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

1.1 Before you proceed
Take note of the following precautions before you install motherboard components or
change any motherboard settings.
• 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.
• Hold components by the edges to avoid touching the ICs on them.
• Whenever you uninstall any component, place it on a grounded antistatic pad or in
the bag that came with the component.
• 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.

• The AM4 socket has a different pinout design. Ensure that you use a CPU designed
for the AM4 socket.
• The CPU fits in only one correct orientation. DO NOT force the CPU into the socket
to prevent bending the connectors on the socket and damaging the CPU.
• Ensure that all power cables are unplugged before installing the CPU.

Chapter 1: Product Introduction
2. DIMM slots
The motherboard comes with Dual Inline Memory Modules (DIMM) slots designed for DDR4
(Double Data Rate 4) memory modules.
A DDR4 memory module is notched differently from a DDR, DDR2, or DDR3 module. DO
NOT install a DDR, DDR2, or DDR3 memory module to the DDR4 slot.
Recommended memory configurations
Chapter 1

Memory configurations
You may install 4 GB, 8 GB, 16 GB, and 32 GB unbuffered and non-ECC DDR4 DIMMs into
the DIMM sockets.
Chapter 1
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 configuration. Any excess
memory from the higher-sized channel is then mapped for single-channel operation.
• The default memory operation frequency is dependent on its Serial Presence Detect
(SPD), which is the standard way of accessing information from a memory module.
Under the default state, some memory modules for overclocking may operate at a
lower frequency than the vendor-marked value.
• For system stability, use a more efficient memory cooling system to support a full
memory load or overclocking condition.
• Always install the DIMMS with the same CAS Latency. For an optimum compatibility,
we recommend that you install memory modules of the same version or data code
(D/C) from the same vendor. Check with the vendor to get the correct memory
modules.
• Visit the ASUS website for the latest QVL.

Unplug the power cord before adding or removing expansion cards. Failure to do so may
cause you physical injury and damage motherboard components.
