Windows 2008 R2 Core Parking

Discussion in 'Windows Home Server' started by Matthijs Vreeken, Sep 7, 2009.

  1. Core parking is a new option in Windows 2008 R2 which allows the Operating
    System to park one or more CPU cores when the processor load is low.
    According to all documentation and multiple blog posts I found; the core
    parking option can be configured using a Group Policy Object.
    Unfortunately none of these resources is specific on the exact location
    where to configure this.
    I have checked all GPO options I could think of, without result.
    Could anyone point me in the right direction, where to configure core
    parking for Windows 2008 r2?
    Many thanks,
    Matthijs

    I can't find it either. I don't think they have the Excel spreadsheet
    out yet with R2 GP settings, maybe once that's out we can find it?

    Thanks, didn't see that.

    I did check the Server 2008 R2 spreadsheet, and I searched for CPU,
    core, parking, ACPI, and I did not find any entry for turning on core
    parking. I wonder what it is called?

  4. Hello,
    There isn't a group policy setting for core parking.
    You can set core parking options with powercfg or via WMI
    Thanks,

    Really? There are a ton of sites saying it's Group Policy. Oh well.

    With regard to powercfg, is there documentation on how to do this? Here
    is the help file, I see nothing about core parking or anything that even
    resembles it...


    POWERCFG <command line options>
    Description:
    This command line tool enables users to control the power settings
    on a system.

    Parameter List:
    -LIST, -L Lists all power schemes in the current user's environment.

    Usage: POWERCFG -LIST

    -QUERY, -Q Displays the contents of the specified power scheme.

    Usage: POWERCFG -QUERY <SCHEME_GUID> <SUB_GUID>

    <SCHEME_GUID> (optional) Specifies the GUID of the power
    scheme
    to display, can be obtained by using
    powercfg -l.
    <SUB_GUID> (optional) Specifies the GUID of the subgroup
    to display. Requires a SCHEME_GUID to be
    provided.

    If neither SCHEME_GUID or SUB_GUID are provided, the settings
    of the current user's active power scheme are displayed.
    If SUB_GUID is not specified, all settings in the specified
    power scheme are displayed.

    -CHANGE, -X Modifies a setting value in the current power scheme.

    Usage: POWERCFG -X <SETTING> <VALUE>

    <SETTING> Specifies one of the following options:
    -monitor-timeout-ac <minutes>
    -monitor-timeout-dc <minutes>
    -disk-timeout-ac <minutes>
    -disk-timeout-dc <minutes>
    -standby-timeout-ac <minutes>
    -standby-timeout-dc <minutes>
    -hibernate-timeout-ac <minutes>
    -hibernate-timeout-dc <minutes>

    Example:
    POWERCFG -Change -monitor-timeout-ac 5

    This would set the monitor idle timeout value to 5 minutes
    when on AC power.

    -CHANGENAME Modifies the name of a power scheme and optionally it's
    description.

    Usage: POWERCFG -CHANGENAME <GUID> <name> <scheme
    description>

    If the description is omitted only the name will be changed.

    -DUPLICATESCHEME
    Duplicates the specified power scheme. The resulting
    GUID which represents the new scheme will be displayed.

    Usage: POWERCFG -DUPLICATESCHEME <GUID> <destination GUID>

    <GUID> Specifies a scheme GUID obtained by using the
    powercfg -l.

    If <destination GUID> is omitted, a new GUID will be
    created for the duplicated scheme.

    -DELETE, -D Deletes the power scheme with the specified GUID.

    Usage: POWERCFG -DELETE <GUID>

    <GUID> obtained by using the LIST parameter.

    -DELETESETTING
    Deletes a power setting.

    Usage: POWERCFG -DELETESETTING <SUB_GUID> <SETTING_GUID>

    <SUB_GUID> Specifies the subgroup GUID.
    <SETTING_GUID> Specifies the power setting guid.

    -SETACTIVE, -S
    Makes the specified power scheme active on the system.

    Usage: POWERCFG -SETACTIVE <SCHEME_GUID>

    <SCHEME_GUID> Specifies the scheme guid.

    -GETACTIVESCHEME
    Retrieve the currently active power scheme.

    Usage: POWERCFG -GETACTIVESCHEME

    -SETACVALUEINDEX
    Sets a value associated with a specified power setting
    while the system is powered by AC power.

    Usage: POWERCFG -SETACVALUEINDEX <SCHEME_GUID> <SUB_GUID>
    <SETTING_GUID>
    <SettingIndex>

    <SCHEME_GUID> Specifies a power scheme GUID and may be
    obtained by using PowerCfg /L.
    <SUB_GUID> Specifies a subgroup of power setting
    GUID and may
    be obtained by using "PowerCfg /Q."
    <SETTING_GUID> Specifies an individual power setting
    GUID and may
    be obtained by using "PowerCfg /Q".
    <SettingIndex> Specifies which of the list of of
    possible values
    this power setting will be set to.

    Example:
    POWERCFG -SetAcValueIndex <GUID> <GUID> <GUID> 5
    This would set the power setting's AC value to the
    5th entry
    in the list of possible values for this power setting.

    -SETDCVALUEINDEX
    Sets a value associated with a specified power setting
    while the system is powered by DC power.

    Usage: POWERCFG -SETDCVALUEINDEX <SCHEME_GUID> <SUB_GUID>
    <SETTING_GUID>
    <SettingIndex>
    <SCHEME_GUID> Specifies a power scheme GUID and may be
    obtained by using PowerCfg /L.
    <SUB_GUID> Specifies a subgroup of power setting
    GUID and may
    be obtained by using "PowerCfg /Q."
    <SETTING_GUID> Specifies an individual power setting
    GUID and may
    be obtained by using "PowerCfg /Q".
    <SettingIndex> Specifies which of the list of possible
    values
    this setting will be set to.

    Example:
    POWERCFG -SetDcValueIndex <GUID> <GUID> <GUID> 5
    This would set the power setting's DC value to the
    5th entry
    in the list of possible values for this power setting.

    -HIBERNATE, -H
    Enables-Disables the hibernate feature. Hibernate
    timeout is not
    supported on all systems.

    Usage: POWERCFG -H <ON|OFF>
    POWERCFG -H -Size <PercentSize>
    -Size Specifies the desired hiberfile size in percentage
    of the
    total memory. The default size cannot be smaller
    than 50.
    This switch will also enable the hiberfile
    automatically.

    -AVAILABLESLEEPSTATES, -A
    Reports the sleep states available on the system
    Attempts to report reasons why sleep states are unavailable.

    -DEVICEQUERY
    Return a list of devices that meet the specified criteria.
