How to Check If My CPU is Overclocked?

Overclocking a CPU can provide a noticeable performance boost for your computer, but it also comes with potential risks such as increased heat generation and reduced stability. If you suspect that your CPU may have been overclocked, there are several methods to check and confirm this. In this article, we will explore these methods and provide answers to some related FAQs.

**Method 1: Check BIOS Settings**

The most reliable way to determine if your CPU is overclocked is by checking the BIOS settings. Here’s how:

1. Restart your computer and enter the BIOS menu by pressing the designated key during the startup process. This key may vary depending on your motherboard manufacturer (common keys include F2, Del, or Esc).
2. Navigate through the BIOS menu using your keyboard and look for options related to CPU frequency, multiplier, or voltage. These settings control the CPU’s clock speed and can indicate whether it has been overclocked.
3. If the values in these settings are higher than the default specifications of your CPU, it is likely that your CPU has been overclocked. However, use caution when modifying BIOS settings to avoid causing any unintended issues.

**Method 2: Use Software Utilities**

If you are not comfortable accessing the BIOS or want a quick check, there are CPU diagnostic software tools available that can provide valuable insights. Some popular options include:

– CPU-Z: This popular utility displays detailed information about your CPU, including clock speed, multipliers, and voltage. Compare the displayed values with the manufacturer’s specifications to identify any discrepancies.
– HWMonitor: This versatile tool provides real-time monitoring of various hardware components, including CPU clock speed, temperature, and voltage. Look for unusually high clock speeds that could indicate overclocking.
– Intel Extreme Tuning Utility (XTU) or AMD Ryzen Master: These manufacturer-specific utilities offer in-depth control and monitoring of their respective CPUs. They can also help determine if your CPU is running at overclocked settings.


1. What are the potential risks of overclocking my CPU?

Overclocking increases power consumption and generates more heat, which can potentially damage the CPU if proper cooling is not in place. It may also lead to system instability, crashes, and a shorter lifespan for the hardware.

2. Will overclocking my CPU void the warranty?

Yes, most CPU manufacturers consider overclocking as a voiding factor for the warranty. It’s essential to understand the risks and consequences before attempting to overclock your CPU.

3. Can I revert the CPU overclocking settings to default?

Absolutely! You can reset the CPU overclocking settings to their default values by accessing the BIOS menu and choosing the “Restore Defaults” option. This will undo any modifications made to the CPU clock speed or voltage.

4. Are there any software tools specifically designed for GPU overclocking?

Yes, GPU overclocking utilities like MSI Afterburner, EVGA Precision X, and ASUS GPU Tweak are commonly used to overclock graphics cards.

5. Is there a recommended maximum temperature for a CPU when overclocked?

While it depends on the specific CPU model, it’s generally advised to keep the CPU temperature below 80-85 degrees Celsius when overclocked. Excessive heat can lead to thermal throttling and instability.

6. Should I overclock my CPU for gaming purposes?

Overclocking can provide a performance boost for gaming, resulting in higher frame rates and smoother gameplay. However, it is essential to understand the risks and ensure adequate cooling to avoid any potential damage.

7. Can I overclock a laptop’s CPU?

In most cases, overclocking a laptop’s CPU is not recommended. Laptops have limited cooling capabilities, which makes them more prone to overheating. Additionally, laptop manufacturers often lock BIOS options related to overclocking.

8. Will overclocking my CPU void the warranty of other computer components?

Overclocking the CPU should not directly void the warranty of other components. However, if any damage occurs as a result of overclocking, such as excessive heat damaging other parts, it may impact the warranty coverage.

9. Can I use the same methods to check if my CPU is overclocked on a Mac?

The methods mentioned above primarily apply to Windows-based systems. Checking for CPU overclocking on a Mac would involve using different software utilities designed for macOS, such as Intel® Power Gadget or iStat Menus.

10. Are there any signs that my CPU is being pushed too hard due to overclocking?

If your CPU is being pushed too hard due to overclocking, you may experience frequent system crashes, blue screens of death (BSOD), or sudden shutdowns during heavy workload or gaming sessions.

11. Can I simply increase the CPU’s clock speed without adjusting other settings?

While it is possible to increase the clock speed alone, it may not provide optimal performance gains. Adjusting other settings, such as the CPU voltage and multiplier, can help achieve better stability and efficiency when overclocking.

12. Should I consult a professional before attempting to overclock my CPU?

If you are new to overclocking or uncertain about the process, consulting a professional or experienced individual can be beneficial. They can guide you through the steps, help mitigate risks, and provide advice specific to your hardware configuration.
