How to Check if CPU is Overclocked [3 Easy Methods 2023]

Written By FarhanMax

Overclocking is a process that boosts a device’s clock rate and functions at a faster speed than it was initially meant to run.

However, many users are unaware that their CPU is in overclock mode or operating at a higher frequency than it was designed, in this article, I’ll show you three tried-and-true methods for determining if your CPU is overclocked or not.

Let’s get started.

How to Check if CPU is Overclocked

The Task Manager is the quickest way to see if your Processor is overclocking. Open Task Manager by pressing CTRL+ALT+DEL. Next, go to Performance and check if the clock frequency is more than the original. You can also use a tool like CPU-Z or GPU-Z to verify clock frequency.

Before you can determine whether your CPU is overclocked, you must first determine whether or not it is overclockable. Because only the K series CPUs for Intel processors are overclockable, the non-k version only runs its base and boosts speeds automatically.

On the other hand, you don’t have to worry about the AMD processors because every AMD CPU is overclockable out of the box. Overclocking a CPU is not always a safe idea because it can reduce the life of the CPU.

For example, an i5 12400 CPU indicates that it is an Intel non-k processor. Non-K series processors are locked. It can’t go above its boost frequency. According to the official Intel website, the highest boost frequency of the i5 12400 is 4.40 GHz. It can’t go above 4.40 GHz. intel-i5-12400

However, if you have an i5 12600k processor, it is a K series processor and can be overclocked. You may overclock this processor to its maximum frequency with a good cooling system.

Because overclocking your CPU generates heat, you must cool it before pushing it to a higher frequency. Overclocking also improves performance in games and other

If you have an Intel K series or AMD processor, the next section is for you; otherwise, you will be wasting your time and energy.

Here are a few methods to check if the CPU is overclocked:

1. Check Via Task Manager

From the Windows task manager, you can check your CPU frequency rate. The simplest way to see your processor clock speed is with the built-in Windows program.

Here’s how to check the CPU frequency rate in Task Manager:

  • Type Task manager in the Start menu to open it. task-manager-start-menu
  • Choose the Performance tab and click on CPU. performance-cpu
  • Check your CPU speed.

If you see your CPU speed exceeds the maximum turbo speed of your processor as specified by the manufacturer, your CPU is overclocked.

Note: Task Manager displays factual information regarding your Processor, so you may experiment with different workloads while monitoring the clock frequency.

2. Check Via BIOS

You may also check the frequency of your processor in BIOS. This process can be complicated, and you must not mess with the BIOS options.

The process for using the BIOS to verify CPU frequency is as follows:

  • Press Delete or the F2 key when the PC starts up.
  • Navigate to CPU settings.

Note: This setting name can be different for other BIOS systems.

  • Verify CPU Ratio, Adjust CPU Frequency, and Core Performance boost. cpu-settings-cpu-ratio-core-performance-boost

Note: if you see this value is more than the default value, then your CPU is overclocked.

By pressing the reset button, you can find your default value from those options. The reset button is beside the options button.

3. Check Via CPU-Z

CPU-Z is used to examine the frequency of your CPU. This free program displays precise information about your hardware, including the processor.

Here’s how to use CPU-Z to check CPU clock speed:

  • Download CPU-Z from their official website.
  • Install it on your computer following the on-screen instructions.
  • Open the software.
  • Select the CPU tab.cpu-core-speed

Examine the Clocks section on the CPU tab. If the processor’s Core Speed exceeds the CPU’s turbo frequency as specified by the manufacturer, it signifies that your CPU has been overclocked.

Why is My CPU Overclocked?

CPUs usually overclock themselves when users may unintentionally change a BIOS setting. Other reasons include the manufacturer overclocking the CPU from the factory, the user putting higher clock settings, and high voltage configurations in the BIOS manually.

Companies often overclock their CPUs before shipping them out. One of the most prominent examples is the Intel K series microprocessor. These K series processors are meant to be overclocked by the user, although makers provide additional performance boosts out of the box.

As a result, you may have bought a processor that the manufacturers have already overclocked.

Another explanation might be the user’s excessive core voltage adjustments. If your processor core receives extra power, it will attempt to run at a faster rate than usual.

So, even if you do not overclock your CPU, it will increase its core frequency when you increase its core voltage.

How to Stop Overclocking the CPU

To stop overclocking a processor, users must lower the core voltage, avoid changing CPU core settings without taking precautions, and disable Intel Turbo boost technology. Users can also reduce their processor clock frequency to stop the overclocking process.

The user can lower the processor’s core voltage, allowing the processor to run at peak performance while utilizing little power. This procedure prevents the CPU from overclocking and saves electricity.

Additionally, users can also disable the Intel turbo boost technology. This turbo boost technology allows the processor to run faster automatically. As a result, disabling the option prevents the processor from overclocking itself.

Finally, deactivating the overclock option in the BIOS prevents the processor from overclocking itself.

How to Check if GPU is Overclocked

The Task Manager is the quickest way to see if your GPU is overclocked. To find the GPU frequency, navigate to the GPU section under the performance tab. Users can also monitor their GPU clock frequency level using GPU-Z and the MSI afterburner software.

Determining whether or not your GPU is overclocked is straightforward. Just follow the methods below to check your GPU frequency.

Here’s how to see if your GPU is overclocked:

Examine Using Task Manager

The GPU-Z displays the GPU’s real-time frequency. So, before examining GPU frequency, you may need to place some workload on the GPU. It could be a game, a benchmark, or rendering.

The process for using the GPU-Z to verify GPU frequency is as follows:

  • Download and install GPU-Z from its official website.
  • Open GPU-Z and verify GPU Clock and Default Clock. gpu-z

If you notice that the GPU is running faster than the default clock frequency, this indicates that your GPU is overclocked.


Is it OK to not overclock?

In summary, overclocking isn’t necessary. However, if you’re using apps that benefit from it, it’s not necessary to pass up the extra speed.

Can overclocking cause permanent damage?

Overclocking is the primary cause of CPU overheating which lead to permanent damage. Excessive heat will force your Processor to malfunction and possibly cause great harm.

How much overclock is safe?

Anything less than a 10% overclock is safe and will still deliver consistent performance. If your machine breaks down or your games begin to misbehave, your hardware might not have the ability to overclock.


If a CPU overclocks itself without the user’s consent, it can harm the CPU and other hardware related to it.

To prevent this situation, I’ve demonstrated in this article how to determine whether the CPU is overclocked precisely.
