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 fix it by yourself. Contact a qualified service
technician or your retailer.
Operation safety
• Before installing the motherboard and adding devices on it, 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.
• To avoid short circuits, keep paper clips, screws, and staples away from connectors,
slots, sockets and circuitry.
• Avoid dust, humidity, and temperature extremes. Do not place the product in any area
where it may become wet.
• Place the product on a stable surface.
• If you encounter technical problems with the product, contact a qualified service
technician or your retailer.
• Your motherboard should only be used in environments with ambient temperatures
between 10°C and 35°C.

Product Introduction
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 pin denitions in this chapter are for reference only. The pin names depend on the
location of the header/jumper/connector.

The Clear CMOS header allows you to clear the Real Time Clock (RTC) RAM
in the CMOS, which contains the date, time, system passwords, and system
setup parameters.
To erase the RTC RAM:
1. Turn OFF the computer and unplug the power cord.
2. Short-circuit pin 1-2 with a metal object or jumper cap for about 5-10 seconds.
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.
DO NOT short-circuit the pins except when clearing the RTC RAM. Short-circuiting or
placing a jumper cap will cause system boot failure!
If the steps above do not help, remove the onboard battery and short the two pins again to
clear the CMOS RTC RAM data. After clearing the CMOS, reinstall the battery.
12. COM Port header
The COM (Serial) Port header allows you to connect a COM port module.
Connect the COM port module cable to this header, then install the module to
a slot opening on the system chassis.
The COM port module is purchased separately.

1.3 Central Processing Unit (CPU)
The motherboard comes with an AMD Socket AM5 designed for AMD
Ryzen™ 7000 Series Desktop Processors.
Unplug all power cables before installing the CPU.
• The AM5 socket has a different pinout design. Ensure that you use a CPU designed
for the AM5 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.
• ASUS will not cover damages resulting from incorrect CPU installation/removal,
incorrect CPU orientation/placement, or other damages resulting from negligence by
the user.
Installing the CPU
Apply the Thermal Interface Material to the CPU cooling system and CPU before you install
the cooling system, if necessary.

1.4 System memory
This motherboard comes with two Double Data Rate 5 (DDR5) Dual Inline Memory Module
(DIMM) sockets. The gure illustrates the location of the DDR5 DIMM sockets:
DIMM_A
DIMM_B
Channel Sockets
Channel A DIMM_A
Channel B DIMM_B
A DDR5 memory module is notched differently from a DDR, DDR2, DDR3 or DDR4
module. DO NOT install a DDR, DDR2, DDR3 or DDR4 memory module to the DDR5 slot.
• 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 conguration. Any
excess memory from the higher-sized channel is then mapped for single-channel
operation.
• You may install 8 GB,16 GB, 24 GB, 32 GB, and 48 GB unbuffered, ECC and Non-
ECC DDR5 DIMMs into the DIMM slots.
• 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 efcient memory cooling system to support a full
memory load.
• 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.
• Supported memory types, data rate (speed), and number of DRAM modules vary
depending on the CPU and memory conguration, for more information please refer
to CPU/Memory Support list under the Support tab of product information site or visit
https://www.asus.com/support/.

• Ensure that a USB mouse is connected to your motherboard if you want to use the
mouse to control the BIOS Setup program.

Defaults item under the Exit menu or press hotkey <F5>.
• If the system fails to boot after changing any BIOS setting, try to clear the CMOS and
reset the motherboard to the default value.
