Chapter 2 Installation

is is an 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.

2.3 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g uration , you always need to in stall identical (the same b rand,

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

2. It is unable to activate Dual Channel Memor y 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 sl ot;
otherwise , this motherboard and DIM M 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”.

Clear CMOS Jumper

(CLRCMO S1)

(see p.8, No. 25)

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.
