2.3 Memory (RAM) Installation
This motherboard supports 4-channel DDR4 memory. Insert DDR4 memory modules into the DIMM slots, ensuring the notch on the module aligns with the key in the slot. Press down firmly on both ends of the module until the retaining clips snap into place. The motherboard supports memory types DDR4 3000/2666/2400/2133 MHz, with a maximum capacity of 64GB.
Note: Server memory (ECC) and desktop memory cannot be used together. Ensure you use the correct type of memory for your system.
2.4 Storage Device Installation (M.2 and SATA)
The motherboard includes M.2 slots that support both NVMe and SATA M.2 interface types, offering data transfer speeds up to 32Gbps. Install your M.2 SSD by inserting it into the M.2 slot and securing it with the provided screw. For SATA drives, connect them to the SATA 3.0 ports using SATA data cables and connect power from your power supply.

3. Operating Instructions
Once all components are installed and connections are secure, you can power on your system. The Cuifati X99 motherboard is compatible with Windows 10 and other modern operating systems.
3.1 Initial Boot and BIOS Access
Upon first boot, the system may enter the BIOS/UEFI setup utility. You can typically access the BIOS by pressing the DEL or F2 key during startup. Within the BIOS, you can configure boot order, system time, and other advanced settings. Save and exit the BIOS to proceed with operating system installation.
3.2 Driver Installation
After installing your operating system, it is crucial to install the necessary drivers for the motherboard's components, including chipset, LAN (RTL8111G Gigabit LAN Card), audio, and USB controllers. These drivers are typically provided on a CD/DVD included with the motherboard or can be downloaded from the manufacturer's website. Proper driver installation ensures optimal performance and stability.
3.3 Network Connectivity
The integrated RTL8111G Gigabit LAN card provides a stable and fast network connection. Connect an Ethernet cable from your router or modem to the LAN port on the motherboard's rear I/O panel. Ensure the LAN driver is installed for proper functionality.
4. Maintenance
Regular maintenance helps ensure the longevity and stable operation of your motherboard and overall system.
- Dust Removal: Periodically clean dust from inside your computer case, especially from fans (CPU cooler, case fans, GPU fans) and heatsinks. Use compressed air for best results.
- Component Contact Cleaning: If you experience issues, gently wipe the metal contacts on the motherboard, memory modules, CPU, and graphics card with a rubber eraser to improve contact and resolve potential poor connection issues.
- BIOS Updates: Check the manufacturer's website for BIOS updates. BIOS updates can improve compatibility, stability, and performance. Follow the update instructions carefully.
- Driver Updates: Keep your system drivers updated to ensure optimal performance and compatibility with new software and hardware.
5. Troubleshooting
This section addresses common issues you might encounter and provides potential solutions.
5.1 No Display, No Power On, or No Screen
- Check Power Connections: Ensure the 24-pin ATX and 8-pin CPU power connectors are securely seated on the motherboard. Verify your power supply is functioning correctly.
- Reseat Components: Power off and unplug the system. Carefully remove and re-install the CPU, RAM modules, and graphics card. Ensure they are properly seated in their respective slots.
- Clear CMOS: Resetting the CMOS can resolve many boot-related issues. Locate the CMOS battery (a small coin-cell battery) on the motherboard, remove it for 30 seconds, then reinsert it. Alternatively, use the CMOS clear jumper if available (refer to Figure 2.1 for general location).
- Test with Minimal Components: Remove all non-essential components (e.g., extra RAM sticks, expansion cards, storage drives) and try booting with only the CPU, one RAM stick, and the graphics card (if no integrated graphics).
5.2 Network Card or Sound Card Not Working
- Install/Update Drivers: Ensure the latest drivers for the RTL8111G Gigabit LAN card and audio chipset are installed. Check the manufacturer's website for the most recent versions.
- Check BIOS Settings: Verify that the integrated LAN and audio controllers are enabled in the motherboard's BIOS/UEFI settings.
- Check Physical Connections: For network, ensure the Ethernet cable is securely connected. For audio, check speaker/headphone connections to the correct jacks.
5.3 General Instability or Crashes
- Check Temperatures: Ensure your CPU and GPU temperatures are within safe operating limits. Overheating can cause instability. Verify CPU cooler installation.
- Memory Test: Run a memory diagnostic tool (e.g., Windows Memory Diagnostic) to check for faulty RAM modules.
- Power Supply: Ensure your power supply unit (PSU) has sufficient wattage and stable power delivery for all your components.
