4. Setup Instructions
Before starting, ensure your system is powered off and unplugged from the wall outlet. Wear an anti-static wrist strap to prevent electrostatic discharge (ESD) damage.
4.1. CPU Installation
- Locate the LGA 2011-3 socket on the motherboard.
- Open the CPU retention mechanism by pushing down and out on the lever(s).
- Carefully align the triangular mark on your Intel LGA 2011-3 processor with the corresponding mark on the socket.
- Gently place the CPU into the socket. Do not force it.
- Close the retention mechanism by pushing the lever(s) back into place until they click.
- Apply a thin, even layer of thermal paste to the top of the CPU.
- Install your CPU cooler according to its manufacturer's instructions.
4.2. Memory (RAM) Installation
The motherboard supports four-channel DDR4 memory. For optimal performance, install memory modules in matched pairs or quads.

- Open the clips at both ends of the DDR4 memory slots.
- Align the notch on the memory module with the key in the DIMM slot.
- Press down firmly on both ends of the memory module until the clips snap into place.
- Ensure all four slots are populated for four-channel operation if desired, or follow your specific memory configuration.
4.3. Storage Device Installation
4.3.1. NVME M.2 SSDs

- Locate the three NVME M.2 slots on the motherboard.
- Remove the M.2 standoff screw from the desired slot.
- Insert the M.2 SSD into the slot at a 30-degree angle.
- Push the SSD down and secure it with the standoff screw.
4.3.2. SATA Drives
- Connect one end of a SATA data cable to one of the six SATA 3.0 ports on the motherboard.
- Connect the other end of the SATA data cable to your SATA hard drive or SSD.
- Connect a SATA power cable from your power supply to the SATA drive.
4.4. Expansion Card Installation (PCIe)
- Locate the PCIe 3.0 X16 slot (for graphics cards) and the PCIe 3.0 X1 slot.
- Remove the corresponding expansion slot cover from your PC case.
- Align your expansion card with the slot and press down firmly until it is seated correctly.
- Secure the card with a screw to the PC case.
4.5. Power Connections
- Connect the 24-pin ATX power connector from your power supply to the 24-pin power socket on the motherboard.
- Connect the 8-pin CPU power connector (EPS12V) from your power supply to the 8-pin CPU power socket near the CPU socket.
- Connect any additional power cables required by your graphics card or other components.
4.6. Front Panel Connectors
Refer to Figure 2 for the location of front panel headers. Connect your case's power button, reset button, HDD LED, power LED, and front panel USB/audio connectors to the corresponding pins on the motherboard.
4.7. TPM Module Installation (Optional)
If you plan to use a Trusted Platform Module (TPM), ensure you have an ASUS 14-pin TPM2.0 accessory. Locate the TPM interface on the motherboard (refer to Figure 2) and carefully install the module according to its instructions.
5. Operating Instructions
5.1. First Boot
- After all components are installed and connected, ensure all cables are secure.
- Connect your monitor, keyboard, and mouse.
- Plug in the power cord and turn on your power supply.
- Press the power button on your PC case.
- The system should power on and display the BIOS/UEFI splash screen.
5.2. BIOS/UEFI Setup
During startup, press the designated key (usually DEL or F2) to enter the BIOS/UEFI setup utility. Here you can:
- Configure boot order for your operating system installation.
- Adjust memory timings and frequencies.
- Monitor system temperatures and fan speeds.
- Enable or disable various onboard peripherals.
- Set up security features like TPM.
Save your changes and exit the BIOS/UEFI to continue booting into your operating system installer or existing OS.
6. Maintenance
- Cleaning: Periodically clean dust from your PC case and motherboard components using compressed air. Ensure the system is powered off and unplugged before cleaning.
- BIOS Updates: Check the manufacturer's website for BIOS/UEFI updates. Updates can improve stability, compatibility, and performance. Follow the update instructions carefully to avoid damaging the motherboard.
- Component Checks: Regularly inspect cables and connections to ensure they are secure.
7. Troubleshooting
- No Power/No Boot:
- Ensure the power supply is connected correctly (24-pin ATX and 8-pin CPU).
- Verify that your power supply meets the minimum 500W requirement.
- Check front panel power button connections.
- No Display:
- Ensure your graphics card is properly seated in the PCIe X16 slot and has adequate power.
- Check monitor connections and input source.
- If using integrated graphics (if available on your CPU/motherboard combination), ensure your monitor is connected to the correct port.
- Memory Issues:
- Ensure memory modules are fully seated in their slots.
- Try booting with only one memory stick to isolate a faulty module.
- Use memory from international brands like Samsung, Kingston, Sandy, Micron, or Hynix, as other brands may have compatibility issues.
- Diagnostic Card (POST Codes): The integrated diagnostic card displays two-digit codes during startup. Refer to the motherboard's detailed manual (if available from the manufacturer) or online resources for the meaning of specific POST codes to identify the component causing the issue.
- CMOS Battery: The motherboard requires a CR2032 CMOS battery (not included in shipment due to logistics restrictions). If you experience issues with BIOS settings not saving or incorrect time/date, ensure a fresh battery is installed.
8. User Tips
- Power Supply: Always use a reputable brand power supply with at least 500W to ensure stable operation, especially with powerful CPUs and graphics cards.
- Memory Compatibility: For best results and stability, stick to well-known international brands for your DDR4 memory modules.
- TPM Module: If you plan to use Windows 11 or other security features requiring TPM, ensure you acquire the correct ASUS 14-pin TPM2.0 module.
- NVME Cooling: For sustained high performance from NVME M.2 SSDs, consider adding aftermarket heatsinks if your SSDs do not come with them, especially if your case airflow is limited.
