Install CPU & Fan

Please install the CPU into the CPU socket as shown in the diagrams.

Important Notes:

• Ensure the motherboard supports the CPU.
• Always unplug the power cord before installing or removing the CPU.
• Retain the CPU protective cap after installation.
• Do not power on the computer without the CPU cooler installed to prevent overheating.
• Confirm the CPU heatsink forms a tight seal with the CPU.
• Apply an even layer of thermal paste between the CPU and heatsink.
• Protect CPU socket pins with a plastic cap when the CPU is not installed.
• Align the CPU and socket pins correctly. Lower the locking lever to secure the CPU.
• Do not force the CPU into the socket if the locking lever is not lifted.
• Connect the CPU heatsink's 4-pin fan power connector to the CPU_FAN header.

Install Memory

The motherboard provides 4 DDR4 ECC DIMM slots with a maximum capacity of 64GB.

1. Wrench the latches on both sides of the memory slot outwards.
2. Align the memory module with the notch in the slot and insert it.
3. Flip the latches on both sides of the slot to lock the memory.

Important Notes:

• Ensure the motherboard supports the memory. Using memory of the same capacity, brand, speed, and chips is recommended.
• Always turn off the computer and unplug the power cord before installing memory.
• Memory modules have a foolproof design; install in the correct direction.
• Memory module stability and compatibility may depend on the CPU and other devices, especially during overclocking.
• This motherboard supports 4 Channel Technology, which requires at least two memory modules.
• Server memory and desktop memory cannot be used together.

Install Expansion Card

The motherboard provides a PCI Express 3.0 X16 expansion slot. Place the expansion card in an available PCI Express slot and press it until fully inserted.

Important Notes:

• Turn off the power supply and unplug the power cable before adding or removing expansion cards to prevent hardware damage.
• Incorrect installation may cause a short circuit, potentially damaging the card or motherboard.

Back Panel Connectors

The back panel provides the following connectors:

• PS/2*2: For keyboard (purple) and mouse (green).
• USB 2.0: For USB 2.0 devices.
• USB 3.0: For USB 3.0 devices.
• Gigabit LAN: For internet connection up to 1000Mbps/s.
• Audio: Line-in, Line-out, and Mic-in jacks.

Internal Connectors

F_PANEL1 Connector

Connects front panel power and reset buttons, and HDD LED.

Diagram shows connections for +POWER LED-, +HDD LED-, +POWER SW-, +RESET SW-.

SPEAK1 Connector

Connects to a buzzer and speaker.

JAUDIO1 Connector

This connector allows you to connect audio jacks on the front panel.

Important Note: An incorrect connection may cause the device to malfunction or be damaged.

8* SATA 3.0 Connectors

These SATA 3.0 connectors are SATA 6Gb/s interface ports. Each SATA connector supports a single SATA device.

M.2 Slot

Insert your M.2 SSD into the M.2 slot at a 30-degree angle. Secure the M.2 SSD in place with the screw.

Important Note: Always turn off the computer and unplug the power cord before discharging.

JCOM1: Serial Port Connector

The COM connector can provide one serial port via an optional COM port cable.

ATXPWR1, JATXPWR1: Power Connectors

These connectors provide stable power to motherboard components. Ensure the power supply is turned off and devices are installed before connecting.

Important Note: A power supply that can withstand high power consumption (at least 500W) is recommended. Insufficient power can lead to system instability.

CPU_FAN1, SYS_FAN1: Fan Connectors

CPU_FAN is for the CPU radiator with PWM speed regulation. SYS_FAN is for the case fan (3-pin, no PWM adjustment).

JUSB2, JUSB4: USB 2.0 Connectors

These headers conform to USB 2.0 specification for front panel USB 2.0 ports.

FUSB3: USB 3.0 Connector

This header conforms to USB 3.0 and USB 2.0 specifications for front panel USB 3.0 ports.

BIOS Setup

BIOS (Basic Input and Output System) records hardware parameters and manages system startup. It performs the Power-On Self-Test (POST), saves system parameters, and loads the operating system. The BIOS Setup program allows modification of system configuration settings.

The motherboard battery supplies power to the CMOS to retain configuration values when the power is off.

Important Note: BIOS flashing is risky. It is recommended not to flash the BIOS unless encountering problems with the current version. Flash with caution, as inadequate flashing can lead to system malfunction.

BIOS Setup

Default settings offer optimal performance and stability. Altering default settings without necessity may lead to system instability or boot failures.

Important Note: BIOS items are updated periodically for performance improvements. Descriptions are for reference only and may differ slightly from the latest BIOS.

Enter BIOS Setup

When the computer starts, BIOS performs a self-test. Upon completion, a message prompts to press the DEL key to enter the Setup Menu. Press the DEL key to enter BIOS setup.

If the message disappears quickly, restart the computer by turning it off and on, using the reset button, or pressing Ctrl+Alt+Delete.

It is recommended to repeatedly press the DEL key immediately after starting the computer to ensure entry into BIOS mode.

Important Note: Functions may vary depending on the product.

Reset BIOS

To restore default BIOS settings and resolve issues, you can:

• Go to BIOS and press F6 to load optimized defaults.
• Short the Clear CMOS jumper on the motherboard.

Important Note: Ensure the computer is powered off before clearing CMOS data. Refer to the Clear CMOS jumper section for instructions.
