1.2.1 Before you proceed
Chapter 1
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.

1.2.3 Central Processing Unit (CPU)
This motherboard supports the New 6th Gen Intel® Core™ processors on the LGA1151
package, with memory and PCI Express controllers integrated to support dual-channel (4
DIMM) DDR4 memory and 16 PCI Express 3.0/2.0 lanes.
Ensure that you install the correct CPU designed for LGA1151 socket only. DO NOT install
a CPU designed for LGA155 and LGA1156 sockets in the LGA1151 socket.
• 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

Chapter 1: Product Introduction
Page 27
Memory configurations
You may install 1 GB, 2 GB, 4 GB and 8 GB unbuffered and non-ECC DDR4 DIMMs into the
DIMM sockets.
• Memory module with memory frequency higher than 2133 MHz and its corresponding
timing or the loaded XMP prole is not the JEDEC memory standard. The stability and
compatibility of these memory modules depend on the CPU’s capabilities and other
installed devices.
• 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.
• 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:
a) Use a maximum of 3GB system memory if you are using a 32-bit Windows OS.
b) Install a 64-bit Windows OS when you want to install 4GB or more on the
motherboard.
c) For more details, refer to the Microsoft
com/kb/929605/en-us.
• 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.
• 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. To operate at the vendor-marked
or at a higher frequency, refer to section 3.5 Ai Tweaker menu for manual memory
frequency adjustment.
• For system stability, use a more efcient memory cooling system to support a full
memory load (4 DIMMs) or overclocking condition.

1.2.6 Onboard buttons
Onboard buttons allow you to ne-tune performance when working on a bare or open-
case system. This is ideal for overclockers and gamers who continually change settings to
Chapter 1
enhance system performance.
1. Power-on button (START)
The motherboard comes with a power-on button that allows you to power up or wake
up the system. The button also lights up when the system is plugged to a power source
indicating that you should shut down the system and unplug the power cable before
removing or installing any motherboard component.
2. RESET button (RESET)
Press the reset button to reboot the system.

Chapter 1: Product Introduction
Page 39
3. MemOK! button (MemOK!)
Installing DIMMs that are not compatible with the motherboard may cause system
boot failure, and the DRAM_LED near the MemOK! button lights continuously. Press
and hold the MemOK! button until the DRAM_LED starts blinking to begin automatic
memory compatibility tuning for successful boot.
• Refer to section Onboard LEDs for the exact location of the DRAM_LED.
• The DRAM_LED also lights up when the DIMM is not properly installed. Turn off the
system and reinstall the DIMM before using the MemOK! function.
• The MemOK! button does not function under Windows
• During the tuning process, the system loads and tests failsafe memory settings. It
takes about 30 seconds for the system to test one set of failsafe settings. If the test
fails, the system reboots and test the next set of failsafe settings. The blinking speed
of the DRAM_LED increases, indicating different test processes.
• Due to memory tuning requirement, the system automatically reboots when each
timing set is tested. If the installed DIMMs still fail to boot after the whole tuning
process, the DRAM_LED lights continuously. Replace the DIMMs with ones
recommended in the Memory QVL (Qualied Vendors Lists) in this user manual or at
www.asus.com.
• If you turn off the computer and replace DIMMs during the tuning process, the system
continues memory tuning after turning on the computer. To stop memory tuning, turn
off the computer and unplug the power cord for about 5–10 seconds.
• If your system fails to boot up due to BIOS overclocking, press the MemOK! button
to boot and load the BIOS default settings. A message will appear during POST
reminding you that the BIOS has been restored to its default settings.
• We recommend that you download and update to the latest BIOS version from
www.asus.com after using the MemOK! function.

1.2.7 Onboard LEDs
1. Hard Disk LED (HD_LED)
The Hard Disk LED is designed to indicate the hard disk activity. It blinks when data
is being written into or read from the hard disk drive. The LED does not light up when
there is no hard disk drive connected to the motherboard or when the hard disk drive
does not function.
Q LEDs check key components (CPU, DRAM, VGA card, and booting devices) in
sequence during motherboard booting process. If an error is found, the corresponding
LED ashes until the problem is solved. This user-friendly design provides an intuitive
way to locate the root problem within seconds.

3.1 Knowing BIOS
The new ASUS UEFI BIOS is a Unied Extensible Interface that complies with UEFI
architecture, offering a user-friendly interface that goes beyond the traditional keyboardonly BIOS controls to enable a more exible and convenient mouse input. You can easily
navigate the new UEFI BIOS with the same smoothness as your operating system. The
term “BIOS” in this user manual refers to “UEFI BIOS” unless otherwise specied.
BIOS (Basic Input and Output System) stores system hardware settings such as storage
device conguration, overclocking settings, advanced power management, and boot
device conguration that are needed for system startup in the motherboard CMOS. In
normal circumstances, the default BIOS settings apply to most conditions to ensure
optimal performance. DO NOT change the default BIOS settings except in the following
circumstances:
• An error message appears on the screen during the system bootup and requests you to
run the BIOS Setup.
• You have installed a new system component that requires further BIOS settings or
update.
Inappropriate BIOS settings may result to instability or boot failure. We strongly
