    CPU Parking


    Should not CPUZ show all 4 cores?. i7 920 cpu
    DXDIAG does.
    Performance Monitor shows two cores parked.
    Set for Maximum Performance in power scheme.
    Can you force cores to remain unparked? Windows or Bios.

    There is a option in the bios that limits the cores used, I cant remember what it is but find it and turn it off. I also heard that i7 don't like to be overclocked.

    Right click CPU-Z in task manager (obviously when it is running!) and look at the settings under the affinity option to see how many cores it's set to use by default...

    With the install of retail version, the core and thread numbers became right with CPUZ. I have also found a way to disable core parking since then. Gave me a slight performance boost. Next I disabled HT. Altho cpu numbers dropped a little, it gave me a big ram boost worth 5000MB/s +=.

    ps turned off speed step!

    Here , found this on google :

    For those of you who are using laptops with Windows 7 or Vista installed, you may be disappointed to find out the dual, quad or octal core processor you invested in isn't actually using all of the cores. That's right... out of the box these operating systems do not fully enable the distribution of processes over the cores for certain system configurations. For the most part, these configurations are limited to laptops.

    The reason for disabling multiple cores really comes down to energy consumption. The default power profiles set forth by Microsoft opt for an energy savings based configuration, even when the power settings are set to full performance. Personally, I find it rather obnoxious, as once I disabled core parking, I saw a significant increase in all of my processor intensive tasks.

    How To Disable CPU Core Parking For Dual And Quad Processors:

    1. Copy the following registry key entry between the brackets [ 0cc5b647-c1df-4637-891a-dec35c318583 ].

    2. Select your start button.

    3. In the search box, type 'regedit' and press enter.

    4. Once your registry editor is open, select 'Edit' and 'Find...'.

    5. Paste the above registry key in the box and select 'Find'.

    6. Once it has located it, look for the keys on the right hand side labeled MinValue and MaxValue.

    7. Double click on each value and make sure they are both set to '0'.

    8. Select 'Edit' and 'Find Next...'.

    9. Continue to replace MinValue and MaxValue for each entry until you have replaced them all.

    10. Close the registry editor and shut down your computer.

    11. Power the computer back up.

    12. Core Parking should now be disabled.

    To check whether or not your cores are parked simply press ctrl + alt + del and open the task manager. You can then select the 'Performance' tab and open the 'Resource Monitor...'. Within the resource monitor, select the 'CPU' tab and look at the graphs on the right hand side. None of the CPUs should say, in text, that they are parked. If they do not, then your processor cores are not parked.

    Seems like this would be easier - run and reboot:

    Code:
     
    @echo off
     
    cd %temp%
    powercfg -l | findstr GUID > %temp%\list.txt
    
    FOR /F "tokens=4* delims= " %%i in (%temp%\list.txt) DO powercfg.exe -SETACVALUEINDEX %%i 54533251-82be-4824-96c1-47b60b740d00 0cc5b647-c1df-4637-891a-dec35c318583 100
    del /q %temp%\list.txt
    ECHO Done

    Well Honestly that is not a concern for me maybe others

    I already know laptops lack performance vs the Desktop counter part

    Maybe ill give it a whirl but right now i see no need

    There is nothing really bogging me down maybe for future use Thanks !
