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 0°C and 40°C.

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.

1. CPU socket

The motherboard comes with a LGA1200 socket designed for 10th Gen Intel® CoreTM,
Pentium® Gold and Celeron® Processors.

Chapter 1

LGA1200

• Ensure that you install the correct CPU designed for LGA1200 socket only. DO NOT
install a CPU designed for other sockets on the LGA1200 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.

• Upon purchase of the motherboard, ensure that the PnP cap is on the socket and
the socket contacts are not bent. Contact your retailer immediately if the PnP cap
is missing, or if you see any damage to the PnP cap/socket contacts/motherboard
components. ASUS will shoulder the cost of repair only if the damage is shipment/
transit-related.

• 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 LGA1200 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.

DIMM_A2*

This motherboard comes with four Double Data Rate 4 (DDR4) Dual Inline Memory Module
(DIMM) sockets.

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.

Memory configurations

You may install 2 GB, 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.
