How To Overclock a GPU?

Overclocking a graphics card can make it run faster. This is done by increasing the clock rate or the GPU’s speed. By doing this, you can get more performance from your graphics card without having to buy a new one. There are many games like Call of Duty Warzone that requires some overclocking.

In order to overclock your graphics card, you will need some software and some knowledge of how to do it.

There are a few things to keep in mind when you overclock your GPU. The first is that you need to make sure that your computer can handle the increase in speed. If you don’t have a good enough power supply or your cooling isn’t good enough, you could damage your GPU.

Second, you need to find the right clock rate and voltage combination. Too much of either one can hurt your GPU. Finally, it would help if you were careful about pushing your graphics card too hard. If you overclock it too much, it could break, and you would have to buy a new one.

What is Overclocking?

So you must know the mechanism of overclocking so you can better understand it. But before we touch on the overclocking topic, let me tell you how a GPU works.

A GPU is a tiny computer that sits on your graphics card. Its job is to take the data from your computer’s memory, process it, and then send it back to the display. The speed at which a GPU can do this is determined by its clock speed.

The higher the clock speed, the faster the GPU can process data.

These clocks are packed with factory settings, and they ensure that your GPU runs at its best. But what if you want to get even more performance out of your card? That’s where overclocking comes in.
Overclocking is the process of making a computer or component run at a higher speed than it was intended to.

For example, if you have a CPU with a clock speed of 3.0 GHz, you can overclock it to run at 4.0 GHz. This will make your CPU run faster, but it will also generate more heat and use more power. So why would you want to do this?

The answer is simple: performance. When you overclock a component, you’re essentially making it faster. This can be useful for gaming, video editing, or other resource-intensive tasks. It can also help you squeeze more life out of an aging component.

Now that we know what overclocking is let’s look at how you can do it on your own GPU.

Now finally, we are going to overclock a GPU. Just like with CPUs, there is a risk involved when overclocking a GPU. By overclocking your GPU, you can increase your gaming performance. Most GPUs will run at default without any issues, but you can get more performance out of it by overclocking. The first thing you want to do is figure out what your baseline overclock is going to be. You can do this by opening up a GPU-intensive game and seeing your framerate. Once you have your baseline, you can start overclocking your GPU.

There are a few things to keep in mind when overclocking your GPU. The first thing is to not overclock too much at once. Start with a small overclock and then slowly increase it until you reach your desired overclock. The second thing is to keep an eye on your temperatures. You don’t want to overheat your GPU, so make sure to keep an eye on the temperature of your GPU while you are overclocking it.

Step 1 – Benchmarking Test

Benchmarking is very necessary before hitting your card your overlock. You can get a good idea of your card’s potential and your overclock’s stability in benchmarking tests.

There are a lot of different benchmarking tools out there. For this guide, we will be using Heaven Benchmark.

Once you have downloaded and installed Heaven Benchmark, open it up and click on the “Benchmark” button.

After the benchmark is finished, you will see a screen with your score and your average framerate. Write down your score and your average framerate.

Step 2 – Overclocking the GPU

Now that we have our baseline, we can start overclocking our GPU. For this guide, we will be using MSI Afterburner.

  1. Once you have downloaded and installed MSI Afterburner, open it up.
  2. On the main screen, you will see a bunch of different settings. The first thing we are going to do is increase the power limit. To do this, find the “Power Limit” slider and slide it to the right.
  3. The next thing we are going to do is increase the GPU clock speed. To do this, find the “GPU Clock” slider and slide it to the right.
  4. You will want to increase the GPU clock speed in small increments. For this guide, we will be increasing it by 10 MHz at a time.
  5. After you have increased the GPU clock speed, click on the “Apply” button.
  6. Now open up Heaven Benchmark again and run the benchmark.
  7. Once the benchmark is finished, check to see if your score has increased and if your average framerate has increased. If it has, then you have successfully overclocked your GPU. If not, then increase the GPU clock speed again and repeat the process.

Step 3 – Monitoring Your Temperatures

Now that you’ve overclocked your GPU, it’s important to keep an eye on your temperatures to ensure that you’re not pushing your card too hard.

There are a few different ways to monitor your temperatures. The first is through your graphics card’s control panel. Both NVIDIA and AMD have utilities that will allow you to monitor your GPU temperature in real-time.

Another way to monitor your temperatures is through third-party software such as MSI Afterburner, EVGA Precision X, or Sapphires TRIXX. These programs allow you to monitor your GPU temperature and give you the ability to control your fan speed and make other adjustments.

Finally, you can also check your GPU temperatures by opening up your case and using a handheld temperature gun to measure the card’s temperature.

Whichever method you choose, just be sure to keep an eye on your temperatures and make sure they don’t get too high. If they start to climb too high, you can back off on your overclock or add additional cooling to your system.

Step 4 – Adjusting Your Overclock Settings

Once you’ve got your overclock dialed in and you’re happy with the results, it’s time to start fine-tuning things to get the most out of your card.

The first thing you’ll want to do is experiment with different voltages. Higher voltages will allow you to achieve higher clock speeds, but they also increase the amount of heat your card produces. You’ll want to find a balance that works for you.

Start by raising the voltage in small increments and testing stability at each step. If you start having problems, back off and try again. Once you’ve found a stable voltage, you can start pushing your clock speeds higher.

Another thing to remember is that not all cards will overclock the same. Some cards will achieve higher voltages and clock speeds than others. It’s essential to find out what your card is capable of and not push it too hard.


Overclocking your GPU can be a great way to get more performance out of your system. With a little bit of patience and experimentation, you can find the perfect overclock for your card. Remember to keep an eye on your temperatures and don’t push your card too hard. happy overclocking!
