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
This is a Mi ni-I TX form factor (6.7'' x 6.7 '', 17.0 cm x 17.0 cm) mot herb oa rd . Before
you install the motherboard, study the conguration 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.
English
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 cong uration , you always need to in stall identical (the same b rand,
speed , size and chip-type) DDR4 DIMM pairs.
2. 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.
3. Please install the memory module on CH0_A1 for the rst prior ity.
4. To activate Dual Channel Memory Technology, please follow the “Dual Channe l Memory
Conguration” table below.

2.4 Expansion Slots (PCI Express Slots)
ere is 1 PCI Express slots on this motherboard.
PCIE slot:
PCIE7 (PCIE 3.0 x16 slot) is used for PCI Express x16 lane width cards.
Installing an expansion card
Step 1. Before installing an expansion card, please make sure that the power
supply is switched o or the power cord is unplugged. Please read the
documentation of the expansion card and make necessary hardware
settings for the card before you start the installation.
Step 2. Remove the system unit cover (if your motherboard is already installed
in a chassis).

2.8 Dual LAN and Teaming Operation Guide
Dual LAN with Teaming enabled on this motherboard allows two single
connections to act as one single connection for twice the transmission bandwidth,
making data transmission more eective and improving the quality of transmission
of distant images. Fault tolerance on the dual LAN network prevents network
downtime by transferring the work load from a failed port to a working port.
e speed of transmission is subject to the actual network environment or status even with
Teaming enabled.
Before setting up Teaming, please make sure whether your Switch (or Router)
supports Teaming (IEEE 802.3ad Link Aggregation). You can specify a preferred
adapter in Intel PROSet. Under normal conditions, the Primar y adapter handles all
non-TCP/IP trac. e Secondary adapter will receive fallback trac if the primary
fails. If the Preferred Primary adapter fails, but is later restored to an active status,
control is automatically switched back to the Preferred Primary adapter.
Step 1
From Device Manager, open the properties of a team.
Step 2
Click the Settings tab.
Step 3
Click the Modif y Team button.
Step 4
Select the adapter you want to be the primary adapter and click the Set Primary
button.
If you do not specify a preferred primary adapter, the soware will choose an
adapter of the highest capability (model and speed) to act as the default primary. If
a failover occurs, another adapter becomes the primary. e adapter will, however,
rejoin the team as a non-primary.

SETUP UTILITY when you start up the computer. Please press <F2> or <Del> during the
Power-On-Self-Test (POST) to enter the UEFI SETUP UTILITY; otherw ise, POST will
continue with its test routines.
If you wish to enter the UEFI SETUP UTILITY a er POST, restart the system by pressing
<Ctrl> + <Alt> + <Delete>, or by pressing the reset button on the system chassis. You may
also restart by turning the system o and then back on.
Becau se the UEFI so ware is constantly being updated, the following UEFI setup sc reens
