How to Underclock your CPU – A Complete Guide to Downclocking your CPU

How to underclock your CPU

Underclocking or downclocking is the alteration of a computer’s settings to make it run at a lower clock rate than its default. Underclocking is usually done at the factory level but can also be done by the end user. 

How to Underclock your CPU

Some laptops and systems these days have the automatic underclocking feature, which detects if the system needs underclocking and reduces its clock rate automatically without the need for manual tampering.

What is its Purpose? 

You might have noticed that on many occasions, the computer heats up and, in the case of laptops, also drains the battery pretty quickly. Underclocking is done with the purpose of reducing the power consumption of the computer, reducing its heat emissions, and increasing its battery life. It is also known to increase the lifespan of the hardware and reduce noise from mechanical parts.

In many cases, underclocking, when done properly, also improves the stability and compatibility of the system.

Is Underclocking Safe?

Yes, it is safe. While Overclocking is dangerous if overdone or done incorrectly, underclocking is safe and easy to reverse. The system will revert to default settings if it senses the need for it, while you can also do this manually. Like we mentioned above, underclocking helps in terms of heat emissions, battery life, and power consumption. This comes at the cost of a slight dip in system performance. 

How to Underclock your CPU with Windows

How to Underclock your CPU with Windows

There are two methods to underclock the CPU with Windows. You can underclock the processor by either lowering the Thermal Design Point (TDP) through the Intel Thermal Framework settings or through the Processor Power Management. 

Let us have a look at the first method:

  1. Right click the Start button and go to Settings.
  2. In the Settings page, click on System and then go to ‘Power & Sleep’.
  3. Go to the ‘Related Settings’ section and click on ‘Additional Power Settings’.
  4. Click ‘Change Plan Settings’
  5. Click ‘Change advanced power settings’
  6. Click the expand button beside Intel® Dynamic Platform and Thermal Framework Settings.
  7. Click the expand button beside ‘Config TDP Level’ and then click on ‘Battery’.
  8. Now select ‘Low TDP’ from the dropdown option next to ‘High TDP’.
  9. Click Apply, followed by OK.

The second method is particularly useful when you cannot see the Intel® Dynamic Platform option in your system.

  1. Right click the Start button and go to Settings.
  2. In the Settings page, click on System and then go to ‘Power & Sleep’.
  3. Go to the ‘Related Settings’ section and click on ‘Additional Power Settings’.
  4. Click ‘Change Plan Settings’
  5. Click ‘Change advanced power settings’
  6. Click the expand button next to Processor Power Management.
  7. Click the expand button next to Maximum Processor state.
  8. Click on Battery.
  9. Alter the percentage level to which you’d like the processor to operate at.
  10. Click Apply.

Underclocking CPU from the BIOS settingsUnderclocking CPU from the BIOS settings

BIOS is the abbreviation for ‘Basic Input Output System’. You can underclock the processor from the BIOS settings page. This process is more complex, and many users have reported that it hasn’t worked for them. But you never know! It may end up being the best solution for you. We say there’s no harm in trying it, especially if nothing else is working.

Here are the steps:

  1. Open the BIOS settings page. This step will depend on the brand of computer and may need you to press a key or combination of keys during the boot process. Check how to reach the BIOS settings page for your computer and access to get started.
  2. Find the Frequency / Voltage Control settings. The BIOS Settings have many options of settings, each for different parts of the computer. Navigate to locate Frequency / Voltage control.
  3. Go to – Advanced Frequency Settings. And the Advanced CPU Core Features
  4. Decrease the CPU Clock Speed. 
  5. Decrease the Core Voltage.
  6. Save and Exit.
