4. Setup Instructions
Before beginning installation, ensure your power supply is disconnected from the wall outlet.
4.1. CPU Installation
- Carefully open the CPU socket retention mechanism (LGA 2011-3).
- Align the CPU with the socket, ensuring the gold triangle on the CPU matches the triangle on the socket.
- Gently place the CPU into the socket without forcing it.
- Close the retention mechanism to secure the CPU.
- Install the CPU cooler and adapter (included in package) according to its specific instructions.
4.2. RAM Installation
The QIYIDA X99-D4 motherboard features four DDR4 memory slots. Proper installation order is crucial for optimal performance. The grey slots (#1 and #4) have priority.

Figure 4: RAM installation priority diagram and M.2 NVME/NGFF switch
- For 1 RAM module: Install in slot #1 or #4 (grey slot).
- For 2 RAM modules: Install in slot #1 and slot #4 (grey slots).
- For 3 RAM modules: Install in slot #1, slot #4 (grey slots), and either slot #2 or #3.
- For 4 RAM modules: Install in all slots.
- The black RAM slots cannot function alone.
4.3. Storage Installation (M.2 NVME/NGFF & SATA)
- M.2 SSD: Insert your M.2 NVME or NGFF SSD into the designated M.2 slot. Ensure the correct mode (NVME or NGFF) is selected if there is a physical switch or BIOS setting.
- SATA Drives: Connect your SATA 2 or SATA 3 storage devices (HDDs/SSDs) to the SATA 3.0 ports using the provided SATA cables.

4.4. Power Connections
- Connect the 24-pin ATX power cable from your power supply to the main 24-pin power connector on the motherboard.
- Connect the 8-pin CPU power cable from your power supply to the 8-pin CPU power connector on the motherboard.
4.5. Front Panel & Rear I/O Connections
Connect the various cables from your PC case to the corresponding headers on the motherboard. Refer to the diagram below for common connection points:

Figure 6: Detailed diagram of motherboard ports and rear I/O
- Front USB: Ensure the front USB cables are correctly inserted into the designated yellow pin headers.
- Front Panel Connectors: Connect the Power LED, HDD LED, Power Switch (POWER SW), and Reset Switch (RESET SW) cables to their respective pins.
- Rear I/O: Connect peripherals to the PS/2, USB 2.0, USB 3.0, Gigabit Network (RJ45), and Audio ports.
4.6. CMOS Battery Installation
A CR2032 battery (not included due to shipping restrictions) must be installed in the motherboard's battery holder for the computer to start. Ensure correct polarity. Incorrect installation can prevent the system from booting.
5. Operating Instructions
Once all components are correctly installed and connected, you can power on your system. The motherboard will initiate the boot process, and you can then proceed with operating system installation or configuration as needed. Access the BIOS/UEFI settings by pressing the designated key (usually DEL or F2) during startup to configure boot order, memory settings, and other system parameters.
6. Maintenance
- Keep Clean: Regularly clean dust from inside your PC case, especially around the CPU cooler and motherboard components, to prevent overheating.
- BIOS Updates: Check the manufacturer's website for BIOS updates. Update the BIOS only if necessary and follow the instructions carefully to avoid system damage.
- Component Checks: Periodically check all cable connections to ensure they are secure.
7. Troubleshooting
- System Not Starting:
- Ensure a CR2032 battery is installed correctly.
- Verify all power cables (24-pin ATX, 8-pin CPU) are securely connected.
- Check front panel connections (Power SW).
- Confirm your power supply is sufficient (at least 500W recommended).
- Memory Issues:
- Ensure RAM modules are installed in the correct slots and order (refer to Section 4.2).
- Verify that server memory and desktop memory are not mixed.
- Incompatibility:
- Some small brand, bad quality, or ES/QS version CPUs, RAM, or M.2 SSDs may be incompatible. It is recommended to confirm compatibility with the seller before purchase if you are using non-standard components.
- TPM 2.0 / Secure Boot:
- The motherboard supports TPM 2.0. A separate TPM 2.0 module (e.g., MSI 14-pin) may be required and needs to be correctly installed. Check BIOS settings for Secure Boot options.
- BIOS Update for Xeon V4:
- If using a Xeon V4 processor, ensure the BIOS is updated to the latest version that supports it.
User Tips:
- Always prioritize the grey RAM slots (#1 and #4) for memory installation.
- A 500W or higher power supply is recommended for stable operation.
- If experiencing issues with TPM 2.0, ensure the correct 14-pin module is installed and check BIOS settings.
- For optimal performance, ensure your CPU cooler is properly installed and functioning to dissipate heat effectively.
