Is It Safe To Overclock CPU? – Save your pc

78 / 100

CPU overclocking is the process of increasing the clock speed along with performance. Though it’s not directly permitted by CPU manufacturers, it’s not illegal either. There is some confusion among PC users about overclocking the CPU. One of them is -“is it safe to overclock CPU of your computer?”. 

Well, overclocking is safe until you overclock it within the CPU capability limit. Once you exceed the limit, the temperature will be high. As a result, the CPU performance will be downgraded instead of increased. Even the increase in voltage can fry your CPU instantly. 

So, won’t you overclock the CPU? Obviously, you’ll overclock the CPU by increasing the multiplier and voltage gradually. But, keep your eyes open before the CPU temperature is too high. For the user’s convenience, the pros and cons of the CPU overclocking process are elaborated here. 

Benefits of overclocking CPU

Overclocking the CPU brings you some advantages to running your PC smoothly. Here you know about some of the key benefits. 

Increase in performance

What will happen if you overclock your CPU? Primarily, its performance gets increased during multitasking. Also, your gaming performance becomes incredible. Some graphics-intensive programs run more smoothly than old CPUs. Due to the increase in clock speed, the overall performance gets accelerated. 

Saves money

Overclocking means getting a kind of new CPU without making any purchase. If you purchase a medium-budget CPU and overclock it, then it’ll perform like a high-end CPU. Most importantly, the new CPU performance will be close enough to the high-end CPU. 

Experience full potential

Overclocking allows your CPU to run with the maximum clock speed. The fastest response time and the maximum graphics output can be received after overclocking. Without overclocking, you won’t get the full potential from other components. 

Device up-gradation

After overclocking, your hardware isn’t upgraded but the overall performance is. Your old device will perform like a new device due to a change in overclocking. There will be no lagging issue as well as hang issue. 

Helps to make a comparison

One of the top benefits of overclocking is performance comparison. Tech reviewers don’t need to purchase a high-end device to make a comparison with an old device. By recording the old CPU performance and overclocked CPU performance, they can easily distinguish between the performance.

Is It Safe To Overclock CPU? – More detailed information

So, is it safe to overclock the CPU of your computer? Overclocking the CPU isn’t risky unless you follow proper guidelines. Here you know about some risks of overclocking the CPU. 

Produce extreme heat

Overclocking is the process of increasing the multiplier on the CPU. This process allows your CPU to run faster. The clock speed and CPU voltage increase proportionally. And, heat also gets increased proportionally to the voltage. 

However, heat is the prime concern for CPUs. Extreme heat can lead to a shorter lifespan for the chip. If the CPU on load temperature is more than 86 degrees Celsius, it’s alarming for your CPU. This extreme heat won’t hamper your CPU certainly but will decrease the lifespan. 

High voltage production

Production of excessive heat doesn’t directly affect the CPU. But, high voltage is a great enemy for your CPU. High CPU voltage can even fry your CPU and damage it permanently. It’s recommended not to exceed a voltage of more than 1.25V. Though most motherboards can tolerate up to 1.4V, reaching the edge isn’t a wise move. 

Void official warranty

You must have received a warranty from the CPU manufacturer. Unfortunately, you will no longer be eligible for the warranty if you overclock the CPU. Overclocking the CPU means operating it at maximum clock speed. That sounds like a completely new CPU in performance. For this reason, you won’t get any service if it was included in your warranty condition.

Is it safe to overclock the CPU with a stock cooler? 

The answer is relative. Overclocking in any way is risky as it increases the temperature and produces heat. The stock cooler can run without throttling and remove excessive heat. So, most probably you’ll get proper support while overclocking. Remember, if you don’t have another backup cooler, then you may face difficulty. The situation may become worse as frying the CPU. 

How to safely overclock your CPU 

This is time to have a clear conception of how to safely overclock your CPU step by step. 

Step:1- Explore the BIOS

Start by restarting your PC and entering your BIOS. Look for an option called “Load Optimized Defaults”. You’ll find it near the “Save and Exit” feature. Go for the option to reset your BIOS. Besides, you need to turn off the “auto-overclocking” feature if your motherboard comes with it. 

Lastly, visit the Boot menu to ensure your PC is set to boot from the right hard drive. Reboot your computer to start the next step. 

Step:2- Run a stress test

A stress test helps you find out the chip condition precisely. Start OCCT and then you’ll find two windows. The left window will appear with the stress-testing options and the right one will show graphs. Tap on the right button now to understand the chip condition. 

Now, click the Green “ON” button. It’ll enable the stress test of the CPU. Monitor the temperature and run it for around 15 minutes. You shouldn’t see high values in the interval. When the time is over, reboot your computer.

Step:3- Start overclocking process

The process officially starts with increasing the CPU multiplier. You need to raise the multiplier slowly to make the process successful. Read the core ratio carefully and gradually increase the clock speed.  

Step:4- Again run the stress test

Before running the stress test, you need to set the voltage. Change the voltage changing option from auto to manual. Then, start a voltage near the CPU stock voltage. However, after a while, go back and run another stress test in OCCT. The process is already depicted in step:2. 

Step:5- Continuously increase the multiplier and voltage

Now all you need to do is increase the multiplier and voltage gradually. Reaching the endpoint, your CPU temperature will be extremely high. That’s where you stop the overclocking process. People make a mistake by running the process even after getting the extreme heat. As a result, all efforts get lost and the CPU becomes dead.

Frequently Asked Question

Let’s check some questions along with the answers related to CPU overclocking. 

Is it worth overclocking the CPU?

Obviously, the overall performance gets boosted by overclocking the CPU. By overclocking, you improve the clock speed of the chip. That’s why no lagging issue is found and your PC becomes fast enough. Overclocking doesn’t upgrade the hardware but boosts the CPU capability.

Do you still have any confusion? Watch the video below, it will help you for a better understanding:


So, you must have understood the steps of overclocking the CPU as it’s pretty simple. If you don’t run a stress test before starting the overclocking process, all your effort may get ruined. Besides, you need to boost up the multiplier and voltage by maintaining the correct ratio. 

Is it safe to overclock CPU of your computer? You have understood the possible risks of overclocking from this writing. The prime concerns of overclocking are heat and extreme voltage. Heat can reduce the CPU lifespan, but excessive voltage can ruin its whole life. 

However, we don’t discourage you from starting the overclocking process. After all, it provides you with an extra benefit of a performance boost. Also, overclocking is highly recommended for heavy users because they don’t need to spend even a single penny on this.
