- Align the memory module with the slot, ensuring the notch on the module matches the key in the slot.
- Press down firmly on both ends of the memory module until the clips snap into place.
- M.2 SSD Installation:
- Locate the M.2 slot on the motherboard.
- Insert the M.2 SSD into the slot at an angle.
- Gently push down the SSD and secure it with the provided screw.
- Graphics Card Installation (Optional):
- Locate the PCI-E X16 slot.
- Align your graphics card with the slot and press down firmly until it is fully seated.
- Secure the card to your PC case with a screw.
- SATA Device Connection:
- Connect SATA data cables from your storage devices (HDD/SSD) to the SATA 2.0 ports on the motherboard.
- Ensure power cables from the PSU are connected to your storage devices.
- Power Supply Connection:
- Connect the 24-pin ATX power connector from your power supply unit (PSU) to the main power socket on the motherboard.
- Connect the 8-pin ATX_12V power connector from your PSU to the CPU power socket.
- Front Panel Connections:
- Refer to the motherboard layout diagram (Image 2.1) and your PC case manual to connect the front panel headers (Power SW, Reset SW, HDD LED, Power LED, F_AUDIO, USB 2.0).
3. Operating Instructions
Once all components are installed and connected, you can power on your system.
- Initial Power On: After connecting all necessary cables, press the power button on your PC case. The system should initiate the Power-On Self-Test (POST).
- BIOS/UEFI Access: During the initial boot sequence, repeatedly press the DEL or F2 key (common keys, may vary) to enter the BIOS/UEFI setup utility. Here you can configure boot order, system time, and other advanced settings.
- Operating System Installation: Insert your operating system installation media (USB drive or DVD) and follow the on-screen prompts to install your preferred operating system. Ensure the boot order in BIOS/UEFI is set to prioritize your installation media.
- Driver Installation: After installing the operating system, install the necessary drivers for the motherboard chipset, graphics card, audio, and network. These are typically provided on a CD/DVD with your components or can be downloaded from the manufacturer's websites.
4. Maintenance
Regular maintenance helps ensure the longevity and stable performance of your motherboard.
- Dust Removal: Periodically clean dust from the motherboard and components using compressed air. Ensure the system is powered off and unplugged before cleaning.
- BIOS/UEFI Updates: Check the JMT website for any available BIOS/UEFI updates. Updates can improve compatibility, stability, and performance. Follow the manufacturer's instructions carefully when performing updates.
- Driver Updates: Keep your system drivers updated. Outdated drivers can lead to performance issues or instability.
- Cable Management: Ensure all cables are neatly routed to improve airflow and prevent accidental disconnections.
5. Troubleshooting
If you encounter issues, refer to the following common troubleshooting steps.
- No Power:
- Verify that the 24-pin ATX and 8-pin ATX_12V power connectors are securely seated.
- Check if the power supply unit (PSU) is switched on and functioning correctly.
- Ensure the front panel power button cable is correctly connected to the motherboard header.
- No Display/No POST (Power-On Self-Test):
- Ensure the monitor is connected to the correct display output (motherboard integrated graphics or discrete graphics card).
- Reseat the RAM modules. Try booting with one RAM module at a time if you have multiple.
- Reseat the CPU and check for bent pins in the socket.
- If using a discrete graphics card, reseat it in the PCI-E slot.
- Clear the CMOS (Complementary Metal-Oxide-Semiconductor) by removing the CMOS battery for a few minutes or using the CLR_CMOS header if available (refer to Image 2.1 for location).
- System Instability/Crashes:
- Check CPU and GPU temperatures to ensure they are within safe operating limits.
- Verify that all drivers are up to date.
- Run memory diagnostic tools to check for faulty RAM.
- Ensure the power supply is sufficient for all installed components.
- Operating System Not Booting:
- Check the boot order in BIOS/UEFI to ensure the correct drive is selected.
- Verify that the operating system drive (HDD/SSD) is properly connected and detected by the BIOS/UEFI.
