1-1 Installation Precautions

The motherboard contains numerous delicate electronic circuits and components which can

become damaged as a result of electrostatic discharge (ESD). Prior to installation, carefully read

the user's manual and follow these procedures:

• Prior to installation, do not remove or break motherboard S/N (Serial Number) sticker or

warranty sticker provided by your dealer. These stickers are required for warranty validation.

• Always remove the AC power by unplugging the power cord from the power outlet before

installing or removing the motherboard or other hardware components.

• When connecting hardware components to the internal connectors on the motherboard,

make sure they are connected tightly and securely.

• When handling the motherboard, avoid touching any metal leads or connectors.

• It is best to wear an electrostatic discharge (ESD) wrist strap when handling electronic

components such as a motherboard, CPU or memory. If you do not have an ESD wrist

strap,keepyourhandsdryandrsttouchametalobjecttoeliminatestaticelectricity.

•

Prior to installing the motherboard, please have it on top of an antistatic pad or within an

electrostatic shielding container.

• Before unplugging the power supply cable from the motherboard, make sure the power

supply has been turned off.

• Before turning on the power, make sure the power supply voltage has been set according to

the local voltage standard.

• Before using the product, please verify that all cables and power connectors of your

hardware components are connected.

• To prevent damage to the motherboard, do not allow screws to come in contact with the

motherboard circuit or its components.

• Make sure there are no leftover screws or metal components placed on the motherboard or

within the computer casing.

• Do not place the computer system on an uneven surface

.

• Do not place the computer system in a high-temperature environment.

• Turning on the computer power during the installation process can lead to damage to

system components as well as physical harm to the user.

• If you are uncertain about any installation steps or have a problem related to the use of the

product,pleaseconsultacertiedcomputertechnician.

1-3 Installing the CPU and CPU Cooler

1-3-1 Installing the CPU

A. Locate the alignment keys on the motherboard CPU socket and the notches on the CPU.

Read the following guidelines before you begin to install the CPU:

• Make sure that the motherboard supports the CPU.

• 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specications.Itisnotrecommended

thatthesystembusfrequencybesetbeyondhardwarespecicationssinceitdoesnotmeetthe

standard requirements for the peripherals. If you wish to set the frequency beyond the standard

specifications, please do so according to your hardware specifications including the CPU,

graphics card, memory, hard drive, etc.

Hardware Installation - 12 -

Step 1:

Gently press the CPU socket lever handle down

andawayfromthesocketwithyournger.Then

completely lift the CPU socket lever and the metal

load plate will be lifted as well.

Step 3:

HoldtheCPUwithyourthumbandindexngers.

Align the CPU pin one (triangle marking) with the

pin one corner of the CPU socket (or you may

align the CPU notches with the socket alignment

keys). Gently insert the CPU into position.

Step 5:

Push the CPU socket lever back into its locked

position.

Step 4:

Once the CPU is properly inserted, use one

hand to hold the socket lever and use the other

to lightly replace the load plate. When replacing

the load plate, make sure the front end of the

load plate is under the shoulder screw.

NOTE:

Hold the CPU socket lever by the handle, not by

the lever base position.

Step 2:

Remove the CPU socket cover as shown. Hold

your index finger down on the rear grip of the

socket cover and use your thumb to lift up the

front edge (next to the "REMOVE" mark) and

then remove the cover. (DO NOT touch socket

contacts. To protect the CPU socket, always

replace the protective socket cover when the

CPU is not installed.)

B. Follow the steps below to correctly install the CPU into the motherboard CPU socket.

Before installing the CPU, make sure to turn off the computer and unplug the power cord from

the power outlet power plug to prevent any damage to prevent damage to the CPU.

- 13 - Hardware Installation

1-3-2 Installing the CPU Cooler

Follow the steps below to correctly install the CPU cooler on the motherboard. (The following procedure uses

Intel® boxed cooler as the example cooler.)

Use extreme care when removing the CPU cooler because the thermal grease/tape between the

CPU cooler and CPU may adhere to the CPU. Inadequately removing the CPU cooler may damage

the CPU.

Step 1:

Apply a thin, even layer of thermal paste onto

the surface of the installed CPU.

Step 2:

Before installing the cooler, note the direction of

the arrow sign on the male push pin. (Turning

the push pin along the direction of the arrow is

for removing the cooler, and the opposite

direction is for installing it.)

Step 3:

Place the cooler atop the CPU, aligning the

four push pins through the pin holes on the

motherboard. Push down on the push pins

diagonally.

Step 4:

You should hear a "click" when pushing down

each push pin. Check that the Male and Female

pushpinsarejoinedclosely.(RefertoyourCPU

cooler installation manual for instructions on

installing the cooler.)

Step 5:

After the installation, check the back of the

motherboard. If the push pin is inserted as the

picture above shows, the installation is complete.

Step 6:

Finally, attach the power connector of the CPU

cooler to the CPU fan header (CPU_FAN) on the

motherboard.

1-4 Installing the Memory

Read the following guidelines before you begin to install the memory:

• Make sure that the motherboard supports the memory. It is recommended to use memory of the

same capacity, brand, speed, and chips.

• Always turn off the computer and unplug the power cord from the power outlet before installing

the memory to prevent hardware damage.

• 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.

1-4-1 Installing a Memory

Before installing a memory module, make sure to turn off the computer and unplug the

power cord from the power outlet to prevent damage to the memory module.

Be sure to install DDR4 UDIMMs on this motherboard.

Installation Step:

Step 1. Insert the UDIMM memory module vertically into the UDIMM slot, and push it down.

Step 2. Close the plastic clip at both edges of the UDIMM slots to lock the UDIMM module.

Note: For dual-channel operation, UDIMMs must be installed in matched pairs.

Step 3. Reverse the installation steps when you wish to remove the UDIMM module.

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.

(CPU Fan/System Fan Headers)

The motherboard has one 4-pin CPU fan header (CPU_FAN), and two 4-pin (SYS_FAN) system fan headers.

Most fan headers possess a foolproof insertion design. When connecting a fan cable, be sure to connect

it in the correct orientation (the black connector wire is the ground wire). The motherboard supports CPU

fan speed control, which requires the use of a CPU fan with fan speed control design. For optimum heat

dissipation, it is recommended that a system fan be installed inside the chassis.
