Setup and Installation

Before beginning installation, ensure your workspace is clean and static-free. Handle the motherboard by its edges to avoid damaging components.

1. CPU Installation

• Locate the AM4 CPU socket on the motherboard.
• Lift the load lever on the side of the socket.
• Carefully align the triangular marker on your AMD Ryzen CPU with the marker on the socket.
• Gently place the CPU into the socket. Do not force it.
• Lower the load lever to secure the CPU.

2. Memory (RAM) Installation

• Open the clips on both ends of the DDR4 memory slots.
• Align the notch on the DDR4 memory module with the key in the slot.
• Press down firmly on both ends of the memory module until the clips snap into place.

3. M.2 SSD Installation

• Locate the M.2 slot on the motherboard.
• Remove the M.2 standoff screw.
• Insert the M.2 SSD into the slot at an angle.
• Gently push down the SSD and secure it with the standoff screw.

4. Graphics Card (GPU) Installation

• Open the retention clip on the primary PCIe 4.0 x16 slot.
• Align your graphics card with the slot and press down firmly until it clicks into place.
• Secure the graphics card to your PC case with screws.

5. Power Connections

• Connect the 24-pin ATX power connector from your power supply to the motherboard.
• Connect the 8-pin (or 4+4-pin) CPU power connector to the motherboard.
• Connect any necessary PCIe power cables from your power supply to your graphics card.

Operating Instructions

BIOS Update Procedure

Updating your motherboard's BIOS can improve compatibility, stability, and performance. Follow these steps carefully:

1. Prepare USB Storage Device: Format a USB storage device (e.g., USB flash drive) to FAT32 format. Other boot disks like PE or DOC cannot be used.
2. Download BIOS File: Visit the official MAXSUN support site (www.maxsun.com.cn/en) to download the latest BIOS file for your MS-Terminator B550M motherboard. Unzip the downloaded file.
3. Copy EFI Folder: Copy the entire extracted EFI folder to the root directory of the USB storage device you prepared.
4. Remove Drives: Before updating the BIOS, remove all hard drives (including M.2 and SATA SSDs) from the motherboard.
5. Enter BIOS: Insert your USB storage device into a USB port on the motherboard. Power on the system and repeatedly press the "Delete" key to enter the BIOS interface.
6. Load Optimized Defaults: In the BIOS, press "F9" and then "Enter" to load optimized defaults. Navigate to the "Startup" tab and ensure "Flash Write Protect" is set to "Disabled". Then press "F10" and "Enter" to save and reset.
7. Select USB Boot Device: As the system restarts, repeatedly press the "F11" key to enter the boot device selection menu. Select the USB storage device boot option that starts with "UEFI:".
8. Automatic Update: The system will automatically execute the program to update the BIOS. This process may take a few minutes.
9. Unplug USB: When the screen displays "FS0:\EFI\BOOT>" or "FPT Operation Successful", unplug your USB storage device. Otherwise, the system will repeat the update.
10. Restart and Enter New BIOS: Press "Ctrl+Alt+Delete" at the same time. The system will automatically restart and enter the NEW BIOS.
11. Load Optimized Defaults (New BIOS): In the new BIOS, press "F9" and "Enter" to load optimized defaults. Then press "F10" and "Enter" to save and reset.

Maintenance

Regular maintenance helps prolong the life of your motherboard and ensures stable system operation.

• Dust Removal: Periodically use compressed air to clean dust from the motherboard, CPU cooler, and case fans. Dust accumulation can lead to overheating.
• Check Connections: Ensure all power cables, data cables (SATA, M.2), and component connections (RAM, GPU) are securely seated. Loose connections can cause system instability.
• BIOS Updates: Keep your BIOS updated to the latest version as recommended by MAXSUN to benefit from performance improvements, bug fixes, and enhanced compatibility.
• Software Updates: Regularly update your operating system drivers (chipset, graphics, audio, network) to maintain system health and security.

Troubleshooting

If you encounter issues with your MAXSUN B550 Terminator motherboard, refer to the following common troubleshooting steps:

• No Display/Boot:
  • Check all power connections (24-pin ATX, 8-pin CPU, GPU power).
  • Reseat RAM modules firmly in their slots. Try booting with only one RAM stick.
  • Ensure the graphics card is properly seated and connected.
  • Clear CMOS (Complementary Metal-Oxide-Semiconductor) by removing the CMOS battery for a few minutes or using the clear CMOS jumper (refer to motherboard layout for location).
• System Instability/Crashes:
  • Check CPU and GPU temperatures to ensure they are within safe operating limits.
  • Run memory diagnostic tools to check for RAM errors.
  • Ensure all drivers are up to date.
  • Perform a BIOS update to the latest version (refer to Operating Instructions section).
• Peripheral Not Detected:
  • Verify the peripheral is correctly connected to the appropriate port (USB, SATA, M.2).
  • Check device manager in your operating system for driver issues.
  • Ensure the peripheral is enabled in the BIOS settings.
• BIOS Update Issues:
  • Ensure the USB drive is formatted to FAT32 and the BIOS file is correctly placed in the root EFI folder.
  • Double-check that all hard drives were disconnected before attempting the BIOS update.
  • If the update fails, try a different USB port or a different USB drive.
