What Is Overclocking?

Your computer’s central processing unit (CPU) has a maximum speed limit designed to operate. The manufacturer sets this limit, and it can’t be exceeded without an additional boost.

Overclocking is the process of pushing a CPU beyond its designed speed limits forcing it to perform more operations per second. It’s done by increasing the frequency, voltage, and other settings that allow it to operate faster than its original specifications. By doing so, you can get improved performance out of your processor and other components, such as memory and graphics cards.

How Does Overclocking Work?

Overclocking has become must easier nowadays with the help of extra utilities and automated tools. Generally, when overclocking your processor, you’ll need to set a higher frequency than its default settings, which is usually done within the BIOS or UEFI (Unified Extensible Firmware Interface).

By altering the settings of your computer’s BIOS (Basic Input/Output System), which acts as an interface between hardware and software, you can adjust the CPU’s clock speed. To overclock, you’ll need a compatible motherboard and CPU, as well as access to BIOS settings that allow for overclocking. You can also adjust the voltage your CPU receives so that it’s operating more efficiently at a higher speed.

Finally, you can adjust the multiplier and other settings to further enhance your system’s performance. This is all done by testing your CPU with benchmarking software such as AMD Ryzen Master or Intel XTU and tweaking settings until your desired results are achieved.

Why Consider Overclocking?

Overclocking offers a variety of incredible benefits in terms of performance. The most notable advantage is the improved speed and efficiency that comes with running your processor at a higher clock frequency. This can be particularly beneficial for gamers who need their hardware to perform optimally during intense gaming sessions.

Overclocking can be a great way to make your hardware last longer without the need for costly upgrades. You can squeeze out some extra performance by running your processor at its maximum potential before it needs replacing.

Can You Overclock Your CPU

Overclocking is surprisingly straightforward and easy to do. But it’s important to note that not all processors are capable of being overclocked. Processors that have been locked cannot be overclocked since they are programmed to run at a specific speed and cannot be changed to run faster.

Unlocked CPUs can be overclocked, which implies they can run faster than the speed for which they were built. You should check with the manufacturer before attempting any type of overclocking on your CPU.

Any Intel processor ending in “K,” such as i7-7700k, is capable of overclocking. Motherboards have a few more layers of complexity. You should choose a motherboard with a “Z” in the chipset name for Intel CPUs, such as the Z170 and Z270 motherboards. In contrast, overclockers have more freedom with AMD processors and motherboards because more of them are unlocked.

In addition to hardware compatibility, the cooling solution is an essential element that should not be overlooked. If you’re overclocking, it’s best to invest in a good quality cooling system that can keep your processor temperature under control, as overclocking can cause a lot of heating.

If in case you have a compatible processor and motherboard, as well as appropriate cooling solutions such as liquid or air coolers, overclocking is relatively easy. All you need to do is enter the BIOS or UEFI and adjust the settings accordingly.

You can also use automated tools such as AMD Overdrive or Intel Extreme Tuning Utility (XTU), which will help you take your system performance to the next level.

Note: It's important to bear in mind that overclocking is only meant for desktop computers and not laptops. Overclocking a laptop isn't as easy as with a desktop since the components are soldered directly onto the motherboard making them difficult to replace or upgrade.

Reasons to Avoid Overclock

Every silver lining has its dark cloud, and so does Overclocking. Overclocking can be extremely dangerous to your hardware if done incorrectly. A few risks to consider are:

  • Warranties – Most CPUs and some motherboards come with warranties that are rendered null and void if certain conditions are not met, and overclocking is one of them.
  • Temperature Sensitiveness – Your system’s heat sensitivity will be drastically changed by overclocking. As the seasons change, you may have to reduce your speeds to keep it stable with considerable temperature changes.
  • Efficiency – Although you can boost your CPU speed through overclocking, this doesn’t necessarily improve its data processing proficiency.

Safety Precautions for Overclocking

Overclocking is not without risk and can result in damage to your hardware if not done properly. It’s important to know the limitations of your hardware before attempting to overclock, as pushing it too far can cause serious and irreversible damage. Some safety precautions to keep in mind are:

  • It’s recommended to test your system stability before beginning the overclocking process, as this will help you identify any potential problems that could arise from increasing the clock speed.
  • Check the speed at which your motherboard chipset communicates with the CPU (also referred to as FSB). It plays a crucial part in determining the CPU’s general speed, measured in megahertz (MHz).
  • Identify the exact voltage of your CPU, as each processor has its own distinct voltage requirements.
  • Finally, always be mindful of the temperature and make sure you have appropriate cooling solutions in place, as overclocking generates a lot of heat which can cause serious damage if not managed properly.


Overclocking is an excellent way to get more performance out of your system, but it’s important to understand the risks and take proper precautions. You should research the compatibility of your hardware and software to ensure it is capable of being overclocked. Additionally, you need to factor in the cost of a compatible cooling system as well as the risk of voiding your warranty. If done properly, it can be a great way to get more performance from your existing hardware without having to purchase new components. As always, you should use your best judgment when attempting any type of overclocking.

Is Overclocking Safe?

Overclocking can be safe if done properly and with the right equipment, such as a good quality cooling system. It’s important to research the compatibility of your hardware and software before attempting to overclock. Additionally, you should factor in the risk of voiding your warranty.

What are the benefits of Overclocking?

Overclocking can provide significant performance boosts, allowing you to run more demanding applications and games with ease. Additionally, it can allow you to get more out of your existing hardware without having to buy new components.

Is Overclocking reversible?

Yes, most overclocking processes can be reversed by changing the settings in your BIOS. It’s important to take note of your original settings before attempting any overclock so you can return to them if desired.
