Disable CPU Core Parking For Multi-Core Processors
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.
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 might 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.
