Modern CPUs are becoming immensely powerful. This is because they are powered by a number of cores. These multiple cores can definitely make the CPU reach a very high overall clock frequency, but all these cores together actually consume a lot of power. Windows has a solution to this problem. It tackles it by putting all the unused cores in the standby or parking mode so that power can be saved and there is less heat generation.
However, Windows does not let the users set the CPU frequency scaling. It also doesn’t allow any control over how many cores and when they are put in the parking mode. This is where ParkControl comes into action and can help you out. ParkControl is a free and portable tool which can be used to tweak core parking and CPU frequency scaling settings.
What is Core Parking and CPU Frequency Scaling
Core Parking is basically an attribute (setting) of Power Profiles. This CPU feature basically makes your processors go into a sleep mode which is known as (C6). This feature is supported by most of the new processors. Basically, Core Parking allows your computer to save power. Individual processor cores can be disabled with this feature when your system is idle, and further, it can be turned back on as the individual resumes work on the system.
CPU Frequency Scaling is a feature that enables the operating system to scale the CPU frequency up or down to save power. Depending on the system load the CPU frequencies can be scaled automatically, this is in response to the ACPI events. It can also be manually done by using some programs.
Control the CPU frequency scaling setting with ParkControl
To put it simply, this free application actually allows in adjusting the Core Parking of the CPU for one or more energy profiles on the machine. By portable, it means that tool does really need installation. This means to get started with this tool you just need to download and run an executable.
ParkControl, the free tool to control CPU frequency scaling setting and Core parking, is a lightweight tool; with the size of just 1.44 megabytes. The tool also doesn’t have an installer.
The interface of ParkControl is divided into two panels:
- CPU frequency scaling settings for power profile to the left: This part of the panel features a dropdown can be used to enable a power profile.
- Current system power status to the right: This part of the panel displays the CPU’s number of cores, frequency, and usage/parking status.
The tool also has options featured to enable parking AC, parking DC, frequency scaling AC, frequency scaling DC. The Dynamic Boost (auto-switch of power plans on idle/active) requires ParkControl Pro which is not free.
Control CPU core parking in Windows with ParkControl
With ParkControl an individual can easily choose the power profile configuration carefully, which helps to efficiently manage how Windows controls the CPU’s core parking.
How to use ParkControl
First of all, download and install ParkControl. Once the application is run, you will see that the interface of the tool is easy to understand.
ParkControl can be used to disable some of the unused cores on your system when it’s loading slowly. As we said by doing so, one can reduce the energy consumption and also heat dissipation from the system. Since Windows does not provide any direct way to adjust these parameters, ParkControl becomes a winner here.
ParkControl allows you to configure how many CPU cores are actually put in the parking mode by Windows. It can also help you find the most suitable configuration for your PC which will help you squeeze out the maximum from your CPU. There are many benefits to using this tool, enhanced CPU performance, save time and also save the power consumption by different cores of the processor.
You can download ParkControl from here. It is important that you know about the changes you make, and so it is not a tool for everyone to use. Read and learn about the changes you need to apply to your system and then apply them easily with the help of this tool.
