you install or remove any component, ensure that the
power is switched off or the power cord is detached from the
power supply. Failure to do so may cause severe damage to the
motherboard, peripherals, and/or components.
1. Unplug the power cord from the wall socket before touching any
component.
2. To avoid damaging the motherboard components due to static elec-
tricity, NEVER place your motherboard directly on the carpet or the
like. Also remember to use a grounded wrist strap or touch a safety
grounded object before you handle components.
3. Hold components by the edges and do not touch the ICs.
4. Whenever you uninstall any component, place it on a grounded anti-
static pad or in the bag that comes with the component.
5. When placing screws into the screw holes to secure the mother-
board to the chassis, please do not over-tighten the screws! Doing
so may damage the motherboard.

2.1 CPU Installation
Step 1. Unlock the socket by lifting the lever up
to a 90
Step 2. Position the CPU directly above the
socket such that the CPU corner with
the golden triangle matches the socket
corner with a small triangle.
Step 3. Carefully insert the CPU into the
socket until it ts in place.
o
angle.
The CPU ts only in one correct
orientation. DO NOT force the CPU
into the socket to avoid bending of
the pins.
English

Step 4. When the CPU is in place, press it
rmly on the socket while you push
down the socket lever to secure the
CPU. The lever clicks on the side tab
to indicate that it is locked.
2.2 Installation of CPU Fan and Heatsink
After you install the CPU into this motherboard, it is necessary to install a
larger heatsink and cooling fan to dissipate heat. You also need to spray
thermal grease between the CPU and the heatsink to improve heat dis-
sipation. Make sure that the CPU and the heatsink are securely fastened
and in good contact with each other. Then connect the CPU fan to the
CPU FAN connector (CPU_FAN1, see Page 6, No. 2). For proper instal-
lation, please kindly refer to the instruction manuals of the CPU fan and
the heatsink.

2.3 Installation of Memory Modules (DIMM)
This motherboard provides two 240-pin DDR3 (Double Data Rate 3) DIMM
slots, and supports Dual Channel Memory Technology.
1. For dual channel conguration, you always need to install identical (the same
brand, speed, size and chip-type) DDR3 DIMM pairs.
2. It is unable to activate Dual Ch annel Memory Technology with only one memory
module install ed.
3. It is not allowed to install a DDR or DDR 2 memory module into a DDR3 slot;
otherwise, this mothe rboard and DIMM may be damaged.
e DIMM only ts in one correct orientation. It wil l cause permanent damage to
the mothe rboard and the DIMM if you force th e DIMM into the slot at incorrect
orientation.

2.4 Expansion Slots (PCI and PCI Express Slots)
There are 1 PCI slot and 2 PCI Express slots on this motherboard.
Before installing an expansion card, please make sure that the power supply
is switched off or the power cord is unplugged. Please r ead the documentation of the expansion card and make necessary hardware s ettings for the

2.5 Jumpers Setup
The illustration sh ow s how jumpers a re
setup. When the jumper cap is placed on
pins, the jumper is “Short”. If no jumper cap
is placed on pins, the jumper is “Open”. The
illus tration shows a 3-pi n jump er whos e
pin1 and pin2 are “Short” when jumper cap
is placed on these 2 pins.
Jumper Setting Description
Clear CMOS Jumper
(CLRCMOS1)
(see p.6, No. 16)
Note: CLRCMOS1 allows you to clear the data in CMOS. To clear and reset the
system parameters to default setup, please turn off the computer and unplug
the power cord from the power supply. After 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 after 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 ac-
tion. Please be noted that the password, date, time, user default prole, 1394
GUID and MAC address will be cleared only if the CMOS battery is removed.
Clear CMOSDefault
If you clear the CMOS, the case open may be detected. Please adjust the
BIOS option “Clear Status” to clear the record of previous chassis intrusion
status.
