Is Your CPU Overclockable? (How to check if CPU is overclocked)

When it comes to improving your PC’s performance, one of the most popular options is to overclock your CPU. Overclocking is a process that involves manipulating system settings to increase the processor’s clock speed beyond its specified limits.

This can allow you to get more out of your hardware and take advantage of higher performance capabilities without having to upgrade any components. But before you attempt overclocking, it’s important to determine whether or not your CPU is actually overclockable in the first place.

Since processors are designed with certain limitations and specifications, not all CPUs are capable of being overclocked safely. Depending on what type of processor you have and its cooling capacities, overclocking can cause overheating and other detrimental effects if done improperly.

It’s also worth noting that some manufacturers will void the warranty if they detect an attempt to overclock, so it pays to do research first. So, In this article, I will explain how to check whether or not your CPU is overclockable.

Do you need to overclock your CPU?

Normally, if a user wishes to increase the overall performance of their computer, overclocking may be an option worth considering.

However, this should only be done when absolutely necessary; there are a number of potential drawbacks and risks associated with overclocking that should not be overlooked.

For starters, it is important to note that overclocking your CPU can void the manufacturer’s warranty on the processor or the entire system depending on the device.

This means that any repairs or replacements required as a result of overclocking would have to be paid for out of pocket.

There is always the possibility that an aggressive overclock could cause permanent damage to either the processor itself or other components within the system such as its power supply.

It is also important to understand that in order for an overclock to be successful, more than just software adjustments need to be made; additional cooling usually needs to be added in order for the processor to remain stable under higher clock speeds and voltages.

This means investing in an aftermarket cooling solution like water cooling or even investing in a case that allows for improved airflow.

Not taking these steps can lead to overheating and instability issues which may not only reduce performance but also potentially damage expensive components.

How do I know if my CPU is overclockable?

For those looking to get more performance out of their computer, overclocking is a great way to do it. But before you start tweaking your processor, how do you know if it is even overclockable in the first place? To properly determine if your CPU is overclockable, I’ve listed several steps you can take.

Check Your Manufacturer’s Website

One of the easiest ways to find out if your CPU is overclockable is to simply check the manufacturer’s website.

Most major CPU manufacturers have pages dedicated to each model that lists all of its features and specifications, including whether or not it can be overclocked.

If you don’t see anything about overclocking on the page, then chances are that your particular CPU isn’t designed for it. 

Take a Look at Your Cooling System

If your processor has an air cooler attached to it, then it may be possible for you to overclock.

Air-cooled systems are typically designed with overclocking in mind and most CPUs with air coolers will support some level of overclocking.

However, if you have a liquid cooler installed on your system then chances are that your processor won’t be able to handle any additional voltage or heat generated by higher clock speeds.

Use Benchmarking Software

Benchmarking utilities like Cinebench R20 can help identify potential problems with an overclock before they become an issue by running stress tests on different components within a system such as memory speed, processor speed, etc.

These tests will allow you to push each component up until a certain point where stability becomes compromised so that you can gauge exactly how far you can push your particular hardware without causing any permanent damage or instability issues with other components in the system.

Consult A Professional

If all else fails, consider consulting a professional who specializes in customizing PCs for gaming and other intensive tasks like 3D rendering and video editing they may be able to provide insight into whether or not your particular processor would benefit from an overclock based on their experience with similar hardware setups and performance gains achieved through additional tuning techniques like memory timings adjustments and BIOS updates/flashing.

The Popular Methods to Check CPU Overclocking

Checking through Task Manager in Windows

let’s move on to how we can check if our CPU is overclockable using Task Manager in Windows.

  • To start with, open up your Task Manager by pressing CTRL + ALT + DEL simultaneously on your keyboard.
  • Then click on the “Performance” tab at the top of the window and then take a look at the “Processor Frequency (GHz)” section underneath that tab; here you will see whether or not your processor supports overclocking as indicated by either 0 or 1 GHz being listed after the words ‘Overclocked.’
  • If 0 GHz appears after ‘Overclocked,’ then unfortunately your processor does not support overclocking; however, if 1 GHz appears then congratulations –your processor supports overclocking.

Checking through CPU-Z

CPU-Z is a free utility for Windows that provides detailed information about your system’s hardware, including your processor, memory, motherboard, graphics cards, and more. It also allows you to check the status of your system’s components in real-time. One of its most useful features is the ability to detect whether or not your CPU is overclockable.

  • Once you install and launch the program, it will automatically detect and display information about your system’s hardware in real-time.
  • You can then click on the “CPU” tab at the top of the window to bring up more detailed information about your processor.
  • On this page, you will see several tabs including “Core Speed” and “Voltage/Frequency Curve” which can help you determine whether or not your processor is overclockable.

The Core Speed tab shows you the current clock speed of each core in your processor as well as its maximum frequency (the highest frequency it can reach).

If this maximum frequency is higher than what was specified by Intel or AMD for that particular processor model then it means that it has been overclocked by someone else which indicates that it has some degree of overclocking potential.

Additionally, if there are voltage/frequency curves displayed in the Voltage/Frequency Curve tab then this also means that there is some degree of overclocking potential present in this CPU. 

Checking through the BIOS

To determine if your CPU can be overclocked via the BIOS, you should start by accessing the BIOS menu.

  • This can be achieved by pressing a designated key or key combination when you encounter the prompt during the initial boot process (commonly “F2” or “Delete”).
  • Once inside, look for an option called “CPU Frequency/Voltage Control,” which should be in either Advanced Settings or Performance Settings depending on your motherboard manufacturer.
  • This menu should contain options such as “FSB Frequency Control” and “Voltage Control” which will tell you whether or not your CPU is overclockable. If these options are present, then you should be able to adjust them and overclock your CPU with relative ease.

If these options are not present, then unfortunately your processor cannot be overclocked and any attempts at doing so could result in damage to both hardware and software. 

Which CPUs can be overclocked?

The following list contains all Intel and AMD processors that have been certified for overclocking by their respective manufacturers: 

Intel Processors: Core i7-8700K, Core i7-8700, Core i5-8600K, Core i5-8400, Core i3-8350K, Core i3-8100, Pentium G4620, Pentium G4560, Pentium G4600, Pentium G4520.

AMD Processors: Ryzen 7 1800X, Ryzen 7 1700X, Ryzen 5 1600X, Ryzen 5 1500X, Ryzen 3 1300X.

It should be noted that these are only the latest processors available on the market today; many older models also support overclocking but they may require additional steps (such as BIOS updates) in order to do so.

It is also important to remember that even if a processor supports overclocking doesn’t necessarily mean it will work well when pushed beyond its normal limits.

Some chips may show improved performance while others may suffer from instability or other problems due to being pushed too hard.


When researching the capabilities of your CPU, finding out whether or not it is overclockable is an important factor to consider.

Overclocking can give more speed and power to your processor but can come with risks if not done correctly making sure you have the right cooling and knowledge beforehand is essential.

While it might seem daunting at first, many modern motherboards today allow for easy overclocking so those who want to get the most out of their PC should definitely check out their XMP profile for the maximum potential their device can offer.

After all, I also explain some popular methods to check if your CPU is overclocked and how to do the overclocking process itself.

Now that you have a better understanding of what overclocking is and how it works, you should be able to make an informed decision on whether it is right for your setup.
