3. Check Through BIOS

BIOS (Basic Input/Output System) is a type of firmware that stores information about the hardware components of a computer. You can check the BIOS settings of your computer to see if your CPU is overclockable. It will require you to enter the BIOS setup by pressing a specific key on your keyboard during the boot process.

Once in the BIOS, go to the “Advanced settings” and then to the CPU hertz part. Try to add digits beyond the available maximum hertz manually. If you can write the hertz, congratulations, your CPU supports overclocking.

4. Through Manufacturer’s Website

Lastly, visiting the manufacturer’s website is the most reliable way to check whether your CPU is overclockable. Here, you can find detailed information about the specs of your CPU and whether it is overclockable or not. But first, you have to check the details of your CPU. 

Task Manager is a reliable place to know CPU details. Press “Ctrl+Alt+Del” to open the task menu and select “Task Manager” from the list. Once in the Task Manager, go to the “Performances” tab and click “CPU” to expand CPU details. In the upper right corner, you can see which CPU you have.

Things You Need to Look For In An Overclocked CPU

There are several things you can look for whenever you are tracing an overclocked CPU. Before starting overclocking, you must check for the clock speed, cooling system, power supply, BIOS settings, and compatibility. It will reduce the risk of component damage.

1. Clock Speed 

The clock speed of an overclocked CPU is typically higher than the base clock speed, and it is important to ensure that the clock speed is within the safe limits of the specific CPU. You can find the safe limit of CPU clock speed on the manufacturer’s website. Many YouTube channels tell you how to safely overclock your CPU with a specific model.

2. Cooling System 

Because of the higher temperature it generates, an overclocked central processing unit (CPU) requires a more powerful cooling system than a regular CPU does. Check to see if the cooling system can handle the increased heat load and efficiently dissipate the heat it generates.

3. Power Supply 

To keep the system from becoming unstable, the power supply for a CPU that has been overclocked must deliver adequate power to the CPU and the other components. Before purchasing, verifying the power supply’s capacity and the power requirements of the central processing unit (CPU) is essential.

4. BIOS Settings 

It is essential to double-check that the BIOS settings have been set up appropriately for the overclocked CPU. It is essential that the configuration be tailored to the particular CPU in question and that it be capable of accommodating the higher clock speed.

5. Compatibility 

Check to see if the overclocked central processing unit is compatible with the other components of the system. Before making a purchase, it is essential to determine whether or not the central processing unit (CPU) is compatible with the motherboard, the RAM, and any other components. 

You can also determine compatibility from the manufacturer’s website. That information will be authentic and reliable to follow. So, always check your CPU details in Task Manager, search for the same model on the manufacturer’s website, or ask for online support.

Which CPUs Can Be Overclocked?

Only specific CPUs having specific frequency and voltage ranges can be overclocked. Overclocking is a process of increasing the speed of a CPU beyond the manufacturer’s recommended speed. It can be a great way to get more performance out of your computer without investing in a new processor. 

However, not all CPUs can be overclocked. Generally speaking, AMD and Intel CPUs can be overclocked. Most of the time, AMD CPUs are easier to overclock and have more room to go faster. Intel CPUs are more difficult to overclock but can yield decent performance gains. 

To determine if a specific CPU can be overclocked, check the manufacturer’s website or look for reviews or articles about the particular model. Generally, CPUs with an unlocked multiplier can be overclocked, while those with locked multipliers cannot. Additionally, higher-end CPUs may have a better potential for overclocking than lower-end models. 

When overclocking, it is important to keep in mind that the temperature of the CPU and other components can increase significantly. It is also important to note that overclocking may void the CPU’s warranty. As such, it is important to ensure that all components are properly cooled and that any modifications follow the manufacturer’s specifications.

How To Check If Your CPU Is Already Overclocked?

An overclocked CPU shows many signs, like overheating, increased clock speed, CPU voltage fluctuation, and high hertz in BIOS settings. These signs enable you to manage your CPU’s voltage, clock speed, and temperature, which protect your CPU from any component damage.

1. Check Your CPU’s Clock Speed 

The best methods to check it are to measure the voltage, the BIOS, and the CPU temperature. Clock speed measures the frequency at which a computer processor operates. It is measured in hertz (Hz) and is called the processor’s speed. 

The higher the clock speed, the faster the processor can complete instructions and tasks. Most CPUs come pre-overclocked from the manufacturer. To check the clock speed of your CPU, you can use a program like CPU-Z. It will tell you your current clock speed, and you can compare it to the standard clock speed of the processor.

2. Check Your CPU’s Voltage 

CPU voltage, or Vcore, is the amount of electrical power supplied to a central processing unit (CPU). The voltage ensures that the processor runs at the correct clock speed and performs properly. If the voltage is too low, the processor may not function properly and be damaged.

The voltage of your CPU can also indicate whether or not it has been overclocked. It is likely overclocked if the voltage exceeds your processor’s standard voltage.

3. Check Your BIOS Settings 

The Basic Input/Output System (BIOS) is software stored on a computer’s motherboard. During the boot-up process, the BIOS is responsible for setting up the computer’s hardware. 

Your BIOS settings will tell you if any overclocking has been done. Look for settings related to the processor’s clock speed or voltage and see if the values differ from the default. If the values exceed the default values, your CPU is already overclocked.

4. Check Your Temperatures 

As a processor’s clock rate increases, it typically generates more heat and is more sensitive to temperature changes. If the processor’s temperature rises above a certain threshold, it can cause the processor to become unstable and even possibly crash.

It can be prevented by providing adequate cooling to the processor, such as installing a high-end CPU cooler or water cooling system. Overclocking your CPU will usually result in higher temperatures than normal. If your CPU is running much hotter than usual and you can’t account for it, it may have been overclocked.


Overclocking is an effective way to get more performance out of your computer without investing in a new processor. However, not all CPUs can be overclocked, and not all can run at their maximum potential. 

To determine if a specific CPU can be overclocked, check the manufacturer’s website or look for reviews or articles about the particular model. It is also important to ensure the system’s components can handle the overclocked processor’s increased heat, power, and frequency. 

It is also important to ensure the BIOS settings are properly configured to accommodate the overclocked processor. Monitoring the CPU’s and other components’ temperatures is also important to ensure the system runs safely. Overclocking can be a great way to get more performance out of your computer, but it is important to understand the risks and take the necessary precautions.
