3. Setup
3.1. CPU Installation
Carefully open the CPU socket lever and align your AMD Ryzen processor with the socket, ensuring the golden arrow on the CPU matches the arrow on the socket. Gently place the CPU into the socket without applying force. Close the lever to secure the CPU.
Video 2: Installing AMD Ryzen CPU to Gigabyte AM5 Motherboard. This video demonstrates the process of installing an AMD Ryzen CPU into an AM5 socket motherboard. Note: The motherboard shown in the video is a B650M Eagle WiFi6E, but the CPU installation process for AM5 sockets is generally the same.
3.2. AIO (CPU Cooler) Installation
Before installing the AIO cooler, ensure the correct mounting brackets for your AM5 socket are attached to the cooler pump. Apply thermal paste to the CPU in an X-shaped pattern. Secure the cooler pump to the CPU, ensuring even pressure. Connect the cooler's fan and RGB cables to the appropriate headers on the motherboard.
Video 3: Installing ARCTIC AIO (CPU Cooler) To Motherboard. This video guides you through the steps of installing an All-In-One (AIO) CPU cooler onto a motherboard. Note: The motherboard shown in the video is a B650M Eagle WiFi6E, but the AIO installation process is generally the same.
3.3. RAM Installation
Open the clips on the DDR5 DIMM slots. Align the RAM modules with the slots, ensuring the notch on the module matches the notch in the slot. Press down firmly on both ends of the RAM module until the clips snap into place.
3.4. M.2 SSD Installation
Locate the M.2 slots on the motherboard. The B850M DS3H features EZ-Latch for tool-less installation. Simply align the M.2 SSD with the slot and push it in. Secure it with the EZ-Latch mechanism.

3.5. Power Connections
Connect the 24-pin ATX power connector and the 8-pin CPU power connector from your power supply to the corresponding ports on the motherboard. Ensure all connections are firm.
4. Operating
4.1. BIOS Setup
Upon first boot, access the BIOS by pressing the designated key (usually DEL or F2) during startup. The GIGABYTE BIOS offers an easy-to-use interface for configuring system settings, including memory profiles (CMP/EXPO), boot order, and fan curves.
4.2. Connectivity
The motherboard supports 2.5GbE LAN for high-speed internet. Utilize the various USB ports, including USB-C, for connecting peripherals. The PCIe 5.0 slot is available for high-performance graphics cards.

5. Maintenance
5.1. BIOS Updates
Regularly check the GIGABYTE website for the latest BIOS updates. Updating your BIOS can improve system stability, compatibility, and performance. The motherboard may feature Q-Flash Auto Scan for simplified BIOS updates.
5.2. Cleaning
Periodically clean your computer's interior to prevent dust buildup, which can affect cooling and performance. Use compressed air to remove dust from fans, heatsinks, and other components. Ensure the system is powered off and unplugged before cleaning.
6. Troubleshooting
6.1. Common Issues
- No Boot/No Post: Check all power connections, RAM seating, and CPU installation. Ensure your BIOS is up to date.
- RAM Speed Issues: Verify that your RAM is installed correctly and that the correct EXPO/CMP profile is enabled in the BIOS.
- Fan Issues: Ensure all fan headers are correctly connected. A BIOS update might resolve fan control issues.
6.2. CMOS Reset
If you encounter persistent boot issues or incorrect BIOS settings, you may need to clear the CMOS. Locate the CMOS jumpers (often near the bottom right of the motherboard) or remove the CMOS battery for a few minutes, then reinstall it. This will reset BIOS settings to default.
