3.2 CPU Installation
Follow these steps carefully to install your CPU:
- Press the wire buckle by hand and lift it up. Do not remove the black cover before installing the CPU.
- The motherboard base has 3 bayonets, and the CPU itself has three bayonets. Align them one by one, and then place the CPU gently into the socket.
- Lower the wire buckle that was lifted up, and the black cover on it will pop up automatically. Remember not to remove the black cover before installing the CPU.
- Caution: Do not open the CPU top cover. Do not touch the CPU pins to contact the core. Do not touch the motherboard interface pins.

3.3 Memory (RAM) Installation
The motherboard features two dual-channel DDR3 memory slots. To install RAM:
- Open the clips on both ends of the memory slot.
- Align the notch on the DDR3 memory module with the key in the memory slot.
- Press down firmly on both ends of the memory module until the clips snap into place.

3.4 Storage Device Installation (SATA & M.2)
This motherboard supports both SATA and M.2 storage devices.
- SATA Devices: Connect your SATA SSDs or HDDs to the SATA 3.0 (6Gbps) or SATA 2.0 ports using SATA cables.
- M.2 Devices: Install your SATA M.2 (NGFF M.2) SSD into the dedicated M.2 slot. Ensure it is properly seated and secured with the provided screw. Note that using the M.2 slot may disable one SATA 3.0 port.
3.5 Power Connections
Connect the main 24-pin ATX power connector and the 4-pin CPU power connector from your power supply unit (PSU) to the corresponding ports on the motherboard.
3.6 Front Panel Connections
Connect the front panel headers (Power LED, HDD LED, Power Switch, Reset Switch, USB, Audio) to their respective pins on the motherboard. Refer to the motherboard layout diagram for pin assignments.

4. Operating Instructions
4.1 Initial Boot-up and BIOS Access
After assembling your PC, connect a monitor, keyboard, and mouse. Power on the system. To enter the BIOS/UEFI setup utility, repeatedly press the "Del" key immediately after pressing the power button. Do not wait for the startup logo to appear, as it may be too late.
Within the BIOS, you can configure boot order, system time, and other hardware settings. Save changes before exiting.
4.2 Driver Installation
For optimal performance, install the necessary drivers for your motherboard components (chipset, audio, LAN, etc.).
- If you are using Windows 10, the operating system can often automatically detect and install most drivers.
- For specific drivers or if automatic installation fails, visit the MACHINIST official website or refer to the product page for driver downloads.
4.3 Integrated Graphics Usage
The motherboard supports integrated graphics output via VGA and HDMI. Note that some Intel Xeon E3 V1 and V2 series CPUs do not have integrated graphics. Generally, only CPU models with the suffix "5" (e.g., E3-1245) or Intel Core i3, i5, i7 series (unless they have an "F" suffix) support integrated display.
5. Maintenance
Proper maintenance ensures the longevity and stable operation of your motherboard:
- Dust Removal: Regularly clean dust from the motherboard and other PC components using compressed air. Ensure the system is powered off and unplugged before cleaning.
- Temperature Monitoring: Ensure adequate airflow within your PC case to prevent overheating. Monitor CPU and chipset temperatures using system monitoring software.
- BIOS Battery: The motherboard requires a CR2032 CMOS battery (not included in package). Replace it if you experience issues with BIOS settings resetting or incorrect system time.
- Cable Management: Organize internal cables to improve airflow and prevent interference.
6. Troubleshooting
If you encounter issues after installing the motherboard, consider the following troubleshooting steps:
- No Display/No Boot/No Picture:
- Ensure all power cables (24-pin ATX, 4-pin CPU) are securely connected.
- Reseat the RAM modules. Try booting with only one RAM stick if you have multiple.
- Reseat the CPU. Check for any bent pins on the CPU socket (refer to the "Caution!" image in Setup Guide).
- If using a dedicated graphics card, ensure it is properly seated in the PCIe slot and has adequate power. Try booting without the graphics card if your CPU has integrated graphics.
- Reset CMOS: Locate the CMOS clear jumper or remove the CMOS battery for a few minutes, then reinsert it.
- No Network Card/No Sound Card:
- Ensure drivers are correctly installed. For Windows 10, try updating drivers via Device Manager.
- Check BIOS settings to ensure integrated LAN/Audio are enabled.
- System Instability/Crashes:
- Verify RAM compatibility and ensure it is running at supported frequencies.
- Check CPU and chipset temperatures.
- Ensure all components are properly seated and connections are secure.
If the motherboard is abnormal (e.g., bent CPU pins), do not attempt to repair it without authorization. Contact support and provide an unboxing video if possible before returning the product.
