Laptop CPUs

Almost all laptops don’t support CPU overclocking.

Only high-end laptops dedicated to gaming, programming, or video editing have CPU overclocking capabilities, and their manufacturers specifically state that they’re overclockable in their specifications.

If you have a laptop and it’s not a high-end one, your CPU isn’t overclockable.

 

Intel CPUs

Intel has a “K” series among its CPU models, referring to the “Unlocked” CPUs.

Simply put, if the name of your CPU model ends in the letter “K,” you can overclock it.

For example, the Intel Core i7 11700K or the Intel Core i5 10600K are overclockable.

Also, the Intel Pentium G3258 CPU is overclockable, as well.

 

AMD CPUs

The FX series is unlocked and can be overclocked among the AMD CPU models.

The AMD CPUs that end their name in “K” are also overclockable.

 

3. Ensure If Your Motherboard Has Overclocking Abilities

If your CPU is one of those with overclocking abilities, you need to check your motherboard next.

A quality motherboard with a solid Voltage Regulator Module will ensure the stability of your system and longevity of your components when you overclock your PC.

You’ve found your motherboard model in the previous step.

Search online for its overclocking capabilities and make sure it can perform well.

 

Understanding Overclocking

Before we start with identifying the overclocking abilities of your CPU, you need to learn about a couple of technical features.

CPUs have independent processing units named cores that can execute program instructions.

The more cores your CPU has, the better its performance and efficiency, especially in heavy tasks.

Each CPU has a dedicated clock speed which refers to the operational and processing speed of the CPU cores.

It shows the number of cycles a core performs per second, measured in Hertz.

The faster the clock speed, the faster the CPU can execute different tasks.

Overclocking is the process of increasing the clock speed of a CPU more than the clock speed the manufacturer has set for it originally.

The clock speed has three measures:

  • Base Frequency: The base frequency of your CPU refers to the clock speed at which the CPU operates when your system is in an idle state.

It means it’s not under stress and performing lighter tasks.

The manufacturer specifies this number in the CPU’s specifications.

  • Turbo Frequency: The Turbo frequency is the maximum clock speed the CPU can achieve when performing heavier workloads.

Most mainstream CPUs have their Turbo frequencies listed under their specs, but entry-level CPUs don’t have this information.

  • Overclocked Frequency: When the Base and Turbo frequencies are set to higher numbers than the manufacturer has specified, your CPU will be operating at the Overclocked frequency.

 

How To Check If Your CPU Is Already Overclocked?

There can be many reasons someone would want to check if their CPU is overclocked.

Your system might be performing out of balance, and you might want to look into the CPU frequency as a culprit.

Moreover, you might have just overclocked your CPU, and you might want to check whether the process was successful or not.

However, you should know that overclocking isn’t an automated process, and it doesn’t happen to the CPU unless the user does it.

Also, CPUs don’t come overclocked when you first buy and install them.

Therefore, if you haven’t tweaked anything, don’t worry about your CPU being overclocked.

To find out if your CPU is overclocked or not, you first need to know its base and turbo frequencies.

Take the name and model of your CPU that you found in the previous sections and search for it online to find out its original clock speed.

  • Next, you should run a stress test to put a heavy load on your CPU and measure its speed.
  • There are various websites and applications you can use for this matter. Here are some of the best stress testing tools you can download:
    • CPU Expert
    • CineBench
    • GIMPS
    • HeavyLoad

Now, use one of the following methods to determine what speed your CPU is working at right now.

Compare it to the original clock speed, and if it’s more than it should be, your CPU is overclocked.

 

1. Task Manager

  1. Right-click on the Start button and choose Task Manager from the list.
  2. Head to the Performance tab and check the provided speed.
  3. Run the stress test of your choice to put a load on your CPU and check the Speed value.
  4. Compare the Speed value with the Turbo value you’ve found online.

If it’s more, your CPU is overclocked.

  1. You can also see the Base Speed of your CPU in the Task Manager window and compare it to the Base speed number you’ve found online.

 

2. CPU-Z

As mentioned earlier, CPU-Z is a free tool you can install to get all the detailed information you’ll need about your hardware.

  1. Download and install CPU-Z according to your PC architecture (32bit or 64bit.)
  2. Once you open the app, it should be on the CPU tab.
  3. Find the Clocks section.
  4. Locate the Core Speed option that displays the current frequency of your CPU.
  5. Run a stress test and check the Core Speed value.
  6. If its number exceeds the Turbo frequency, your CPU is overclocked.

 

3. DirectX Diagnostic Tool

  1. Many computers come with the DirectX Diagnostic Tool pre-installed.
  2. Hit the Windows + R key to open the Run window and paste “dxdiag” in the command box.
  3. Hit Enter to run the command.

If the Diagnostic Tool doesn’t open up, you’ll have to download and install it on your PC.

  1. Once you’re in the app, head to the System tab.
  2. Locate the Processor information with the current speed of the CPU listed.
  3. Run the stress test and check out the speed.

If it’s higher than the Turbo speed, your CPU is overclocked.

 

4. HWiNFO App

Another app that provides you with your system information is the HWiNFO app that you can download and install easily.

  1. Run the app and head to the Performance tab.
  2. Expand the central Processor section.
  3. Run the stress test and watch the CPU Speed.
  4. If it exceeds the Turbo frequency, your CPU is overclocked.

 

5. BIOS

The last and most advanced method for checking whether your CPU is overclocked is through the System BIOS.

  1. First, you need to enter the BIOS interface.

Most newly-manufactured computers have the same method of entering the BIOS.

You’ll have to press one of the following keys on your keyboard while the computer is booting up:

  • F1
  • F2
  • F10
  • Del
  • Esc
  1. Since your computer’s details might be unique, consult your computer or motherboard manual or the manufacturer’s official website to find out how to enter the BIOS.
  2. Once you’re in the BIOS interface, head to the CPU Settings.

Depending on your motherboard model and BIOS version, this option could have different names.

  1. Look for CPU clock, clock multiplier/clock Ratio, and CPU Voltage settings.
  2. If these are set to higher than what you found online, your CPU has been overclocked.

 

Downsides Of Overclocking

After finding out if your CPU has been overclocked, you should decide if you want to keep it that way or not.

Overclocking gives your system performance a significant boost.

However, it comes with its own risks and drawbacks.

 

1. Stability Issues

If you’re not careful with overclocking, it can lead to stability issues in your System.

You might experience bluescreens, freezes, and similar system errors.

Your PC might even shut down all of a sudden to protect its components from further damage.

 

2. Overheating

The CPU generates heat while operating in its normal state.

It’ll start overheating if you overclock your CPU and put a huge load on it.

You need to prepare your setup for overclocking and install a powerful airflow heatsink or an All-in-One (AIO) water cooling unit to cool down your CPU.

 

3. High Voltage Requirements

The more work your CPU does, the more power it’ll need to stay functional.

Your PSU needs to provide the high voltages your overclocked CPU needs.

Therefore, you’ll need a high-quality and reliable PSU with a Bronze, Gold, or Platinum certification, or else your CPU will get damaged.
