5. Setup Guide
5.1 CPU Installation
- Press the lever with your hand and lift it up.
- Lift the CPU slot buckle cover and remove the black protective cover.
- Align the CPU base with the card slot on top of the CPU, and after confirming it is correct, lower the CPU carefully and place it in place.
- After installation, put down the CPU slot buckle cover and snap back the lever.

6. Operating Instructions
6.1 BIOS Access
- To enter the BIOS setup, press the power button and then repeatedly press the DEL key. Note that the DEL key on the numeric keypad may not work.
- To access the boot menu, press the F11 key during startup.
6.2 Secure Boot and TPM
The motherboard supports Secure Boot and TPM (Trusted Platform Module) functionality. These features enhance system security. Refer to your operating system documentation for details on enabling and configuring these features.
7. Maintenance
7.1 Clearing CMOS
If you encounter system instability or need to reset BIOS settings to default, you can clear the CMOS. Follow these steps:
- Disconnect the motherboard power supply.
- Locate the CMOS clear jumper cap on the motherboard (refer to Figure 8 for general location, or Figure 11 for a close-up).
- Move the jumper cap one position to the left.
- Wait for 3 seconds.
- Put the jumper cap back to its original position.
- Reconnect the motherboard power supply.

8. Troubleshooting
8.1 Common Issues and Solutions
- System not booting: Double-check all power connections (24-pin, 4-pin CPU), RAM installation, and CPU seating. Ensure your display cable is connected to the correct port.
- CPU Fan running at maximum speed: Some users have reported that the CPU fan header may not support fan speed control, causing fans to run at full speed constantly. This may be a limitation of the motherboard's fan control capabilities.
- Storage device not detected: Verify that SATA cables are securely connected. For M.2 SSDs, ensure the M.2 mode jumper is correctly set for either NVMe or SATA mode, depending on your SSD type.
- CPU Pin Bending/Broken: Motherboards undergo strict testing before delivery. If you observe bent or broken CPU pins upon receiving the package, immediately contact customer service and provide a complete unboxing video (including order number) for assistance.
- Secure Boot/TPM issues: Ensure your graphics card is compatible with UEFI when Secure Boot is enabled and CSM (Compatibility Support Module) is disabled in the BIOS. Older graphics cards may require CSM to be enabled.
9. User Tips
- M.2 Jumper: Remember to adjust the M.2 mode jumper cap if you are switching between NVMe and NGFF (SATA) M.2 SSDs.
- CPU Fan Control: Be aware that the CPU fan header might not offer speed control, leading to fans running at full speed. Consider this when selecting your cooling solution.
- UEFI Compatibility: If you plan to use Secure Boot, ensure your graphics card supports UEFI. Some older cards (e.g., pre-GTX 900/10 series) might require CSM to be enabled in BIOS, which can conflict with Secure Boot.
- Unboxing Video: In case of any physical damage, especially to CPU pins, an unboxing video can be crucial for support.
