saeid: Thank you very much for joining the Intel® NUC communities.
We will do further research on this matter in order to confirm if there is an option to disable C and P states from the BIOS.
As soon as I get any updates I will post all the details on this thread.
Any further questions, please let me know.
There is no such an option in BIOS that explicitly says: C states or P States -disable or enable-. The only options available that could help are performance and power related tools but they won’t necessarily disable any of these states.
I would recommend that you check at the operating system level. There are a couple of commands available for Linux* operating systems and for Windows* it usually depends on how “Power Options” à “Advanced Settings” à “Minimum and Maximum processor state” settings are configured.
This is also third party tools that will show you disabled/enable C and P States. This could be useful.
I hope this helps,
