About video card overclocking

Hello, I need to develop a c# program here. One function is to overclock the graphics card.

I heard from my friend that can use the API reserved in the driver, but I didn’t find the corresponding API. I hope to get help

Thank you for contacting NVIDIA developer forum.
If you are referring to the NVAPI SDK, here’s the link to download the public NVAPI SDK: NVAPI | NVIDIA Developer

However, there is no NVAPI available to overclock the graphics card.
