4. Setup Instructions
4.1. Installing Memory (RAM)
When installing memory, ensure the memory module is correctly oriented and fully seated.
- Locate the DIMM slots on the motherboard. There is only one gap in the center of the memory module, which must align with the slot key.
- Insert the memory module vertically into the DIMM slot.
- Push down firmly on both ends of the memory module until the plastic bayonet clips on both sides automatically close and lock the module in place. Ensure the gold finger part of the memory module is fully inserted and not visible.
- Manually check that the memory module is securely locked by the slot clips.

4.2. Installing CPU and CPU Fan
Ensure the CPU is in good condition and the mainboard pins are correct before installation.
- Open the CPU socket retention arm (nail hook).
- Pull the retention arm to the fully open position.
- Remove the plastic protective cover from the CPU socket.
- Carefully insert the CPU into the socket, aligning the CPU notch with the socket key. Hold the bottom edge of the CPU tightly.
- Gently press the retention arm against the bearing plate and close the arm.
- Hook the pressure rod with the hook on the side of the base to secure the CPU.
- Before installing the fan, ensure that the four mounting nails are properly installed on the fan. Align the mounting holes of the fan with those on the mainboard.
- Press the fan down hard until the four nail hooks are jammed into the four holes on the motherboard.
- Press down the four nail hooks to secure the fan. Flip the motherboard to verify that the four nail hooks have been inserted correctly.
- Connect the CPU fan's power cable to the CPU fan power port on the mainboard.
Notice:
If the CPU is not installed, always keep the plastic protective cover over the CPU socket to prevent damage.

5. BIOS Settings
After powering up the computer, the system will perform a Power-On Self-Test (POST). To access the BIOS setup program, press the <DEL> key when the initial information appears on the screen. To quickly boot from a USB flash drive, press <F7>.
If the initial screen disappears before you can press the key, restart the system by pressing the RESET button on the chassis, or by simultaneously pressing <Ctrl>, <Alt>, and <Delete> keys.
5.1. Main Page
The Main page of the BIOS setup utility allows you to configure basic system settings such as time, date, and system language.

6. Operating Instructions
Once all components are installed and connected, you can power on your system. The motherboard will initiate the boot process, and if an operating system is installed on a recognized boot device, it will load automatically.
- Power On: Press the power button on your computer case.
- Initial Boot: The system will display a POST screen. You can enter BIOS setup during this phase.
- Operating System: Ensure your operating system is installed on a bootable drive.
- Drivers: Install all necessary drivers for the motherboard chipset, network, audio, and any other integrated components for optimal performance.
7. Maintenance
7.1. CR2032 Battery Replacement
NOTICE:
Due to logistics reasons, the CR2032 3V battery may not be included with the motherboard. Please purchase a CR2032 3V battery and install it into the battery holder on the motherboard to maintain BIOS settings and system time.
- To Replace: Power off the system and disconnect from power. Locate the circular battery holder on the motherboard. Gently push the small metal clip to release the old battery. Insert the new CR2032 battery with the positive (+) side facing up.
7.2. General Cleaning
- Regularly clean dust from inside your computer case using compressed air.
- Ensure all fans (CPU, case, GPU) are free from obstructions.
- Do not use liquid cleaners directly on motherboard components.
8. Troubleshooting
- No Power/No Boot:
- Verify all power cables (24-pin ATX, 8-pin CPU) are securely connected.
- Ensure your power supply unit (PSU) is at least 500W and functioning correctly.
- Check that the front panel power switch is correctly connected to the motherboard header.
- No Display:
- Ensure your graphics card is properly seated in the PCIe slot and has adequate power.
- Check that your monitor cable is securely connected to the graphics card.
- Try reseating RAM modules.
- Cannot Enter BIOS:
- If the BIOS screen disappears too quickly, restart the system using the chassis RESET button or by pressing <Ctrl> + <Alt> + <Delete> simultaneously, then repeatedly press <DEL> or <F7> (for boot menu) during startup.
- System Instability/Crashes:
- Ensure all drivers are up to date.
