Huaqing Intel C-State is an energy-saving technology, which can reduce power consumption and temperature when CPU is idle. If your Huaqing motherboard supports Intel C-mode function, but you can't find the relevant options, please try the following methods:

1. Confirm BIOS version: Please make sure that your motherboard has been upgraded to the latest BIOS version and supports Intel C status function. You can go to Huaqing official website to download the latest BIOS and update it.

2. View Advanced Settings: After entering the BIOS interface, look for the "Advanced" or "Advanced" option in the menu and expand all submenus under this option. Then look for settings related to CPU and power management, and options like "C-States", "power management" and "processor power management" may appear.

3. Enable C-state: If you find the corresponding option in the above steps, please enable it to use the Intel C-state function. The specific operation mode may vary with different models. Please refer to the motherboard manual or the documents and video tutorials provided by Huaqing official website.

It should be noted that when using the Intel C-State function, the CPU frequency will be dynamically adjusted to adapt to the load change, which may affect the performance and stability. It is suggested to select and configure according to the actual needs, and conduct adequate testing and evaluation.
