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.

English

2.1 Installing the CPU

Unplug all power cables before installing the CPU.

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 be fore 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 instal l a DDR, DDR2 or DDR 3 memory modul e into a DDR4 slot; otherwise, thi s motherboard and DIMM may be damaged.

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

“O pen”.

English

Clear CMOS Jumper

(CLR CMOS1)

(see p.7, 8, No. 17)

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 adjus t the BIOS option “Clear Status” to cl ear the record of prev ious chassis intru sion status.
