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.

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.

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 ATX 12V Specication 2.0 (or later version) and provides
a minimum power of 350 W.
• 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.
CPU and chassis fan connectors (4-pin CPU_FAN, 4-pin CHA_FAN)
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.
Intel®LGA1151 CPU socket
Install Intel®LGA1151 CPU into this surface mount LGA1151 socket, which is
designed for 8th Generation Intel®Core™ i7 / i5 / i3, Pentium®, and Celeron®
processors.
For more details, refer to Central Processing Unit (CPU).
DDR4 DIMM slots
Install 2 GB, 4 GB, 8 GB, and 16 GB non-ECC DDR4 DIMMs into these DIMM sockets.
For more details, refer to System memory.
Intel®H310 Serial ATA 6.0Gb/s connectors (7-pin SATA6G_1~3)
These connectors connect to Serial ATA 6.0 Gb/s hard disk drives via Serial ATA
6.0 Gb/s signal cables.

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.

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.
Speaker connector (4-pin SPEAKER)
This 4-pin connector is for the chassis-mounted system warning speaker. The
speaker allows you to hear system beeps and warnings.
System panel connector (10-1 pin F_PANEL)
This connector supports several chassis-mounted functions.
USB 3.1 Gen1 connector (20-1 pin U31G1_12)
Connect a USB 3.1 Gen1 module to this connector for additional USB 3.1 Gen1
front or rear panel ports. This connector complies with USB 3.1 Gen1 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 connector (10-1 pin USB914)
Connect a USB module cable to this connector, then install the module to a slot
opening at the back of the system chassis. This USB connector complies with USB
2.0 specications and supports up to 480Mbps connection speed.
Front panel audio connector (10-1 pin AAFP)
This connector is for a chassis-mounted front panel audio I/O module that supports
HD Audio. Connect one end of the front panel audio I/O module cable to this
connector.
• We recommend that you connect a high-denition front panel audio module to this
connector to avail of the motherboard’s high-denition audio capability.
• If you want to connect a high-denition front panel audio module to this connector,
set the Front Panel Type item in the BIOS setup to [HD Audio].

ports for faster and better performance from your USB 3.1 Gen1 devices.
• Due to the design of the Intel®300 series chipset, all USB devices connected to the
USB 2.0 and USB 3.1 Gen1 ports are controlled by the xHCI controller. Some legacy
USB devices must update their rmware for better compatibility.

Central Processing Unit (CPU)
This motherboard comes with a surface mount LGA1151 socket
designed for 8th Generation Intel®Core™ i7/ i5/ i3, Pentium®and
Celeron®processors.
Unplug all power cables 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.
• 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
LGA1151 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.

Channel B DIMM_B1*
• 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.
System memory
Overview
This motherboard comes with two Double Data Rate 4 (DDR4) Dual Inline Memory Module
(DIMM) sockets. The gure illustrates the location of the DDR4 DIMM sockets:
• According to Intel®CPU spec, DIMM voltage below 1.35V is recommended to protect
the CPU.
• Due to the memory address limitation on 32-bit Windows®OS, when you install 4GB
or more memory on the motherboard, the actual usable memory for the OS can be
about 3GB or less. For effective use of memory, we recommend that you do any of the
following:
- Use a maximum of 3GB system memory if you are using a 32-bit Windows®OS.
- Install a 64-bit Windows®OS if you want to install 4GB or more on the
motherboard.
- For more details, refer to the Microsoft®support site at http://support.microsoft.
com/kb/929605/en-us.
• Memory modules with memory frequency higher than 2133 MHz and its corresponding
timing or the loaded X.M.P. Prole is not the JEDEC memory standard. The stability
and compatibility of these memory modules depend on the CPU’s capabilities and
other installed devices.
• 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 efcient memory cooling system to support a full
memory load (2 DIMMs).
• Refer to www.asus.com for the latest Memory QVL (Qualied Vendors List).
