Modern computer processors (CPUs) are really very powerful as they are powered through a number of cores. Even though these multiple cores make the CPU attain a very high overall clock frequency, all these cores together consume a lot of power too. In addition, you have to deal with the heat generated by all of these cores put together. Windows tackles this problem by putting the unused cores in the standby or the parking mode, thereby saving the consumed power and reducing the generated heat. But Windows does not give you any control over how it determines about how many cores and when they are put in the parking mode.
This is where a new software called ParkControl can help you out. The developers of this software have determined that by choosing the power profile configuration carefully, you can actually manage how Windows controls the CPU core parking.
In the ParkControl application, it displays the current power profile in use. The parking AC and parking DC settings show how Windows parks the CPU cores in the AC and DC (battery) mode respectfully. The frequency scaling setting determines how Windows scales the CPU frequency to reduce the power consumption for AC and DC modes.
You can choose a power profile that you want to make changes to. Then you can choose the parking or frequency scaling percentage for that power profile. This percentage is the percentage of CPU cores that should be put in the parking mode if such a necessity arises. For example, if your CPU has 4 cores and this setting is 25%, then 25% of 4, or 1 core will be put in the parking when Windows decides to use the CPU core parking function.
Conclusion: ParkControl lets you configure how many CPU cores are put in the parking mode by Windows. It can help you find a suitable configuration for your PC to maximize the CPU performance and at the same time to save the power consumption by different cores of the processor.
