4. Operating Instructions
4.1. First Boot and BIOS/UEFI Setup
Upon first power-on, the system may take longer to boot as it initializes new hardware. Enter the BIOS/UEFI setup by pressing the designated key (usually DEL or F2) during startup. The BIOS is fully translated into English and offers various overclocking features.
Note: The fan control settings in the BIOS may display values rather than traditional fan curves. The boot order might be simplified, booting directly from any detected bootable USB device.
4.2. Driver Installation
After installing your operating system (Windows 10/11 64-bit or Ubuntu 64-bit), install all necessary drivers from the MAXSUN support website or the included driver disc (if applicable). This is crucial for optimal performance, especially for the integrated WiFi 6 and Bluetooth 5.2 functionality.
4.3. Supported Operating Systems
- Windows 10 (64-bit)
- Windows 11 (64-bit)
- Ubuntu (64-bit)
5. Maintenance
5.1. General Care
- Keep the motherboard and PC case free from dust by regularly cleaning with compressed air.
- Ensure adequate airflow within your PC case to prevent overheating.
- Avoid touching motherboard components directly to prevent electrostatic discharge (ESD).
5.2. BIOS Updates
MAXSUN frequently releases BIOS updates to improve compatibility, stability, and performance, especially for newer CPU series (e.g., Ryzen 9000 series). Check the official MAXSUN website for the latest BIOS versions and follow the provided instructions carefully for updating. Incorrect BIOS updates can damage your motherboard.
6. Troubleshooting
- System Fails to Boot:
- Check all power connections (24-pin ATX, 8-pin CPU).
- Reseat RAM modules.
- Ensure CPU is correctly installed.
- Utilize the boot diagnostics lights (if present on your board) to identify the failing component.
- Try clearing the CMOS using the CLR_CMOS button on the rear I/O panel or by temporarily removing the CMOS battery.
- No Display Output:
- Ensure your monitor is connected to the correct display output (motherboard or graphics card).
- Reseat your graphics card.
- Check display cable connections.
- WiFi/Bluetooth Not Working:
- Ensure WiFi antennas are securely connected to the rear I/O panel.
- Install the correct WiFi and Bluetooth drivers from the MAXSUN website.
- Long First Boot Time: This is normal for new AM5 systems as the motherboard initializes memory. Subsequent boots should be faster.
7. User Tips
- BIOS Navigation: The BIOS is user-friendly and in English, offering various overclocking features.
- Fan Control: Be aware that fan control settings in the BIOS might be value-based rather than graphical curves. Adjust as needed for your cooling setup.
- Boot Device Selection: If you need to boot from a USB drive, simply plug it in; the system may automatically prioritize it without needing to change boot order in BIOS.
- RAM Overclocking: This motherboard generally handles RAM overclocking well, with users reporting success with 6000MHz DDR5 memory.
- M.2 Screw: Keep in mind that an M.2 drive screw might not be included in the motherboard packaging, so you may need to source one separately.
- CPU Compatibility: This motherboard is designed for AMD Ryzen AM5 processors (7000 series and newer). It does not support older Ryzen series (3000/4000/5000).
