1.3 Unique Features
ASRock Rack Instant Flash is a BIOS ash utility embedded in Flash ROM. is con-
venient BIOS update tool allows you to update system BIOS without entering operat-
ing 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 i s a Mini IT X form f ac tor (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 Installing the CPU and Heatsink
1. Before you insert the CPU into the socket, please check if the PnP cap is on the socket ,
if the CPU sur face is unclean, or if there are any bent pins in the socket. Do not force to
inser t the CPU into the socket if above situation is found. Oth erwise, the CPU will be
seriously damaged.
2. Unplug all power c ables before in stalling the CPU.

(Double Data Rate 4) SO-DIMM slots, and supports Daul, Quad and Six Channel Memory
Tech nolo gy.
1. For dual, quad and six channe l conguration, you always need to install identical (the
same bran d, spe ed, size and chip-ty pe) DDR4 SO-DIM M pairs.
2. It is unable to activate Dual Channel Memor y Technology with only one or three memor y
module installed.
3. It is required to in stall all four memory modules to activate Quad Channel Memory
Technology.
4. It is not allowed to install a DDR, DDR2 or DDR3 memory module into a DDR4 sl ot;
otherwise , this motherboard and SO-DIMM may be damaged.

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).
Step 3. Remove the bracket facing the slot that you intend to use. Keep the
screws for later use.
Step 4. Align the card connector with the slot and press rmly until the card is
completely seated on the slot.
Step 5. Fasten the card to the chassis with screws.
Step 6. Replace the system cover.

To install the drivers to your system, please insert the support CD to your optical

on the support CD driver page. Please follow the order from top to bottom to install
those required drivers. erefore, the drivers you install can work properly.

2.9 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 (Adapter Fault Tolerance (AFT), Switch Fault Tolerance (SFT)
and Adaptive Load Balancing (ALB) teams). You can specify a preferred adapter in
Intel PROSet. Under normal conditions, the Primary 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.

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 u pdated, the following UEFI se tup screens
