Overview of Components

Familiarize yourself with the layout of the motherboard components and connectors.

1. Install CPU & Fan

Follow these steps to correctly install your CPU and its cooling fan:

1. Open the CPU socket lever.
2. Carefully place the CPU into the socket, aligning the golden triangle on the CPU with the triangle on the socket.
3. Close the CPU socket lever to secure the CPU.
4. Install the CPU cooler onto the motherboard, ensuring it makes firm contact with the CPU.
5. Connect the CPU heatsink's 4-pin fan power connector to the 4-pin CPU fan header (CPU_FAN1) on the motherboard.

Important:

• Ensure the motherboard supports your CPU model.
• Always unplug the power cord before installing or removing the CPU.
• Retain the CPU protective cap after installation.
• Do not operate the computer without a CPU cooler installed to prevent damage.
• Apply thermal paste evenly between the CPU and heatsink.
• Do not force the CPU into the socket; ensure the lever is lifted and the CPU is correctly aligned.

2. Install Memory

The motherboard has two DDR3 DIMM slots. Follow these steps:

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 firmly.
3. Flip the latches inwards to lock the memory module in place.

Important:

• Use memory modules of the same capacity, brand, speed, and chips for optimal compatibility.
• Always turn off the computer and unplug the power cord before installing memory.
• Memory modules have a foolproof design; they can only be installed in one direction. Do not force them.
• Dual-Channel mode requires two memory modules to be installed.

3. Install Expansion Cards

The motherboard provides one PCIe 2.0 x16 slot and one PCIe x1 slot for expansion cards.

1. Align the expansion card with the desired PCIe slot.
2. Press the card down firmly until it is fully seated in the slot.
3. Secure the card with a screw to the chassis.

Important:

• Turn off the power supply and unplug the power cable before adding or removing expansion cards.
• Incorrect installation can cause short circuits and damage the card or motherboard.

4. Back Panel Connectors

JAUDIO1 Connector (Front Panel Audio Header)

Connect your front panel audio jacks to this header.

Important: An incorrect connection between the module connector and the motherboard header will make the device unable to work or even damage it.

SATA Connectors (SATA1~4)

The motherboard provides four SATA ports: SATA1 and SATA2 are SATA 3.0 (6Gb/s), while SATA3 and SATA4 are SATA 2.0 (3Gb/s). Each connector supports a single SATA device.

M.2 Slot

The M.2 slot supports 2280 form factor M.2 SSDs (both SATA and NVMe protocols).

1. Insert your M.2 SSD into the M.2 slot at a 30-degree angle.
2. Gently push down the SSD and secure it in place with the provided screw.

JCMOS1: CMOS Discharge

To clear CMOS settings, follow these steps:

1. Initial state: The jumper cap covers pins 1 and 2.
2. Discharge: Move the jumper cap to cover pins 2 and 3. Wait for approximately 3 minutes for the discharge to complete.
3. Restore: Return the jumper cap to its initial state (covering pins 1 and 2).

Important: Always turn off the computer and unplug the power cord from the power outlet before discharging CMOS.

JCOM1: Serial Port Connector

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

ATXPWR1, JATXPWR1: Power Connectors

These connectors provide power to the motherboard. Ensure your power supply is sufficient.

Important: It is recommended to use a power supply that can withstand high power consumption (at least 500W). Insufficient power can lead to an unstable or unbootable system. Ensure the power supply is turned off and all devices are installed before connecting.

CPU_FAN1, SYS_FAN1~3: Fan Connectors

• CPU_FAN1 (4-pin): For the CPU radiator. Supports PWM intelligent speed regulation based on load and temperature.
• SYS_FAN1~3 (3-pin): For system cooling fans. No PWM adjustment capability.

JUSB2, JUSB4: USB 2.0 Connectors

These headers conform to USB 2.0 specification and allow you to connect front panel USB 2.0 ports.

FUSB3: USB 3.0 Connector

This header conforms to USB 3.0 and USB 2.0 specification, allowing you to connect front panel USB 3.0 ports.

Operating

BIOS Setup

The BIOS (Basic Input and Output System) stores hardware parameters in the CMOS. It identifies, configures, tests, and connects computer hardware to the operating system upon startup. Key functions include Power-On Self-Test (POST), saving system parameters, and loading the operating system.

The BIOS Setup program allows users to modify basic system configuration settings and activate certain system features. The motherboard's battery supplies power to the CMOS to retain configuration values when the computer is off.

Important: BIOS items are regularly updated for better system performance. The descriptions provided are for reference only and may vary slightly from the latest BIOS version.

Enter BIOS Setup

To enter the BIOS Setup menu:

• When the computer starts up, repeatedly press the DEL key immediately after powering on.
• If the message disappears before you can press DEL, turn off and restart your computer, or press the Reset button on the case. You can also press Ctrl+Alt+Delete to restart.

Reset BIOS

To restore default BIOS settings:

• Go to BIOS Setup and press F6 to load optimized defaults.
• Alternatively, short the Clear CMOS jumper (JCMOS1) on the motherboard (refer to the JCMOS1 section in Setup for detailed steps).

Important: Be sure the computer is off before clearing CMOS data using the jumper.

Maintenance

• Keep Clean: Regularly clean dust from the motherboard and components using compressed air to prevent overheating and ensure longevity.
• Check Connections: Periodically check all power and data cable connections to ensure they are secure.
• BIOS Updates: While generally not recommended unless experiencing issues, BIOS updates can sometimes improve compatibility or performance. Proceed with caution and follow official instructions.
• CMOS Battery: The CMOS battery (CR2032) maintains BIOS settings. If settings are lost after power-off, the battery may need replacement.

Troubleshooting

• No Power/No Boot:
  • Ensure all power connectors (24-pin ATX, 8-pin CPU) are firmly seated.
  • Verify the power supply is sufficient (recommended 500W or higher).
  • Check front panel connections (F_PANEL1) for correct wiring.
  • Try resetting the CMOS (JCMOS1).
• No Display:
  • Ensure the monitor is connected to the correct video output (VGA or HDMI) on the motherboard or discrete graphics card.
  • Reseat RAM modules. Try booting with one RAM module at a time.
  • Reseat the CPU and check for bent pins.
  • Ensure the CPU cooler is properly installed.
• M.2 SSD Not Detected:
  • Ensure the M.2 SSD is correctly seated in the slot.
  • Check BIOS settings to ensure the M.2 slot is enabled and configured correctly (e.g., NVMe mode if applicable).
  • Verify the M.2 SSD is compatible (supports 2280 form factor, SATA or NVMe protocol).
• System Instability/Crashes:
  • Check CPU and system fan connections and ensure proper cooling.
  • Verify RAM compatibility and stability.
  • Ensure all drivers are up to date.
  • Consider loading optimized BIOS defaults.
• BIOS Flashing Risks: BIOS flashing is potentially risky. It is recommended not to flash the BIOS unless you encounter problems with the current version. Inadequate BIOS flashing may result in system malfunction.

User Tips

• M.2 Compatibility: While some documentation may be confusing, user experience confirms that the M.2 slot on this motherboard supports both SATA and NVMe SSDs. Ensure your M.2 drive is properly seated and configured in BIOS if not immediately recognized.
• Operating System Installation: Users have reported successful installation and operation with Windows 11 (version 25H2). Ensure you have the necessary drivers for your components.
• BIOS Updates: If you encounter issues, check for available BIOS updates from the manufacturer. However, only update if necessary and follow instructions carefully.
• TPM 2.0: If you need TPM 2.0 for operating system compatibility (e.g., Windows 11), check your BIOS settings for an option to enable it. This feature may be listed under Security or Boot options.
