2. Setup and Installation
2.1 Pre-Installation Checks
- Ensure you have a compatible LGA2011-3 Intel Xeon E5-V3/V4 Series processor.
- Verify that your DDR4 RAM modules are compatible with 2133/2400/2666MHz speeds.
- Prepare a suitable radiator for CPU cooling. The motherboard requires a good radiator for proper operation.
- Confirm your power supply has both a 24-pin ATX connector and an 8-pin ATX 12V connector.
2.2 Component Installation
- CPU Installation: Carefully install your LGA2011-3 Intel Xeon processor into the CPU socket. Ensure proper alignment and secure the retention mechanism. Apply thermal paste and install the CPU radiator.
- RAM Installation: Insert DDR4 memory modules into the two available DIMM slots. Ensure they are fully seated until the clips lock into place.
- Storage Device Installation: Connect SATA drives to the 10 SATA 3.0 ports. For M.2 NVMe SSDs, install them into the M.2 slot.
Important Note: The PCIe x1 slot shares its signal with M.2 NVMe slot 2. These two slots cannot be used simultaneously.
- Power Connection: Connect both the 24-pin ATX power connector and the 8-pin ATX 12V power connector from your power supply to the motherboard. Both connections are required for the motherboard to power on.
- Peripheral Connections: Connect necessary peripherals such as keyboard, mouse, and display to the appropriate ports on the rear I/O panel.

3. Operating Instructions
3.1 Initial Power On
After connecting all components and power, press the power button. During the first boot, the motherboard may take a few minutes to detect and read memory information. Please be patient and allow this process to complete.
3.2 BIOS Access
To enter the BIOS setup utility, continuously press the "DEL" key immediately after powering on the system.
3.3 Operating System Installation
The Intel i226-V network card is a newer component. For optimal performance and compatibility, it is recommended to install the newest versions of operating systems with supportable kernels. Compatible systems include:
- pfSense-CE 2.7
- OPNsense 23.x
- pfSense Plus
- OpenWrt
- ESXi
- Proxmox 8.x
- CentOS
- Other Linux and Windows distributions with updated kernel support.
Ensure your chosen operating system version provides native support for the Intel i226-V network controller to avoid driver issues.
4. Maintenance
Proper maintenance ensures the longevity and stable operation of your motherboard.
- Dust Removal: Regularly clean dust from the motherboard and cooling components using compressed air. Ensure the system is powered off and unplugged before cleaning.
- Cooling: Ensure adequate airflow within your chassis. Verify that all fans (CPU, chassis) are functioning correctly and that the CPU radiator is free from obstructions.
- Firmware Updates: Periodically check the manufacturer's website for BIOS/UEFI firmware updates. Apply updates as recommended, following the provided instructions carefully.
- Cable Management: Organize internal cables to prevent obstruction of airflow and to ensure secure connections.
5. Troubleshooting
- System Does Not Power On:
- Verify that both the 24-pin ATX and 8-pin ATX 12V power connectors are securely attached to the motherboard. Both are required.
- Check the power supply unit (PSU) connection to the wall outlet and ensure the PSU switch is in the 'ON' position.
- Ensure the front panel power button is correctly connected to the motherboard's header.
- No Display Output:
- Confirm the monitor is connected to the motherboard's VGA port and is powered on.
- Reseat the RAM modules. Incorrectly seated RAM is a common cause of no display.
- Ensure the CPU is properly installed and the CPU cooler is making good contact.
- Long Boot Time on First Power On:
This is normal. The motherboard takes a few minutes to read memory information during the initial boot sequence. Allow it to complete.
- M.2 NVMe or PCIe x1 Slot Not Working:
Remember that the PCIe x1 slot shares its signal with M.2 NVMe slot 2. Ensure only one of these is in use at a time.
- Network Connectivity Issues:
If experiencing issues with the 2.5GbE ports, ensure your operating system has the latest kernel and drivers that support the Intel i226-V network card. Refer to Section 3.3 for recommended OS versions.
