How to Underclock your GPU

Before we go to the actual process, let’s check whether or not you need an underclocked GPU

Would you ever consider underclocking your GPU? Well, many people will wonder why someone would want to underclock a GPU while most people are out there trying to overclock theirs? We’ll explain later; this article is for anyone who wants to know how to safely and reliably underclock a GPU.

Now, what are some of the common reasons why people decide to underclock their GPU’s?

Reasons why people underclock their GPU’s

Most people might be wondering, why would you want to underclock your GPU? Shouldn’t you be overclocking to increase the performance of your computer? I mean, underclocking should, in theory, reduce performance right?

Well, regarding gaming underclocking is a no-no unless you want to reduce your performance significantly. However, for day to day usage of your computer. Underclocking is a good thing as it reduces the usage of your electricity and saves you money. Because your GPU is not undergoing active usage, underclocking will not reduce your performance.

Other reasons why people may decide to underclock their GPU’s because of the temperature, in countries in the Mediterranean and many parts of America and Europe, summertime temperatures can be nearly 10 Celsius higher than temperatures during other seasons. Other reasons include that their GPU may be lagging slightly behind other components such as RAM but not enough to justify spending a lot of money to upgrade. (Make sure all your hardware is compatible though)

The increased temperature reduces the temperature gradients that GPU’s use between colder air and the hot GPU to cool themselves, hence making it harder to keep your GPU cool. People may also have defective thermal paste or may have defective cooling units among other reasons to underclock.

To summarize the various benefits that underclocking GPU’s have:

  • Lower chances of overheating

With an underclocked GPU, the chances of your GPU overheating become lower as a result of the reduced usage of your hardware. The reduced use makes it harder for your GPU to heat up.

  • Cooler GPU

Because an underclocked GPU doesn’t use as much power to run, your GPU will likely run at a much lower temperature than running it at normal clock speed.

  • Less Power usage

Reducing clock speeds reduces usage of power because the hardware just isn’t running at the capacity that it usually does.

Lower power usage means that you will save a lot of money on power usage.

  • Quieter

Fans have to run faster the higher the temperature of a piece of hardware gets, to run faster the fan makes a lot more noise.

If you believe that underclocking your GPU is the best solution, continue below to see the steps to underclocking your GPU.

Next, install MSI Afterburner.


After installing MSI Afterburner, open it up.


Now, underclock your GPU by whatever frequency is desired and click the checkmark to apply.


And you are done!

Does Undervolting Do The Same As Underclocking?

No, undervolting doesn’t equal underclocking.

Undervolting is the process of reducing the voltage of a specific computer chip; this can be done mostly via the same tools as underclocking.

Underclocking is the process of reducing the speed at which specific computer chip runs (it’s core clock).

For the most part, we don’t recommend undervolting as it can lead to instability in a computer part. Unless you know what you are doing, we advise against undervolting.

Can I reduce anything else?

Yes, you can reduce things like fan speed and memory speed if you wish to reduce power consumption even more.


Underclocking your GPU is not a thing that most people do, for most gamers underclocking your GPU is contrary to what your objectives usually are. The specific scenarios to which underclocking will help you often don’t usually occur to most people who enjoy this website, but some people will be assisted by it.

The usual scenarios where underclocking gives a benefit is if you aren’t using most of your GPU to play games all the time. In this case, having a GPU run at full capacity can be quite costly over time due to electricity bills.

If you fit this scenario, underclocking your GPU can reduce your power usage while also keeping the majority of your performance in non-gaming tasks.
