How to Know if CPU Is Overclocked

Overclocking a CPU can be an effective way to boost your computer’s performance, but it also comes with potential risks. If done incorrectly, it can lead to instability, overheating, and even permanent damage to your processor. Therefore, it is important to know if your CPU is overclocked or not. Here are a few ways to determine if your CPU is running at overclocked speeds:

1. Check BIOS Settings: Restart your computer and enter the BIOS settings by pressing the designated key (usually Del or F2) during the boot process. Look for any indications of overclocking, such as increased CPU frequency or voltage settings.

2. Use CPU Monitoring Software: Install monitoring software like CPU-Z or HWMonitor that provides real-time information about your CPU’s clock speed, voltage, and temperature. If the clock speed is higher than the advertised speed, your CPU may be overclocked.

3. Monitor CPU Temperature: Overclocking tends to generate more heat, so monitoring your CPU temperature can give you a clue. If your CPU is consistently running hotter than expected, it might be overclocked.

4. Observe System Stability: Overclocking can make your system unstable. Frequent crashes, blue screens, or random reboots can indicate that your CPU is running beyond its capabilities.

5. Compare Benchmark Scores: Run benchmark tests like Cinebench or Geekbench to compare your CPU’s performance with similar systems. If your scores are significantly higher than expected, it might be due to overclocking.

6. Check for Modified Hardware: If you purchased your computer or CPU from a third party, it is possible that they have already overclocked it. Look for any signs of modified hardware, such as aftermarket coolers or liquid cooling systems.

7. Consult Manufacturer Specifications: Lastly, refer to the official specifications provided by the CPU manufacturer. Compare the advertised clock speed with the readings you obtained from monitoring software.


1. Is overclocking safe? Overclocking done within safe limits is generally safe, but it can void your warranty and increase the risk of hardware failure.

2. Can overclocking damage the CPU? Yes, overclocking can potentially damage the CPU if done improperly or if temperatures exceed safe limits.

3. How can I safely overclock my CPU? Proper overclocking requires careful adjustments of voltage and clock speed, along with effective cooling solutions.

4. What is a safe temperature range for a CPU? Most CPUs operate safely below 90 degrees Celsius, but it is recommended to keep temperatures below 80 degrees Celsius for optimal performance and longevity.

5. Will overclocking improve gaming performance? Overclocking can improve gaming performance by providing higher clock speeds, resulting in better frame rates and smoother gameplay.

6. Will overclocking void my warranty? Yes, overclocking is generally not covered under warranty. However, some manufacturers offer CPUs specifically designed for overclocking.

7. How can I revert overclocked settings? Enter the BIOS settings and restore default values or select an option to disable overclocking.

In conclusion, determining if your CPU is overclocked requires a combination of software monitoring, hardware inspection, and performance testing. Understanding the risks and limitations of overclocking is crucial to ensure the stability and longevity of your system.
