Locked How to enable and control CPU core parking

    One of the new features of Windows Server 2008 R2 is the ability to park one or more CPU's cores if the server does not need all the CPU resources. This saves power. To enable core parking and to control it, a Group Policy or local policy should be used according severall blogs and sites.

    However, I have not been able to find any setting which actually configures core parking. Can anyone explain where and how exactly core parking can be set?

      hi there,

      i have went through the documents published from microsoft and all that is written is a equivalent group policy is provided to manage core parking / power management.

      i have gone through the below link worth looking at it

          Hi - According to my personal experience, It depends on the system power managment scheme,  in Balanced Mode -Core parking gets enabled, in High Performance mode- Cpu will never be parked.

          Note: Again.. its just my personal observation.

          Regards

            Hello,
            There isn't a group policy setting for Core Parking.

            RK Jeevan, your observations are correct, it's enabled in Balanced mode and off in High Performance mode
