1.3 Unique Features

ASRock Instant Flash is a BIOS ash utility embedded in Flash ROM. is conve-

nient BIOS update tool allows you to update system BIOS without entering operating

systems rst like MS-DOS or Windows®. With this utility, you can press the <F6> key

during the POST or the <F2> key to enter into the BIOS setup menu to access ASRock

Rack Instant Flash. Just launch this tool and save the new BIOS le to your USB ash

drive, oppy disk or hard drive, then you can update your BIOS only in a few clicks

without preparing an additional oppy diskette or other complicated ash utility.

Please be noted that the USB ash drive or hard drive must use FAT32/16/12 le

system.

Chapter 2 Installation

is is a mATX form factor (9.6'' x 9.6'', 24.4 cm x 24.4 cm) motherboard. Before you install

the motherboard, study the conguration of your chassis to ensure that the motherboard

ts into it.

Make sure to unplug the power c ord before installing or re moving the mothe rboard. Failure
to do so may cause physical injurie s to you and d amages to motherboard components.

2.1 Screw Holes

Place screws into the holes indicated by circles to secure the motherboard to the chassis.

Do not over-tighten the screws! Doing so may damage the motherboard.

2.2 Pre-installation Precautions

Take note of the following precautions before you insta ll motherboard components or

change any motherboard settings.

1. Unplug the power cord from the wall socket before touching any components.

2. To avoid damaging the motherboard ’s components due to static electricity, NEVER

place your motherboard directly on the carpet or the like. Also remember to use a

grounded wrist strap or touch a safety grounded object before you handle the compo-

nents.

3. Hold components by the edges and do not touch the ICs.

4. Whenever you uninstall any component, place it on a grounded anti-static pad or in

the bag that comes with the component.

5. When placing screws into the screw holes to secure the motherboard to the chassis,

please do not over-tighten the screws! Doing so may damage the motherboard.

Before you install or remove any component, ensure that the power is switched o or the
power cord is detached f rom the power supply. Failure to d o so may cau se severe damage to
the motherboard, peripherals, and/or components.

2.3 Installation of 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 is not allowed to install a DDR, DDR 2 or DDR3 memory module into a DDR4 slot;
otherwise , this motherboard and DIM M may be damaged.

3. Please install the memor y module on CH0_ A1 for the rst priority.

4. To activate Dual Channel Memory Technology, please follow the “Dual Channel Memor y
Conguration” table below.

*Since instal ling thre e memor y modules is NOT supported on this motherboard, we suggest not u sing

this conguration.

e DIMM only ts in one correct orientation. It will cause permanent dam age to the
motherboard and the DIMM if you force the DIMM into the slot at incorrect orientation.
