Chapter 2 Installation

is is a Deep mini-ITX 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 four 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 in stall identical (the same
brand, speed , size and chip-type) DDR4 DIMM pairs.

2. It is unable to activate Du al Channel Memory Technology with only one or three
memory module installed.

3. It is not allowed to install a DDR, DDR2 or DDR3 memory module into a DDR4
slot; otherwise, this motherboard and DIMM may be damaged.

4. We suggest that you install the memory modules on DDR4_ A2 and DDR4_B2 rst
for better DRAM compatibility on 2 DIMM s conguration.

2.5 Jumpers Setup

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”.

English

Clear CMOS Jumper
(CLRCMO S1)
(see p.1, No. 13)

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 detec ted. Please adjust the BIOS option
“Clear Status” to clear the record of previou s chassis intrusion status.
