How to Undervolt Your Laptop


Your CPU is prone to heating if you carry out strenuous tasks on your computers like video editing or gaming etc. It can get even more troublesome if the thermal paste on the CPU is sapped or the ventilation is poor.

Overheating greatly undermines the performance of your computer, and you need to resolve the issue to improve your processor speed. One way around this dilemma is CPU undervolting, which can help you in reducing the power consumption and the temperature. Let’s understand the undervolting process and how you can go about it.

What is CPU undervolting

CPU undervolting refers to the process of reducing its operating voltage resulting in less power being supplied to the CPU, which will consequently cause the system to generate less heat.

It will thus reduce the heat of the CPU, control thermal throttling and increase the laptop battery life without any major risk involved. It will also not have any significant impact on the laptop’s performance.

Undervolting is a considerably safe process and can enable laptop users to use their devices for prolonged hours even if they want to carry out heavy activities like gaming.

How to undervolt your CPU

This article will guide you to undervolt your CPU through Throttle stop. You can download it here.

So, without any further ado, let’s get started.

Undervolting through Throttle stop

Throttle stop is used to override the throttling services to improve the CPU performance. Some of the features of this tool are listed below.

Speedshift: The speed shift feature in the Throttle Stop dashboard is applicable to modern CPUs and enables you to set your intel GPU or CPU to display the alterations made to the software-set clock speeds.

Speed Step: This feature is similar to Speedshift but is only applicable if you have an older CPU.

Disable turbo: The Disable turbo feature is intended to preserve battery life when you are using a normal program. It inhibits turbo boost and does not let the CPU core increase more than the base clock speed.

BD PROCHOT: Most laptops CPUs are designed to start throttling if the temperature reaches 100 degrees C. However, the CPU and GPU will start throttling with this feature if the laptop starts heating from the inside.

C1E: This feature helps conserve power, particularly in the instance of a low battery. The tool will automatically turn off the cores depending on the amount of work being done.

So, here is how the undervolting process can be done.

  • Download and open the Throttle Stop app. You can download it here. Use the latest version to ensure system stability. Before you undervolt your CPU, run a stress test to determine the base CPU temps.
  • Once you have determined the base temperatures, open the FIVR control panel in Throttle Stop and select the CPU core option to get to the CPU core voltage settings. You will see a checkbox with the label Unlock adjustable voltage. Select the Unlock adjustable voltage option and begin adjusting the offset voltage slider.

Use the settings as shown in the video:

 

  • Once done, close the FIVR control panel. Make sure to select “save volatages after throttlestop exits” – then run the stress test again to assess the impact of the undervolting process. If the laptop is working fine and doesn’t shut down at once, you can keep the new voltage settings
  • However, if your laptop shuts down after undervolting, restart your laptop and set a lower offset voltage value.

Remember, if you use Throttle Stop, you need to set it up so that it starts every time you reboot your laptop.
