Safety information
Electrical safety
To prevent electrical shock hazard, disconnect the power cable from the electrical outlet
before relocating the system.
When adding or removing devices to or from the system, ensure that the power cables
for the devices are unplugged before the signal cables are connected. If possible,
disconnect all power cables from the existing system before you add a device.
Before connecting or removing signal cables from the motherboard, ensure that all
power cables are unplugged.
Seek professional assistance before using an adapter or extension cord. These devices
could interrupt the grounding circuit.
Ensure that your power supply is set to the correct voltage in your area. If you are not
sure about the voltage of the electrical outlet you are using, contact your local power
company.
If the power supply is broken, do not try to x it by yourself. Contact a qualied service
technician or your retailer.
Operation safety
Before installing the motherboard and adding components, carefully read all the manuals
that came with the package.
Before using the product, ensure all cables are correctly connected and the power
cables are not damaged. If you detect any damage, contact your dealer immediately.

slots, sockets and circuitry.
Avoid dust, humidity, and temperature extremes. Do not place the product in any area
where it may be exposed to moisture.
Place the product on a stable surface.
If you encounter technical problems with the product, contact a qualied service
technician or your retailer.

Motherboard overview
Unplug the power cord from the wall socket before touching any component.
Before handling components, use a grounded wrist strap or touch a safely grounded
object or a metal object, such as the power supply case, to avoid damaging them due
to static electricity.
Before you install or remove any component, ensure that the ATX power supply is
switched off or the power cord is detached from the power supply. Failure to do so
may cause severe damage to the motherboard, peripherals, or components.
Unplug the power cord before installing or removing the motherboard. Failure to do so
can cause you physical injury and damage to motherboard components.

CPU and chassis fan connectors; AIO pump connector (4-pin CPU_FAN,
4-pin CHA_FAN1/2/3; 4-pin AIO_PUMP)
Connect the fan cables to the fan connectors on the motherboard, ensuring that the
black wire of each cable matches the ground pin of the connector.
Do not forget to connect the fan cables to the fan connectors. Insufcient air ow inside
the system may damage the motherboard components. These are not jumpers! Do not
place jumper caps on the fan connectors! The CPU_FAN connector supports a CPU fan
of maximum 1A (12 W) fan power.
AMD AM4 CPU socket
This motherboard comes with an AMD AM4 socket designed for AMD Ryzen™
2
nd

processors.
For more details, refer to Central Processing Unit (CPU).
Aura RGB Strip header (4-pin RGB_HEADER)
This header is for RGB LED strip.
ATX power connectors (24-pin EATXPWR, 8-pin EATX12V)
These connectors are for ATX power supply plugs. The power supply plugs are
designed to t these connectors in only one orientation. Find the proper orientation
and push down rmly until the connectors completely t.
For a fully congured system, we recommend that you use a power supply unit
(PSU) that complies with ATX12V Specication 2.0 (or later version) and provides a
minimum power of 350 W. This PSU type has 24-pin and 8-pin power plugs.
DO NOT forget to connect the 8-pin EATX +12V power plug. Otherwise, the system
will not boot up.
We recommend that you use a PSU with higher power output when conguring a
system with more power-consuming devices or when you intend to install additional
devices. The system may become unstable or may not boot up if the power is
inadequate.
If you are uncertain about the minimum power supply requirement for your system,
refer to the Recommended Power Supply Wattage Calculator at http://support.
asus.com/PowerSupplyCalculator/PSCalculator.aspx?SLanguage=en-us for
details.
The RGB header supports 5050 RGB
multi-color LED strips (12V/G/R/B), with a
maximum power rating of 3A (12V), and
no longer than 3m.

Before you install or remove any component, ensure that the ATX power supply is
switched off or the power cord is detached from the power supply. Failure to do so may
cause severe damage to the motherboard, peripherals, or components.
Actual lighting and color will vary with LED strip.
If your LED strip does not light up, check if the RGB LED extension cable and the
RGB LED strip is connected in the correct orientation, and the 12V connector is
aligned with the 12V header on the motherboard.
The LED strip will only light up when the system is operating.
The LED strips are purchased separately.
DDR4 DIMM slots
Install 2 GB, 4 GB, 8 GB, and 16 GB unbuffered DDR4 DIMMs into these DIMM sockets.

storage devices.
The M.2 Socket shares bandwidth with the SATA_5/6
ports, and therefore the SATA_5/6 ports cannot be used
when an M.2 device is installed.
AMD Serial ATA 6.0Gb/s connectors (7-pin SATA6G_1~6)
These connectors connect to Serial ATA 6.0 Gb/s hard disk drives via Serial ATA
6.0 Gb/s signal cables.
System panel connector (20-5 pin F_PANEL)
This connector supports several chassis-mounted functions.
USB 3.1 Gen 1 (up to 5Gbps) connector (20-1 pin U31G1_12)
Connect a USB 3.1 Gen 1 module to this connector for additional USB 3.1
Gen 1 front or rear panel ports. This connector complies with USB 3.1 Gen 1
specications and provides faster data transfer speeds of up to 5 Gbps, faster
charging time for USB-chargeable devices, optimized power efciency, and
backward compatibility with USB 2.0.
USB 2.0 connectors (10-1 pin USB34,USB56)
Connect a USB module cable to any of these connectors, then install the module
to a slot opening at the back of the system chassis. These USB connectors comply
with USB 2.0 specications and support up to 480Mbps connection speed.

Clear RTC RAM (2-pin CLRTC)
This header allows you to clear the CMOS RTC RAM data of
the system setup information such as date, time, and system
passwords.
To erase the RTC RAM:
1. Turn OFF the computer and unplug the power cord.
2. Use a metal object such as a screwdriver to short the
two pins.
3. Plug the power cord and turn ON the computer.
4. Hold down the <Del> key during the boot process and
enter BIOS setup to re-enter data.

Chapter 1: Product introduction
System memory
Overview
This motherboard comes with four Double Data Rate 4 (DDR4) Dual Inline Memory Module
(DIMM) sockets. The gure illustrates the location of the DDR4 DIMM sockets:
You may install varying memory sizes in Channel A and Channel B. The system
maps the total size of the lower-sized channel for the dual-channel conguration. Any
excess memory from the higher-sized channel is then mapped for single-channel
operation.
Always install DIMMs with the same CAS latency. For optimal compatibility, we
recommend that you install memory modules of the same version or date code (D/C)
from the same vendor. Check with the retailer to get the correct memory modules.
Recommended memory conguration
Channel Sockets
Channel A DIMM_A1 & DIMM_A2*
Channel B DIMM_B1 & DIMM_B2*
For system stability, use a more efcient memory cooling system to support a full
memory load (4 DIMMs).
