    How to disable C states and P states in bios for NUC5i7RYB

    saeid

      I have the Intel Visual BIOS version RYBDWi35.86A.0246.2015.0309.1355, and I need to disable all frequency scaling and C states and P states for a certain application. There isn't such an option in this BIOS as far as I can tell.

       

      Any suggestions would be appreciated!

          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.

            Hi saeid:


            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,
