Benefits and Drawbacks of Overclocking

Overclocking is increasing the clock speed of a computer’s processor or speeding up its memory, usually by jumping through extra steps that are added to the computer’s BIOS. Overclocking is generally done to get more performance from a computer by using more clock cycles. Still, other reasons exist, such as wanting to get rid of a noisy fan or perhaps improving system responsiveness. Another reason to overclock a system is to increase the amount of CPU time available for other tasks, such as playing games or running a virus scanner. Another reason may be because of a lack of support from the manufacturer. 

How overclocking is done?

  1. Overclocking can be done by several methods, including Using a software program to do the overclocking
  2. Using a hardware device to do the overclocking
  3. Overclocking BIOS by increasing the frequency of CPU (not recommended)
  4. Tweaking CPU frequency in Windows using Performance Monitor (30 or more steps) or other 3rd party software to monitor CPU frequency and change it based on a formula. This method is NOT recommended as it can cause irreparable damage to your motherboard and CPU.


1. Performance and lifespan. 

Overclocking increases CPU performance by increasing the operating frequency. The evidence is that many manufacturers offer a warranty on overclocked CPUs. The actual performance increase depends on many factors, including CPU architecture, software and hardware support, cooling system design, and motherboard quality. Overclocking can also harm lifespan because it increases stress on the CPU.

2. Cost Savings 

PC gaming can be an expensive hobby, but you can save yourself some money with a little bit of tweaking. One way to do that is by overclocking your hardware. Overclocking your CPU or graphics card can give you a performance boost for free. And if you’re worried about damaging your hardware, don’t be – most modern processors are designed to withstand small amounts of overclocking.

3. Maximized Speed 

Overclocking can help you reach higher speeds and provide a performance boost. It s not just the base clock of your CPU that matters; it is also what multiplier you choose to use. The higher the multiplier, the more power your CPU can use.

4. Device Upgrade 

Overclocking ensures that the obsolete equipment functions in more detail than the new ones would. The user of non-hardware components can ensure that the user still meets the existing demands through maximum clocking.

5. Test & Research 

Overclocking is sometimes used for testing and research purposes to see how effective it can be. This helps you get that extra performance at the expense of heat. It’s a good thing to keep in mind if you are going for overclocking, especially if you’re planning on making a custom build or need more OC headroom than what’s usually available.


1. Security risks. 

Overclocking can increase the processor’s operating speed above its maximum frequency. If this happens during a normal operation, it could cause damage.

2. Damage to motherboard and CPU. 

Overclocking can cause the motherboard and CPU to fail. This is one of the main reasons why overclocking is not recommended.

Not Recommended Most manufacturers do not recommend overclocking since it can give rise to serious risks, such as damage to the motherboard or CPU.

3. Heat and noise. 

Overclocking can increase the processor’s operating speed beyond its maximum frequency. This can cause a heat buildup in the case with the CPU and motherboard and significantly increase the noise level. Overclocking is not recommended for this reason.

4. power consumption and power efficiency. 

The higher the CPU operating frequency, the more power is used. An overclass CPU uses more power than its maximum frequency processor. Overclocking can result in high power consumption or even damage to the motherboard and system if not performed properly.

5. Warranty Nullify 

Most of the hardware warranties expire once you overclock them. This is because overclocking reduces the reliability of your hardware.

6. System instability 

Ensure you have a good cooling system, or your CPU will burn out when you overclock it.


Overall, overclocking offers some benefits but also has some drawbacks. Though the benefits of overclocking are good, it’s still better to avoid overclocking. Overclocking can be a very rewarding experience but should only be performed by experienced users who know what they’re doing. 

Frequently Asked Questions

What is overclocking?

Overclocking is the process of increasing a computer’s clock speed. When you overclock your system, the processor runs faster than its rated speed, which increases heat and power consumption. Overclocking can also cause instability and damage your system.

What are the drawbacks of overclocking?

Well, overclocking is hard to do properly. It would be best if you had a lot of experience and knowledge to overclock your system properly. Some drawbacks can be experienced when overclocking. Overclocking can cause instability and damage your system. However, this is a rare occurrence.

What are the risks of overclocking?

The most common problem when overclocking is overheating: The motherboard temperature rises to dangerous levels, and the computer becomes unstable.
Damage to the motherboard: Overclocking causes damage that a technician can’t repair.
Fire or explosion: Overclocking may cause an electrical fire in your computer. Ensure that you don’t overheat your computer when it’s turned on.
