Install CPU & Fan
Please install the CPU into the CPU socket as shown below.
Important
- Make sure that the motherboard supports the CPU.
- Always unplug the power cord from the power outlet before installing or removing the CPU to prevent hardware damage.
- Please retain the CPU protective cap after installing the processor.
- Do not turn on the computer if the CPU cooler is not installed, otherwise overheating and damage to the CPU may occur.
- Confirm that the CPU heatsink has formed a tight seal with the CPU before booting your system.
- Apply an even layer of thermal paste (or thermal tape) between the CPU and the heatsink to enhance heat dissipation.
- Whenever the CPU is not installed, always protect the CPU socket pins by covering the socket with a plastic cap.
- Locate the pin one of the CPU socket and the CPU. Once the CPU is positioned into its socket, place one finger down on the middle of the CPU, lowering the locking lever and latching it into the fully locked position.
- Do not force the CPU into the CPU socket before the CPU socket locking lever is lifted up, or damage to the CPU and CPU socket may occur.
- Connect the CPU heatsink’s 4pin fan power connector to the 4pin CPU fan header on the motherboard.
Install Memory
The motherboard provides 8 DDR4 ECC DIMM slots with a maximum capacity of
256GB.
- Wrench the latches on both sides of the memory slot outwards.
- Insert the memory into the slot by aligning it with the notch in the slot.
- Flip the latches on both sides of the slot to lock the memory.
Important
- Make sure that the motherboard supports the memory. It is recommended that memory of the same capacity, brand, speed, and chips be used.
- 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.
- The stability and compatibility of the installed memory module depend on the installed CPU and devices when overclocking.
- This motherboard provides two memory sockets and supports 4 Channel Technology.
4-Channel mode cannot be enabled if only one memory module is installed.
( Note: Server memory and desktop memory cannot be used together.)
Install Expansion Card
The motherboard provides 4 PCI_E 3.0 X16 expansion slot.
Place the expansion card in an available PCI Express slot and press the
expansion card until it is fully inserted into the slot.
Important
- When adding or removing expansion cards, always turn off the power supply and unplug the power supply power cable from the power outlet to prevent hardware damage.
- If the expansion card is not installed correctly, it may cause a short circuit throughout the metal pins, which could burn out the expansion card or the motherboard.

If you want to discharge, please go to the next step. -
JCOMS1 (Discharge)
Pull out the cap to cover ”2” and “3”, and wait for about 3 minutes f or the discharge to complete. -
JCOMS 1(restitute)
After the discharge is completed, restore the initial state of the first step
Important
- Always turn off the computer and unplug the power cord from the power outlet before discharging.

ATXPWR1, JATXPWR1~2: Power Connectors
With the use of the power connector, the power supply can provide enough
stable power to all the components on the motherboard. Before connecting the
power connector, make sure the power supply is turned off and all devices are
properly installed.
Important
- It is recommended that a power supply that can withstand high power consumption be used (at least 500W). If a power supply is used that does not provide the required power, the result can lead to an unstable or unbootable system.

BIOS Setup
BIOS (Basic Input and Output System) records hardware parameters of the system
in the CMOS on the motherboard. BIOS identifies, configures, tests and
connects computer hardware to the OS immediately after a computer is turned
on.
Its major functions include conducting the Power-On Self-Test (POST) during
system startup, saving system parameters and loading the operating system,
etc. BIOS includes a BIOS Setup program that allows the user to modify basic
system configuration 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 configuration values in the CMOS.
Important
- Because BIOS flashing is potentially risky if you do not encounter problems using the current version of BIOS, it is recommended that you not flash the BIOS. To flash the BIOS, do it with caution. Inadequate BIOS flashing may result in systemmalfunction.
BIOS Setup
The default settings offer the optimal performance for system stability in
normal conditions. 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 the system’s failure
to boot.
Important
- BIOS items are regularly updated for better system performance. The items may be slightly different from the latest BIOS; therefore, the description is for reference only.
Enter BIOS Setup
Entering BIOS Setup
When the computer starts up, BIOS enters the self-test process. When the self-
test is completed, the following message is displayed: Press DEL key to enter
Setup Menu. At this time, Press
If this message disappears before you press key, you can turn it off and
then turn on your computer or press
It is recommended to repeatedly press the “Del” key immediately after starting
the computer to ensure that the computer can enter BIOS mode.
Current Version
Important
- Functions may vary depending on the product you have.
Reset BIOS
When you need to restore the default BIOS settings to resolve certain
issues, there are several ways to reset the BIOS:
- Go to BIOS and press F6 to load optimized defaults.
- Short the Clear CMOS jumper on the motherboard.
Important
- Be sure the computer is off before clearing CMOS data. Please refer to the Clear CMOS jumper section for resetting BIOS.
