2. Hardware Installation
This section will guide you through the installation of the motherboard. The
topics covered in this section are:
Preparing the motherboard
nstalling the CPU
nstalling the CPU fan
nstalling the memory
nstalling the motherboard
Connecting cables and setting switches
2.1. Safety Instructions
To reduce the risk of fire, electric shock, and injury, always follow basic
safety precautions.
Remember to remove power from your computer by disconnecting the AC
main source before removing or installing any equipment from/to the
computer chassis.
2.2. Preparing the Motherboard
The motherboard shipped in the box does not contain a CPU or memory.
You need to purchase a CPU, a CPU fan assembly, and memory to complete
this installation.
2.2.1. Install ng the CPU
Be very careful when handling the CPU. Make sure not to bend or break any
pins on the back. Hold the processor only by the edges and do not touch the
bottom of the processor.
Use the following procedure to install the CPU onto the motherboard.
1. Unhook the socket lever by pushing down and away from the socket.
2. Lift the load plate. There is a protective socket cover on the load plate to
protect the socket when there is no CPU installed.
3. Remove the protective socket cover from the load plate.
4. Remove the processor from its protective cover, making sure you hold it
only by the edges.
t is a good idea to save the cover so that whenever you remove the CPU,
you have a safe place to store it.
5. Align the notches in the processor with the notches on the socket.
6. Lower the processor straight down into the socket with out tilting or
sliding it into the socket
Make sure the CPU is fully seated and level in the socket.

8
7. Close the load plate over the CPU and press down while you close and
engage the socket lever.
8. There are many different fan types that can be used with this
motherboard. Follow the instruction that came with you fan assembly.
Be sure that the fan orientation is correct for your chassis type and your
fan assembly.
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!

2.3. Installing Memory DIMMs
Your new motherboard has 2 slots for DDR4 memory. They support dual
channel DDR4 memory technology. There must be at least one memory
bank populated to ensure normal operation. Use the following the
recommendations for installing memory.
1 D MM: nstall into D MM1. You can install the D MM into any slot,
however, slot 1 is preferred.
2D MMs: nstall into D MM1&D MM2 slots or D MM-2&D MM-4
slots, to build dual channel。
Use the following procedure to install memory D MMs into the slots on the
motherboard. Note that there is only one gap near the center of the D MM
slot. This slot matches the slot on the memory D MM to ensure the
component is installed properly.
Unlock a D MM slot by pressing the module clips outward.
Align the memory module to the D MM slot, and insert the module
vertically into the D MM slot. The plastic clips at both sides of the
D MM slot automatically lock the D MM into the connector.
2. . Installing the Motherboard
The sequence of installing the motherboard into the chassis depends on the
chassis you are using and if you are replacing an existing motherboard or
working with an empty chassis. Determine if it would be easier to make all
the connections prior to this step or to secure the motherboard and then
make all the connections. Use the following procedure to install the /O

10
shield and secure the motherboard into the chassis.
Be sure that the CPU fan assembly has enough clearance for the chassis
covers to lock into place and for the expansion cards. Also make sure the
CPU Fan assembly is aligned with the vents on the covers.
2.5. Installing the I/O Shield
The motherboard kit comes with an /O shield that is used to block radio
frequency transmissions, protects internal components from dust and foreign
objects, and promotes correct airflow within the chassis.
Before installing the motherboard, install the /O shield from the inside of
the chassis. Press the /O shield into place and make sure it fits securely. f
the /O shield does not fit into the chassis, you would need to obtain the
proper size from the chassis supplier.
2.6. Securing the Motherboard into the Chassis
Most computer chassis have a base with mounting studs or spacers to allow
the mother board to be secured to the chassis and help to prevent short
circuits. f there are studs that do not align with a mounting hole on the
motherboard, it is recommended that you remove that stud to prevent the
possibility of a short circuit.
1. Carefully place the motherboard onto the studs/spacers located inside
the chassis.
2. Align the mounting holes with the studs/spacers.
3. Align the connectors to the /O shield.
4. Ensure that the fan assembly is aligned with the chassis vents according
to the fan assembly instruction.
5. Secure the motherboard with a minimum of eight-to-ten screws.
2.7. Connecting Cables and Setting Switches
This section takes you through all the connections and switch settings
necessary on the motherboard. This will include:
