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

•

components. Failure to do so may cause physical injuries 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.

2.1 Installing the CPU

1. Before you inser t the 1151-Pin CPU into the socket, please check if the PnP ca p
is on the socket, if the CPU sur face is unclean, or if th ere are any b ent pins in the
socket. Do not force to insert the CPU into the socket if above situ ation is found.
Other wise, the CPU wil l be seriously d amaged.

2. Unplug all power cables before installing the CPU.

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 install identical (the same

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

2. It i s unable to activate Dual Channel Memory Technology with only one or three
memor y module installed.

3. It i s not allowed to in stall a DDR , DDR2 or DDR3 memor y module into a DDR4
slot; otherwise, this motherboard and DIMM may be damaged.

e DIMM only ts in one correct orientation. It will cause permanent dam age to
the mothe rboard and the DIMM if you force the DIMM into the slot at incor rect
orientation .

2.4 Expansion Slots (PCI Express Slots)

ere are 4 PCI Express slots 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 slots:

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.8, No. 17)

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.8, No. 18)

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 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 ac tivity LED on the chassis front panel. e LED is on
when the hard drive i s reading or writing 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
assig nments and the pin assig nments are matched correctly.
