2. Open the clips at both ends of the memory slot.
3. Align the notch on the RAM module with the key in the DIMM slot.
4. Press down firmly on both ends of the RAM module until the clips snap into place. For dual-channel performance, install two identical RAM modules into the designated slots (refer to motherboard diagram for specific slots, usually alternating).

5.3. M.2 NVMe SSD Installation

1. Locate the M.2 slot on the motherboard.
2. Remove the M.2 standoff screw.
3. Insert the M.2 SSD into the slot at a 30-degree angle.
4. Gently push the SSD down and secure it with the standoff screw.

5.4. PCIe Card Installation

1. Locate the PCIe x16 slot for your graphics card or other PCIe slots for expansion cards.
2. Remove the corresponding expansion slot cover from your PC case.
3. Align the card with the slot and press down firmly until it is seated correctly.
4. Secure the card with a screw to the PC case.

5.5. Power Connections

1. Connect the 24-pin ATX power connector from your power supply to the main power socket on the motherboard.
2. Connect the 4-pin ATX 12V power connector from your power supply to the CPU power socket on the motherboard.

5.6. Front Panel and Other Connectors

• Connect your case's front panel connectors (Power LED, HDD LED, Power Switch, Reset Switch) to the corresponding pins on the motherboard. Refer to the motherboard manual for exact pin layout.
• Connect USB 2.0 and USB 3.0 headers from your case to the motherboard.
• Connect SATA data cables from your storage drives to the SATA 3.0 ports on the motherboard.
• Install the CR2032 CMOS battery into its holder on the motherboard.

6. Operating Instructions

6.1. Initial Boot-up and BIOS/UEFI Setup

1. After assembling all components, connect your monitor, keyboard, and mouse.
2. Power on your system. During POST (Power-On Self-Test), repeatedly press the DEL key to enter the BIOS/UEFI setup utility.
3. In the BIOS, you can configure boot order, system time, and other hardware settings. Ensure your storage drive is recognized and set as the primary boot device.
4. Save changes and exit the BIOS to continue booting into your operating system installation media.

6.2. Driver Installation

After installing your operating system, install the necessary drivers for optimal performance:

• Chipset Drivers: Install the latest AMD B450 chipset drivers from the AMD website or MAXSUN support page.
• LAN Driver: Install the Realtek 8111 network card driver for internet connectivity.
• Audio Driver: Install the Realtek ALC897 sound card driver for audio functionality.
• Graphics Drivers: Install drivers for your dedicated graphics card (if applicable) or integrated graphics (if using an APU).

6.3. Overclocking (Optional)

The motherboard supports DDR4 memory overclocking. This feature allows you to run your memory at speeds higher than its default specifications. Access memory settings in the BIOS/UEFI to enable XMP/DOCP profiles or manually adjust timings and frequencies. Proceed with caution, as incorrect settings can lead to system instability.

7. Maintenance

• Dust Removal: Regularly clean dust from the motherboard and components using compressed air. Ensure the system is powered off and unplugged before cleaning.
• BIOS Updates: Check the MAXSUN official website for BIOS/UEFI updates. Updates can improve compatibility, stability, and performance. Follow the provided instructions carefully when updating the BIOS.
• CMOS Battery: If your system loses time or BIOS settings are reset frequently, the CR2032 CMOS battery may need replacement.

8. Troubleshooting

• No Power/No POST: Double-check all power connections (24-pin ATX, 4-pin CPU). Ensure the CPU, RAM, and graphics card are properly seated. Try booting with only essential components (CPU, one RAM stick, GPU).
• No Display: Verify monitor connection and input source. Ensure graphics card is properly seated and powered. If using integrated graphics, ensure your CPU supports it and connect to the motherboard's video output.
• Boot Device Not Found: Check SATA/M.2 connections to your storage drive. Verify boot order in BIOS/UEFI. Ensure your operating system is properly installed on the drive.
• System Instability/Crashes: This can be caused by incompatible drivers, overheating, or unstable overclocking settings. Update drivers, check component temperatures, and reset BIOS settings to default if overclocking.
• Missing CMOS Battery: As noted in the package contents, the CR2032 battery is removed for shipping. If you experience issues with time or BIOS settings not saving, ensure a new CR2032 battery is installed.
