3. Memory (RAM) Installation
This mainboard supports up to 256GB of DDR4 RAM across 8 slots. Open the retention clips on each side of the memory slot. Align the RAM module with the slot, ensuring the notch on the module matches the key in the slot. Press down firmly on both ends until the clips snap into place.
4. Storage Device Installation
The motherboard provides 2 M.2 NVMe slots (one supports NGFF switch) and 8 SATA 3.0 interfaces.
- M.2 NVMe SSD: Insert the M.2 SSD into the slot at an angle, then gently push it down and secure it with the provided screw.
- SATA Drives: Connect your SATA SSDs or HDDs to the SATA 3.0 ports using SATA data cables. Ensure the power cables from your power supply are also connected to these drives.
5. Graphics Card and Expansion Card Installation
Insert your graphics card into one of the PCIe x16 slots. For other expansion cards (e.g., sound cards, network cards), use the available PCIe x1 slots. Ensure cards are fully seated and secured with the case's retention mechanism.
6. Power Supply Connections
Connect the 24-pin ATXPWR connector from your power supply to the main power socket on the motherboard. Also, connect the two 8-pin ATX_CPU power connectors to their respective sockets near the CPUs.
7. Connecting Peripherals
Connect your keyboard, mouse, monitor, and other peripherals to the appropriate ports on the rear I/O panel. The motherboard features 6 USB 3.0 and 6 USB 2.0 ports, as well as a Gigabit Ethernet port and audio jacks.

Operating Instructions
Once all components are installed and connected, you can power on your system.
- Initial Boot: Upon first boot, the system may enter the BIOS/UEFI setup utility. Configure basic settings such as date, time, and boot order.
- Operating System Installation: Install your preferred operating system from a bootable USB drive or optical media.
- Driver Installation: After OS installation, install all necessary drivers for the chipset, graphics card, network, and audio. Drivers are typically available from the component manufacturers' websites.
- RAID Configuration: If you plan to use RAID (0/1/5/10) for your storage, configure it within the BIOS/UEFI settings or using a dedicated RAID utility during OS installation.
- Network Connectivity: The Realtek 8111H Gigabit LAN provides stable network access. Ensure the appropriate driver is installed for optimal performance.
- Audio: The Realtek ALC series sound card provides high-fidelity audio. Connect your speakers or headphones to the audio jacks on the rear I/O panel.
Maintenance
Proper maintenance ensures the longevity and stable performance of your motherboard.
- Environmental Conditions: Operate the motherboard within the specified temperature range of -20°C to 60°C and 0-95% relative humidity (non-condensing). Avoid extreme temperatures and high humidity.
- Dust Removal: Regularly clean your computer case and motherboard to prevent dust buildup, which can lead to overheating and component failure. Use compressed air to gently remove dust from fans, heatsinks, and other components.
- Connection Checks: Periodically check all cable connections (power, data, peripherals) to ensure they are secure.
- BIOS/UEFI Updates: Keep your BIOS/UEFI firmware updated to benefit from performance improvements, bug fixes, and compatibility enhancements. Refer to the manufacturer's website for the latest updates and instructions.
Troubleshooting
If you encounter issues with your X99 Dual Mainboard, consider the following general troubleshooting steps:
- No Power/No Boot:
- Ensure all power cables (24-pin ATX, 8-pin CPU) are securely connected.
- Verify the power supply is functioning correctly.
- Check if the power button cable from the case is correctly connected to the motherboard's front panel header.
- No Display:
- Ensure your graphics card is properly seated in its PCIe slot and has adequate power.
- Verify your monitor is connected to the graphics card and is powered on.
- Try booting with only one RAM stick installed.
- Component Not Detected:
- Reseat the component (CPU, RAM, GPU, M.2 SSD, SATA drive).
- Check for bent pins on CPU sockets or damaged connectors.
- Ensure the latest drivers are installed.
- System Instability/Crashes:
- Check CPU and GPU temperatures. Ensure adequate cooling.
- Run memory diagnostic tools to check for faulty RAM.
- Update BIOS/UEFI and all drivers.
