Install CPU & Fan

To install the CPU, align the CPU with the socket and carefully lower the locking lever. Ensure the CPU protective cap is retained after installation. Apply an even layer of thermal paste between the CPU and heatsink for optimal heat dissipation. Connect the CPU heatsink's 4-pin fan power connector to the 4-pin CPU fan header on the motherboard.

Important Notes:

• Ensure motherboard compatibility with the CPU.
• Always unplug the power cord before installation or removal.
• Do not power on the computer without a CPU cooler installed to prevent overheating.
• Confirm a tight seal between the CPU heatsink and CPU.
• Protect CPU socket pins with a plastic cap when the CPU is not installed.
• Do not force the CPU into the socket; lift the locking lever first.

Install Memory

The motherboard has 4 DDR4 ECC DIMM slots supporting up to 64GB of memory.

1. Wrench the latches on both sides of the memory slot outwards.
2. Insert the memory into the slot, aligning it with the notch.
3. Flip the latches on both sides to lock the memory.

Important Notes:

• Use memory of the same capacity, brand, speed, and chips for best results.
• Turn off the computer and unplug the power cord before installing memory.
• Memory modules have a foolproof design; ensure correct orientation.
• Stability and compatibility may depend on CPU and other devices, especially during overclocking.
• The motherboard supports 4-Channel Technology; 4-channel mode requires at least two memory modules.
• Server memory and desktop memory cannot be used together.

Install Expansion Card

The motherboard features two PCI Express 3.0 x16 slots, one PCI Express 3.0 x4 slot, and one PCI Express 3.0 x1 slot. Place the expansion card into an available PCI Express slot and press down until it is fully inserted.

Important Notes:

• Turn off the power supply and unplug the power cable before adding or removing expansion cards.
• Incorrect installation may cause short circuits, potentially damaging the expansion card or motherboard.

Back Panel Connectors

The back panel provides the following connectors:

• PS/2 Ports: For keyboard (purple) and mouse (green).
• USB 3.0 Ports: High-speed USB ports.
• USB 2.0 Ports: Standard USB ports.
• RJ45 LAN Port: Gigabit Ethernet connection.
• Audio Ports: Mic-in, Line-out, Line-in.

RJ45 LAN Port LEDs:

Internal Connectors

F_PANEL1 Connector

This connector is for the front panel controls and indicators, including power switch, reset switch, HDD LED, and power LED.

SPEAK1 Connector

This connector is for the system speaker.

JAUDIO1 Connector

This connector allows connection of front panel audio jacks (Headphone R/L, MIC R/L, MIC Detection, SENSE_SEND).

Important Note: An incorrect connection may prevent the device from working or cause damage.

4* SATA 3.0 Connectors and 2* SATA 2.0 Connectors

These SATA connectors provide interfaces for SATA 6Gb/s (SATA 3.0) and SATA 3Gb/s (SATA 2.0) devices. Each connector supports a single SATA device.

M.2 Slot

Install your M.2 SSD into the M.2 slot at a 30-degree angle and secure it with the provided screw.

JCMOS1: CMOS Discharge

This jumper is used to clear the CMOS settings. The default state covers pins 1 and 2. To discharge, move the cap to cover pins 2 and 3 for approximately 3 minutes. After discharge, restore the cap to the initial state (pins 1 and 2).

Important Note: Ensure the computer is turned off before clearing CMOS data.

JCOM1: Serial Port Connector

The COM connector provides one serial port via an optional COM port cable.

ATXPWR1, JATXPWR1: Power Connectors

These connectors supply power to the motherboard components. It is recommended to use a power supply of at least 500W for stable operation.

Important Note: Using an underpowered supply can lead to system instability.

CPU_FAN1, SYS_FAN1 3: Fan Connectors

CPU_FAN is for the CPU radiator fan, supporting PWM intelligent speed regulation. SYS_FAN is for system cooling fans, typically case fans, and uses 3-pin connectors without PWM adjustment.

JUSB2, JUSB4: USB 2.0 Connectors

These headers conform to the USB 2.0 specification and allow connection of 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) stores hardware parameters in the motherboard's CMOS. It initializes and tests hardware during startup, saving system parameters and loading the OS. The BIOS Setup program allows modification of basic system configuration settings.

Important Note: BIOS flashing is risky. It is recommended not to flash the BIOS unless necessary, and to proceed with caution to avoid system malfunction.

Default BIOS settings are optimized for system stability. Altering them may cause instability or boot failures. BIOS items are updated regularly; refer to the latest BIOS documentation for exact details.

Enter BIOS Setup

When the computer starts, press the Delete key repeatedly during the self-test process to enter the BIOS setup menu. If the prompt disappears, restart the computer or press Ctrl+Alt+Delete.

Reset BIOS

To restore default BIOS settings:

• Press F6 in the BIOS to load optimized defaults.
• Short the Clear CMOS jumper on the motherboard.

Important Note: Ensure the computer is powered off before clearing CMOS data.
