3.2 Memory Installation
The motherboard features two 240-pin DDR3 SDRAM slots. It supports dual-channel DDR3 memory at speeds of 1066/1333/1600 MHz, with a maximum capacity of 16GB. Ensure memory modules are installed in matching slots for dual-channel operation.
3.3 Storage Installation
- SATA Drives: Connect SATA 2.0 (3Gb/s) or SATA 3.0 (6Gb/s) drives to the available ports. The motherboard includes two ATA2.0 ports and one ATA3.0 port.
- NVME M.2 SSD: The high-speed M.2 interface supports both NVME and NGFF connections. Use the provided jumper to switch between PCIe and ATA3.0 (6GB/s) channels as needed for your M.2 SSD.
3.4 Power Connections
Connect the main 24-pin ATX power connector and the 4-pin ATX 12V power connector from your power supply to the corresponding ports on the motherboard. Ensure connections are firm to maintain circuit reliability.
3.5 Expansion Cards
The motherboard provides one PCI Express x16 slot for a graphics card and one PCI Express x1 slot for other expansion cards.
4. Operating
4.1 Initial Boot and BIOS Configuration
Upon initial power-on, the system will perform a Power-On Self-Test (POST). You may need to enter the BIOS/UEFI setup to configure boot order, system time, and other settings. Refer to your CPU and memory documentation for optimal settings.
4.2 Integrated Graphics Output
The motherboard supports 1080P HD video output via VGA and High Definition Multimedia Interface (HDMI) ports. To utilize these interfaces, your CPU must support integrated graphics.
Figure 8: VGA and HD Multimedia Outputs. This motherboard enables 1080P HD video output without requiring a dedicated graphics card. Your CPU must support integrated graphics to utilize these two interfaces effectively for high-definition display.
4.3 Network Connectivity
The motherboard features an onboard Realtek 10/100 Mbps LAN port for wired network connections.
5. Maintenance
5.1 General Cleaning
Regularly clean your computer's interior to prevent dust buildup, which can lead to overheating and performance issues. Use compressed air to remove dust from fans, heatsinks, and other components. Ensure the system is powered off and unplugged before cleaning.
5.2 BIOS Updates
Periodically check the manufacturer's website for BIOS updates. BIOS updates can improve system stability, add support for new hardware, or fix bugs. Follow the instructions provided by the manufacturer carefully when performing a BIOS update.
6. Troubleshooting
6.1 No Display Output
- Ensure all power cables (24-pin ATX, 4-pin ATX 12V) are securely connected.
- Verify that the monitor cable is connected to the correct video output port (VGA or HDMI) on the motherboard or dedicated graphics card.
- If using integrated graphics, confirm your CPU supports it.
- Reseat the memory modules and any installed expansion cards.
6.2 System Fails to Boot
- Check all power connections to the motherboard, CPU, and storage devices.
- Ensure the CPU is correctly seated in its socket.
