Please realize that there is a certain risk involved with overclocking, including adjust­ing the setting in the BIOS, applying Untied Overclocking Technology, or using third­party overclocking tool s. Overclocking may aect 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 re sponsible for possible damage caused by overclocking.

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.

2.2 Installing the CPU Fan and Heatsink

Aer 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 dissipation. Make sure that the
CPU and the heatsink are securely fastened and in good contact with each other.

Please turn o the power or remove the power cord before changing a CPU or heatsink .

2.3 Installing Memory Modules (DIMM)

is motherboard provides two 288-pin DDR4 (Double Data Rate 4) DIMM slots,
and supports Dual Channel Memory Technology.

1. For dual channel conguration, you always need to install identical (the same
brand, speed, size and chip-ty pe) DDR4 DIMM pairs.

2. It is unable to activate Dual Channel Memory Technology w ith only one memor y
module installed.

3. It is not allowed to install a DDR, DDR2 or DDR 3 memory modul e into a DDR4
slot; otherwise, this motherboard and DIMM may be damaged.

Clear CMOS Header
(CLRCMOS1)
(see p.1, No. 16)

CLRCMOS1 allows you to clear the data in CMOS. e data in CMOS includes
system setup information such as system password, date, time, and system setup
parameters. To clear and reset the system parameters to default setup, please
turn o the computer and unplug the power cord, then use a jumper cap to short
the pins on CLRCMOS1 for 3 seconds. Please remember to remove the jumper
cap aer clearing the CMOS. 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.

If you clear the CMOS, the case open may be detected. Please adjust the BIOS option
“Clear Status” to clear the record of prev ious chassis intru sion status.

Onboard headers and connectors are NOT jumpers. Do NOT place jumper caps over
these headers and connectors. Placing jumper caps over the headers and connectors
will cause permanent damage to the motherboard.

System Panel Header
(9-p in PA NEL1)
(see p.1, No. 12)

PWRBTN (Power But ton):

Connec t to the power button on the chassis f ront panel. You may congure the way to turn
o your system using the power button.

RESET (Reset Button):
Connec t to the reset button on the chassis f ront panel. Pre ss the reset button to restart the
computer if the computer freezes and fails to perform a normal restart.

PLED (Syste m Power LED):
Connec t to the power status indicator on the chassi s front panel. e LED is on when the
system is operating. e LED keeps blinking when the system is in S1/S3 sleep state. e
LED is o when the system is in S4 sleep state or powered o (S5).

HDLED (Ha rd Drive Activity LED):
Connec t to the hard drive activity LED on the chassis f ront panel. e LED is on when the
hard drive is reading or writing data .

e front panel design may dier by chassis . A front panel module mainly consists of powe r
button, reset button, power LED, hard drive a ctivity LED, speaker and etc. When connect­ing your chassis front panel module to this header, make sure the wire assig nments and the
pin assignments are matched correctly.

2. If you use an AC’97 audio panel , please install it to the f ront panel audio header by
the steps below:
A. Connect Mic_ IN (MIC) to MIC2_L.
B. Conne ct Audio_R (RIN) to OUT2 _R and Audio_ L (LIN) to OUT2_ L.
C. Connect Ground (GND) to Ground (GND).
D. MIC_ RET and OUT_RET are for the HD audio panel only. You don’t need to con­nect them for the AC’97 audio panel.
E. To activate the front mic, go to the “FrontMic” Tab in the Realtek Control panel
and adjust “Recording Volume”.
