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.

Button/Coin Batteries Safety Information

Chapter 1: Product Introduction

• 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 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 definitions in this chapter are for reference only. The pin names depend on the

location of the header/jumper/connector.

1.1 Before you proceed

Take note of the following precautions before you install motherboard components or

change any motherboard settings.

1. CPU socket

The motherboard comes with a LGA1700 socket designed for Intel® Core™ 14th & 13th

Gen Processors, Intel® Core™ 12th Gen, Pentium® Gold and Celeron® Processors.

LGA1700

• Keep the cap after installing the motherboard. ASUS will process Return

Merchandise Authorization (RMA) requests only if the motherboard comes with the

cap on the CPU socket.

• The product warranty does not cover damage to the socket contacts resulting from

incorrect CPU installation/removal, or misplacement/loss/incorrect removal of the

PnP cap.

2. DIMM slots

The motherboard comes with Dual Inline Memory Modules (DIMM) slots designed for

DDR5 (Double Data Rate 5) memory modules.

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.

Recommended memory configurations

Motherboard User Manual 1-5

Chapter 1

Memory configurations

You may install Non-ECC DDR5 DIMMs into the DIMM sockets.

• You may install varying memory sizes in the DIMM channels. 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.

1-6 Chapter 1: Product Introduction

Chapter 1

3. Expansion slots

Unplug the power cord before adding or removing expansion cards. Failure to do so may

cause you physical injury and damage motherboard components.

To install a PCIe expansion card, please refer to the Motherboard Installation Guide on

the ASUS support site.
