Overclocking is one way to make your processor run faster without having to change it. Most people accomplish this with BIOS, but without BIOS, overclocking is still possible. Whether you are a beginner or a pro, Intel’s Extreme Tuning Utility called XTU for short, can help you easily overclock CPU without BIOS.
While overclocking, there is a high tendency for your device to run really hot. Also note that overclocking your CPU could mean speedier wear and tear for it. The XTU though, comes with built-in CPU and memory testing to check the temperature and stability of your device. Many opt for overclocking CPU without BIOS because the other option of overclocking with BIOS can be pretty cumbersome.
Note that the XTU is specially designed for Intel processors which is what this article is focused on. For AMD processors, the XTU’s equivalent is the Ryzen Master. It is also noteworthy that if you successfully overclock CPU without BIOS, the difference from its previous status might not be significant in numbers but will be in performance. Now let’s look at how you can overclock CPU without BIOS.
How to Overclock CPU without Bios: The Processes
1. Download Intel XTU
The first step to take is to download and install Intel XTU from Intel’s site. Next, close all background apps and launch the software.
2. Run Benchmark
This is to test your PC and get your current benchmark score. Click on Basic Tuning and you will see where to click on Run Benchmark. Wait till it’s done. You will see some stats and get your benchmark score. After overclocking, this score should be a bit higher, so you’ll know if your overclocking worked or not.
3. Go to Advance Tuning
Click on the Advanced Tuning tab to tweak your CPU settings before overclocking CPU. From there, you can remove power limits so that your CPU can get the maximum amount of power needed.
Locate the Turbo Power Boost Max and slide it all the way to the right, to the highest limit. If the displayed page shows a Turbo Boost Short Power Max option, enable it. Also slide the Processor Current Limit option all the way up. Now, you can easily move to the next step, which is to overclock system.
4. Overclock System
You can do this by sliding the Processor Core Ratio and Processor Cache Ratio to maximum, that is, all the way to the right and Click Apply. Then go under Witness Performance Improvement and Run Benchmark. It will give a new score after a while. Compare it to the first benchmark score you got to see if there was any increase. You can also try the following instead of setting to maximum directly.
5. Increase Multipliers
This is where you get to push your CPU past its current speed. Set Reference Clock to 100MHz. Go to Multipliers setting which shows each CPU core and increase the multiplier by 1x for each core, then Run Benchmark. Wait to see if your system crashes, if it doesn’t, go to the Profiles tab and save this new profile.
Try to increase the core again by 1x and see if the system crashes. Keep doing this until the system crashes. Make sure that after increasing the multipliers each time, you save a new profile. This way, when the system crashes, you can reboot and use the last saved profile which didn’t crash your system.

6. Increase Voltage
Increasing Multipliers and Voltage is equivalent to overclocking your CPU. All you have to do here is increase the voltage offset which applies more voltage only when needed. The other option is to alter the core voltage, but this will keep your system perpetually running on this voltage which translates to more heat. The former is the better option.
If though, you choose to change voltage core, just keep increasing the core voltage by 0.1 and run benchmark each time to be sure that the added power has worked to stabilize things. Read also: How to Increase FPS on Windows 10 Laptops
