ParkControlFree: Modify the power profile of your computer


Park Control is a small free application that allows you to customize your processor parking core for one or more energy profiles in your machine. You can use this application to turn off some of your unused kernels on your computer, thereby reducing energy consumption and heat dissipation. By default, Windows does not provide an immediate way to customize these parameters, which makes this application particularly interesting.

On the contrary, it can be used to disable kernel parking and allow the processor to not reduce its operating frequency, thereby increasing their performance. Before proceeding to the analysis of our article, it is worth noting that the application on the one hand does not require installation on the other hand consumes minimal resources and does not affect the overall performance of the computer.

Let's get to the implementation now. As you can see the menu includes the available kernels of our processor and the settings we can apply.

Starting from left to right we see in the first tab the option AC Parking (we use this option when our computer is plugged in). With the available settings we can either increase the kernels that are on hold until our load exceeds a certain value or turn it off completely so that all kernels operate independently of our processor load.

In the next tab we see the Parking DC option which does exactly the same thing with the exception that it is activated when the computer is plugged in and running on battery power.

Now let's get to CPU frequency scaling. (Dynamic Frequency Scaling (also known as CPU throttling) is a technique in computer architecture, where the frequency of a microprocessor can be automatically adjusted to the actual needs, to save energy and reduce the amount of heat generated by the chip. Dynamic frequency scaling helps maintain battery life in mobile devices and reduces cooling and noise costs.)

In the next tab we see the option Freg Scalling AC. By default, the processing frequency of our computer fluctuates for the reasons we explained above depending on the CPU load. (we use this option when our computer is plugged in).

We are now coming to the latest Freg Scalling DC option which is exactly the same setting which will be activated when our computer is running on battery only. The tests found that AMD processors benefit more from disabling kernel parking. This is perhaps due to the dramatic difference in the way AMD processors share computing resources between logic cores.
