Chapter 2 Installation

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

1. For dual channe l conguration, you always need to in stall identical (the same

brand, speed , size and chip-type) DDR4 DIMM pairs.

2. It is una ble to activate Dual Channel Memo ry Technology with only one me mory
module instal led.

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.

ere is 1 PCI Express slot on the motherboard.

Before installing an ex pansion card, please make sure that the power supply is
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.

PCIe slot:

PCIE1 (PCIe 3.0 x16 slot) is used for PCI Express x16 lane width graphics cards.*
* PCIE1 will downgrade to x8 mode when A-Series APU / Raven Ridge CPU is
installed.

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”. 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
(CLRMOS1)
(see p.6, No. 16)

CLRMOS1 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. Aer waiting for 15 seconds, use a jumper cap to
short pin2 and pin3 on CLRMOS1 for 5 seconds. However, please do not clear the
CMOS right aer 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 prole will be cleared only if the CMOS battery is
removed.

2.6 Onboard Headers and Connectors

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

System Panel Header
(9-pin PANEL1)
(see p.6, No. 14)

PWRBTN (Power Switch):

Connec t to the power switch on the chassi s front panel. You may congure the way to
turn o your system using the power switch.

RESET (Reset Switch):

Connec t to the reset switch on the chassi s front panel. P ress the reset sw itch to restart
the computer if the compute r freezes and fails to perform a normal restart.

PLED (Syste m Power LED):

Connec t to the power status indicator on the chassis front panel. e LED i s on when
the system is ope rating. e LED keeps blinking when the system i s in S3 sleep state.
e LED is o when the system i s in S4 sle ep state or powered o (S5).

HDLED (Ha rd Drive Activity LED):

Connec t to the hard drive ac tivity LED on the chassis front panel. e LED is on when
the hard dr ive is reading or w riting data.

e front panel de sign may dier by chassis. A front pane l module mainly consists
of power switch , reset switch, power LED, hard dr ive activity LED, speak er and etc.
When connecting your chassis front panel module to this head er, make sure the wire
