Do you want to boost your computer’s performance; by overclocking your CPU without BIOS through XTU but don’t know how to do it? If yes, then you are at the right place.

A slow CPU is one of the biggest hurdles in gaming, and everyone wants to find a way to speed it up and increase the performance of the processor and graphics card. Well, that is where overclocking can help. Want to know how? Then read the article till the end and learn to overclock your CPU effortlessly. So, let’s get started!

What Does Overclocking Do? 

Well, overclocking is the increase of multipliers on your CPU. It also increases a component’s clock rate; thus, it can perform various actions per second. During overclocking, you’ll be using the motherboard’s settings to increase the CPU’s speed from what it’s capable of by default. 

For instance, your CPU is running at 4GHz, but after overclocking, its speed will increase to 4.7GHz. It is a significant difference that can help improve your overall system and experience.

How to Overclock an Intel CPU with XTU (Without BIOS)?

Intel’s Extreme Tuning Utility (XTU) helps you overclock an Intel CPU without going into BIOS. This application is for hardware newbies as well as experts to overclock and monitor the Intel processor. Moreover, with XTU, you don’t have to run temperature or stress tests. XTU will do it all on its own.

Let’s walk you through the basic steps of overlooking your CPU by using XTU:

1. Set Up Baseline Performance

This step analyses your baseline score to compare it to the score you’ll get after overclocking. It’ll help you determine if the overclocking was effective or not. 

  • Search for Intel XTU and install it.
  • After installation, close background programs and start running XTU.
  • Locate the “Benchmarks” section and click “Run.” 
  • After around 2minutes, the overall stats of your processor will show up.

2. Eliminate Power Limits

You have to maximize three settings to ensure that your CPU extracts enough amount of power that it requires from your power supply.  You can avoid restraining your processor by going through the following steps:

  • Locate the “Advanced Tuning” window and click it to open.
  • In this window, you will be able to see and adjust all the CPU settings.
  • Now search for the “Turbo Boost Short Power Max” scrollbar and scroll it to the right.
  • Similarly, a “Turbo Boost Short Power Max” option can be enabled or disabled in some PCs instead of a scrollbar. You have to enable the option.
  • Now scroll the “Processor Current Limit” to the right as well. 

3. Expand Multipliers

Now the actual process will begin. Expanding the multipliers is the first step to increase your CPU’s speed. Follow the steps below to avoid any errors:

  • Set your “Reference Clock” to 1000MHz, which is the quantity of speed that’ll increase by increasing each multiplier.  
  • Go to the “Multipliers” setting. Here you’ll see each of your CPU cores. 
  • Increase the multiplier by one for each core.
  • After increasing the multipliers, go back to the “Benchmark” window and run it.
  • If everything is running smoothly, go to the “Profiles” section and save a new profile.
  • Repeat this whole process of increasing the multipliers, running the benchmark, and creating a new profile until your system crashes.
  • After your system crashes, reboot it and load the last saved profile.
  • Now move on to the next step to alter the voltage.

4. Increase The Voltage

You can increase the voltage in two ways. You can alter the voltage offset, which exerts more voltage when required. Alternatively, you can make a constant change in voltage by increasing the core voltage. Both can work, but it’s better to alter the voltage offset (to avoid access heating). However, here are the steps to increase core voltage:

  • Increase the core voltage by 0.1, and apply the settings from step 3. 
  • Now run the XTU benchmark to check if it crashes. If it doesn’t crash, it means that the increased power got stabilized. 
  • If it’s not stabilized, then keep repeating this whole process until the benchmark works. 
  • During this process, keep the CPU temperature in check. XTU shows the temperature on the screen, so you can keep checking constantly.
  • Try to keep the temperature under 80 degrees Celsius. 
  • When the temperature goes overboard, you should decrease the overclock by 150MHz.

5. Check Performance 

You can check the results by running a benchmark or by running some high-level application or game. If you see any difference in its performance, then congratulations! Your overclocking worked. However, if the performance remains the same, you can go through the preceding steps until you reach your desired results.

Alternatively, some sites compare your overclocking results to other people’s results who have the same hardware as you. The benefit of this is that you can estimate to what limit you can overclock your CPU safely. 

You can follow the steps below to compare your overclocking results:

  • After you’ve successfully overclocked your CPU. 
  • Upload your score to a pro overlocking site linked to XTU. 
  • Click on the high-scoring graph to get the settings of that to overclock. 
  • Apply similar settings into XTU for pushing your CPU to maximum speed.

Is It Safe To Overclock Your CPU?

Overclocking forces your processor to run at a faster rate than it’s supposed to. The more you force it to speed up, the more voltage you’ll have to provide it. Providing high voltages causes your PC to overheat eventually. You have to ensure that you maintain your PC’s temperature if you don’t want it to reboot completely.

Moreover, it is believed that increasing voltage and speed puts additional stress on the computer. Therefore, you are unknowingly cutting off your computer’s lifespan by 10years. For instance, your computer’s lifespan reduces from 20 to 10years. It doesn’t seem like that much of a big deal if you look at it like that.

However, if you plan to use the same computer for more than a decade, you should avoid overclocking.


To sum it up, overclocking is an excellent way of boosting your computer’s performance without paying for an expensive upgrade. It’s best to overclock your processor if you are a hardcore gamer to avoid any inconvenience while gaming. However, overclocking varies from system to system, and you’ll have to try overclocking more than once to get it right.

You might be avoiding overclocking because of the complications of getting into motherboard BIOS. However, this article will help you speed up your CPU by using XTU (it doesn’t require BIOS), especially if you are a beginner. We hope that you find this article helpful.
