Chapter 2 Hardware installation
Install CPU
Before installing memory, please observe the following warning information:
- Please make sure that the CPU you purchased is compatible with the specifications supported by this motherboard.
- Before installing or removing the CPU, please make sure that the computer power is turned off to prevent damage.
- The CPU is designed with a fool-proof mechanism. If you insert it in the wrong direction, the CPU cannot be inserted. In such cases, do not forcibly install to prevent pin breakage or deformation.
Install CPU
When installing the CPU, firstly pull up the lever on the edge of the CPU
socket at an angle of 90°.
- In the lower-left corner of the front side of the CPU, there will be an arrow that corresponds to the position of the missing pin on the CPU socket.
- Confirm that the CPU has been fully inserted into the CPU socket, and then lower the lever to the sound of “Click”.
- Apply an appropriate amount of thermally conductive silicone grease to the surface of the CPU core to prevent the silicone grease from overflowing onto the socket.
Install memory
Before installing memory, please observe the following warning information:
- Please make sure that the memory you purchased is compatible with the specifications supported by this motherboard.
- Before installing or removing memory, please make sure that the computer power is turned off to prevent damage.
- The memory is designed with a fool-proof mechanism. If you insert the memory in the wrong direction, the memory cannot be inserted. In such a case, please change the insertion direction immediately.
Install memory
- Before installing or removing memory, please turn off the power and unplug the AC power cord.
- Be careful to hold both edges of the memory module, and do not touch its metal contacts.
- Align the gold fingers of the memory module with the memory module slot, and pay attention to the convex point of the gold finger socket to the upper slot in the direction.
- Insert the memory module into the memory slot at an angle of 30°, and then press down the memory module to the sound of “Click”, indicating that the memory has been successfully installed and can be used. (Note: Do not use excessive force when you press down the memory module, so as not to damage the memory)
- To remove the memory module, push the retaining clips on both ends of the DIMM slot outward at the same time, and then remove the memory module.
Memory installation diagram (for reference only):
Note: Static electricity can damage the electronic components of the computer or memory, so before performing the above steps, be sure to briefly touch the grounded metal objects to remove static electricity from your body.

Chapter 3 Installation and setup of jumpers & connectors
Setup description of each jumper
- 2-pin connector: Inserting the jumper cap into two pins will close (short) the connection.
- Removing the jumper cap or inserting it into other pins (reserved for future expansion) will open the connection.
- 3-pin connector: The jumper cap can be inserted into pins 1-2 or 2-3 to close (short) the connection.
How to identify the first pin position of a jumper?
- Please carefully examine the motherboard. Any pin marked with “1” or with a white bold line is the first pin position.
- Examine the solder pads on the back panel. Usually, the square-shaped pad is the first pin.

Chapter 4 BIOS settings
BIOS explanation
This motherboard uses AMI BIOS. The full name of BIOS is Basic Input Output
System. It is stored in a ROM (Read-Only Memory) chip on the computer
motherboard. When you turn on your computer, BIOS is the first program to run.
It mainly has the following functions:
- Initialize your computer and detect hardware, this process is called POST (Power On Self Test).
- Load and run the operating system.
- Provide the lowest and most basic control over your computer hardware.
- Manage your computer through SETUP.
The modified BIOS data will be stored in a battery-maintained CMOS RAM, and the stored data area will not be lost when the power is cut off. Generally, there is no need to modify the BIOS when the system is running normally. If the CMOS data is lost due to other reasons, the BIOS value must be reset.
BIOS setting
This chapter provides information about the BIOS Setup program, allowing users
to configure and optimize system settings by themselves. Some items in the
BIOS that have not been explained too much are not commonly used items. It is
recommended to keep the default settings and not change them arbitrarily
before fully understanding their functions.
You need to run the SETUP program under the following cases:
An error message appears on the screen during the system self-test, and it is
required to enter the SETUP program; You want to change the factory default
settings according to customer characteristics.
Note : Since the BIOS version of the motherboard is constantly being
upgraded, the description of the BIOS in this manual is for reference only. We
do not guarantee that the relevant content in this manual is consistent with
the information you have obtained.
Enter the BIOS setup program
Turn on the power or restart the system, You can see the following information
on the self-test screen, press the key to enter the BIOS setup program.
Control the keys
You can use the arrow key to move the highlighted option, and press
| Control key | Functional description |
