How To Underclock CPU [A Complete Guide To Downclocking Your CPU In 2021]

Do you want to know How To Underclock CPU? Read on.

A CPU or Central Processing Unit is the brain of your computer. It does all the calculations and processes data to provide you with a smooth experience whilst using it. Overclocking is where you alter the settings on your CPU so that it runs faster than its default settings.

Underclocking is when you change these settings so that they are lower than what they would be at their default speed. This can help save power and reduce heat output from your computer, but it can also have negative impacts on performance depending on what tasks are being carried out by the CPU at any given moment in time. 

Most people would agree that computers are not as fast as they used to be. There is a reason for this, and it’s because of the way our processors work. A processor can only run so many instructions per second before it overheats and shuts down.

This means that you need to limit how much power your computer is using to keep up with changes in technology over time. With some quick adjustments, you can help prolong the life of your CPU while still enjoying modern programs.

What Is Its Purpose? 

Underclocking is a common technique that many people use to help save money on their energy bills. The idea is that you can get the same performance from your system by running it at a lower voltage and frequency, which saves power and generates less heat.

Most of the time, this technique works well enough for most users, but there are some instances where it does not work: like if you’re doing CPU-intensive tasks like video editing or rendering 3D graphics.

Have you ever wondered why your computer is always running slowly?

You may have noticed that while browsing the web or working on a document, your CPU usage is at 99% and the fans are blowing full speed. What’s going on here?

The answer to this question lies in underclocking.

Underclocking is an energy conservation technique where the frequency of a processor core, bus, or voltage supply for microprocessors can be deliberately reduced below its rated nominal level.

The goal of underclocking is to reduce power consumption without reducing performance by lowering system voltage levels and slowing down clock speeds when no demanding tasks are being performed.

  • Is Underclocking Safe?

Is underclocking safe? The answer is yes, but it’s important to know the risks associated with this tactic. Underclocking your CPU will typically result in lower power consumption and can extend battery life on laptops and tablets.

It also allows you to downclock your GPU for improved performance or save money on electricity bills if you’re using an older computer that doesn’t need as much processing power.

There are however some risks to consider including reduced system stability, reduced speed of data access, and decreased lifespan of hardware components such as the hard drive.

  • How To Underclock your CPU With Windows?

This is a tutorial that will show you how to underclock your CPU with Windows.

This can be useful for many reasons, such as saving power or reducing heat in the case of an overclock gone wrong. Follow these steps and you will have successfully underclocked your CPU:

  • Go to Start Menu -> Control Panel
  • Double-click on the System icon
  • Click Advanced system settings on the left side menu bar
  • On the Advanced tab, click Settings… (under Performance section).
  • You are now on the Performance Options window.
  • Click on the Advanced tab at the top, then choose “Programming” under Processor performance options.
  • Now you will see a dropdown menu that reads “Maximum processor state”. Simply change it to 99% or 96%. This is what I recommend for not overheating your CPU when doing things like gaming.
  • Now you will see your new “Maximum processor state” setting in the main window. Click Apply, then OK to complete! You have now successfully underclocked your CPU with Windows.
