Hello,

Could you tell us the way to get the information of the rotation speed for RTX4000?

We’re trying to get the information by using the following API.
NvAPI_GPU_GetTachReading()

In case of Quadro P5000, we can get the information propery.
However, in case of Quadro RTX4000, the API function returns the error code (-104(not support)).

Best Regards,
NY

Dear @nomoto-y -san,

We have provided the relevant NvAPI via the NDA SDK from r460. I see that you were already in communication with an NVIDIA representative, over email. Could you please check on the same thread for more information related to the updated SDK?

Once you get the necessary information, kindly update here so that I can close this topic.

Thank you.
