2-3 Installing the CPU and CPU Cooler
Read the following guidelines before you begin to install the CPU:
•Make sure that the motherboard supports the CPU.
(Go to GIGABYTE's website for the latest CPU support list.)
•Always turn off the computer and unplug the power cord from the power outlet before installing the
CPU to prevent hardware damage.
•Locate the pin one of the CPU. The CPU cannot be inserted if oriented incorrectly. (Or you may
locate the notches on both sides of the CPU and alignment keys on the CPU socket.)
•Apply an even and thin layer of thermal grease on the surface of the CPU.
•Do not turn on the computer if the CPU cooler is not installed, otherwise overheating and damage
of the CPU may occur.
•Set the CPU host frequency in accordance with the CPU specications. It is not recommended
that the system bus frequency be set beyond hardware specications since it does not meet the
standard requirements for the peripherals. If you wish to set the frequency beyond the standard
specications, please do so according to your hardware specications including the CPU, graphics
card, memory, hard drive, etc.
Please visit GIGABYTE's website for details on hardware installation.

•Memory modules have a foolproof design. A memory module can be installed in only one direction.
If you are unable to insert the memory, switch the direction.
DualChannelMemoryConguration
This motherboard provides four memory sockets and supports Dual Channel Technology. After the memory
is installed, the BIOS will automatically detect the specications and capacity of the memory. Enabling Dual
Channel memory mode will double the original memory bandwidth.
The four memory sockets are divided into two channels and each channel has two memory sockets as following:
Channel A: DDR5_A1j/DDR4_A1klm, DDR5_A2j/DDR4_A2klm
Channel B: DDR5_B1j/DDR4_B1klm, DDR5_B2j/DDR4_B2klm
Due to CPU limitations, read the following guidelines before installing the memory in Dual Channel mode.
1. Dual Channel mode cannot be enabled if only one memory module is installed.
2. When enabling Dual Channel mode with two or four memory modules, it is recommended that memory of
the same capacity, brand, speed, and chips be used.
When installing a single memory module, we recommend that you install it in the DDR5_A2j/
DDR4_A2klm or DDR5_B2j/DDR4_B2klm socket.

1/2) ATX_12V_2X4/ATX (2x4 12V Power Connector and 2x12 Main Power Connector)
With the use of the power connector, the power supply can supply enough stable power to all the components
on the motherboard. Before connecting the power connector, rst make sure the power supply is turned
off and all devices are properly installed. The power connector possesses a foolproof design. Connect the
power supply cable to the power connector in the correct orientation.
The 12V power connector mainly supplies power to the CPU. If the 12V power connector is not connected,
the computer will not start.
To meet expansion requirements, it is recommended that a power supply that can withstand high
power consumption be used (500W or greater). If a power supply is used that does not provide the
required power, the result can lead to an unstable or unbootable system.

The battery provides power to keep the values (such as BIOS congurations, date, and time information)
in the CMOS when the computer is turned off. Replace the battery when the battery voltage drops to a low
level, or the CMOS values may not be accurate or may be lost.
You may clear the CMOS values by removing the battery:
1. Turn off your computer and unplug the power cord.
2. Gently remove the battery from the battery holder and wait for one
minute. (Or use a metal object like a screwdriver to touch the positive
and negative terminals of the battery holder, making them short for
5 seconds.)
3. Replace the battery.
4. Plug in the power cord and restart your computer.
•Always turn off your computer and unplug the power cord before replacing the battery.
•Replace the battery with an equivalent one. Damage to your devices may occur if the battery is
replaced with an incorrect model.
•Contact the place of purchase or local dealer if you are not able to replace the battery by yourself
or uncertain about the battery model.
•When installing the battery, note the orientation of the positive side (+) and the negative side (-)
of the battery (the positive side should face up).
•Used batteries must be handled in accordance with local environmental regulations.
23) QFLASH_PLUS (Q-Flash Plus Button)
Q-Flash Plus allows you to update the BIOS when your system is off (S5 shutdown state). Save the latest
BIOS on a USB thumb drive and plug it into the dedicated port, and then you can now ash the BIOS
automatically by simply pressing the Q-Flash Plus button. The QFLED will ash when the BIOS matching

BIOS (Basic Input and Output System) records hardware parameters of the system in the CMOS on the
motherboard. Its major functions include conducting the Power-On Self-Test (POST) during system startup,
saving system parameters and loading operating system, etc. BIOS includes a BIOS Setup program that allows
the user to modify basic system conguration settings or to activate certain system features.
When the power is turned off, the battery on the motherboard supplies the necessary power to the CMOS to
keep the conguration values in the CMOS.
To access the BIOS Setup program, press the <Delete> key during the POST when the power is turned on.
To upgrade the BIOS, use either the GIGABYTE Q-Flash or @BIOS utility.
•Q-Flash allows the user to quickly and easily upgrade or back up BIOS without entering the operating system.
•@BIOS is a Windows-based utility that searches and downloads the latest version of BIOS from the Internet
and updates the BIOS.
For instructions on using the Q-Flash and @BIOS utilities, please navigate to the "Unique Features" page of
GIGABYTE's website and search for "BIOS Update Utilities."
Chapter 3 BIOS Setup
•Because BIOS ashing is potentially risky, if you do not encounter problems using the current
version of BIOS, it is recommended that you not ash the BIOS. To ash the BIOS, do it with
caution. Inadequate BIOS ashing may result in system malfunction.
•It is recommended that you not alter the default settings (unless you need to) to prevent system
instability or other unexpected results. Inadequately altering the settings may result in system's
failure to boot. If this occurs, try to clear the CMOS values and reset the board to default values.
•Refer to the introductions of the battery/clear CMOS jumper in Chapter 2 or navigate to the "BIOS
Setup" page of GIGABYTE's website and search for "Load Optimized Defaults" for how to clear
the CMOS values.
Please visit GIGABYTE's website for details on conguring BIOS Setup.
