How to Undervolt Laptop to Increase Performance? – Guide [2021]

You might have noticed that while you are doing any sort of intensive computing tasks, your laptop undergoes a performance drop quite significantly. That’s where you need to learn how to undervolt a laptop, in order to enhance your laptop’s performance.

Now, this may sound like a daunting task to undervolt your laptop, but the risk of getting any problems is fairly low. In fact, the worst it could get is that the screen might lock up or a blue screen of death shows up. And none of them is a real issue!

So either it is to learn how to undervolt laptop-dedicated graphics, or how to undervolt GTX 1070 laptop, we have got your back! Down below is a detailed guide in this regard.

So without any further ado, let’s get right into it:

A Step-by-Step Guide on How to Undervolt Laptop

Undervolting your computer requires a few basic steps to be followed in order to improve the performance and battery life of your laptop. Down below is the series of steps that would help you through the process of reducing voltage supply to your laptop.

Prior to that, it’s important to choose which program you use to do the job. So here you have two options: either use Intel’s XTU program, only if you have a compatible processor or go for Throttlestop.

With that being said, we’ll start off by explaining the process via the Intel XTU program and then move on to the Throttlestop working procedure. Make sure to check them out so that you can get a better overview of both processes.

So, without further delay, let’s get straight to it:

How to Undervolt Laptop Intel?

That’s the easiest and convenient program to use in order to undervolt an Intel laptop. It takes no complex procedure to follow like that in the case of the upcoming Throttlestop tool. So on that note, let’s figure it out:

  1. First and foremost thing, you have to download the Extreme Tuning Utility (XTU) on your laptop, if you are not having it already.
  2. Then open the window, and tap on the Stress Test option on the left. Set the time for 30 minutes or so, to run a successful voltage test. This will help you determine a baseline for undervolting as it’d be the standard voltage supply of your laptop.
  3. After the Stress Test completes, get ready to undervolt your laptop! Simply go to the Core tab on the right. Select the Core Voltage Offset in the new window and set a new undervolt. Start by selecting the small undervolt and then move on to higher, until your laptop crashes or locks up.
  4. If so happens, then simply turn it back on, open the program, and select the one where undervolt was stable.
  5. Lastly, run a Stress Test again to make sure that your undervolt is stable for the long term.

And you’re done!

How to Undervolt Laptop Throttlestop?

Now it’s time to learn how to undervolt laptop CPU or the graphics processor by using Throttlestop. It is much similar to the previous one but somehow manages to be a little complicated.

That said, let’s get down to it:

  1. First things first, you have to download the tool. As the name suggests, it is used to put a stop to the laptop’s throttling; that is the lag in performance.
  2. Right after doing that, run the Stress Test to determine baseline voltage, clock speed, and temperatures.
  3. That done, click the FIVR tab and make some pre-modifications there. For instance, unlock the Adjustable Voltage, alter the offset voltage a bit, and then tap on the CPU Cache button to repeat the same settings in that as well.
  4. Press OK. Done that? Great! Now again run a Stress Test for half an hour. Then simply check on the most stable voltage supply to your laptop dropping from the baseline voltage. And the rest goes the same!
  5. Now the tricky part here with this tool is that you have to choose the right offset voltage, or default voltage setting, etc. So make sure you get through it easily and without facing any major setbacks while undervolting.

And that’s pretty much the end of how to automatically undervolt a laptop via Throttlestop.

Frequently Asked Questions

1. Is undervolting laptop safe?

Undervolting your laptop is a good option to increase better performance. However, if you do it overly, meaning if you undervolt your laptop or processor too far, then there might be a risk of losing stability. So much so, that it may lead to power-locking or may require rebooting.

2. How do I Undervolt my laptop?

The easiest way to undervolt your laptop is by reducing the voltage supplied to your CPU, without making any significant changes in CPU performance.

Simply put, you won’t be decreasing or increasing the clock speed, rather lowering the voltage supply directly; which means that you are giving less power to your CPU to meet the same level of performance as it was before.

3. Why can’t I Undervolt my laptop?

The most common of the reasons that you are unable to undervolt your laptop is that either you haven’t reset your computer’s settings to BIOS defaults, or you have left the BIOS-update settings turned on.

These two majors can become a hurdle while undervolting your laptop. Get that checked once, and then restart your computer. The undervolting settings will be available then.

4. Is undervolting GPU bad?

Undervolting your processors, either CPU or GPU can be a good option to get them better at performance. However, if you do it excessively, or go over a particular limit, especially in the case of GPU, then there’s a chance of getting the hardware damaged.

But the risk of getting the hardware damage is fairly low. Nevertheless, the most you can get as a negative of undervolting a GPU is instability.

Final Words:

So this was all about the basics of how to undervolt a laptop. There’s much more to it but the major part of its procedure has been discussed. Make sure to check this out before getting started to undervolt your laptop for better performance.
