Overclocking a Nvidia GPU refers to the process of increasing the clock speed and voltage of the graphics processing unit beyond its default settings to increase its performance. It can be a useful technique for those looking to improve their system’s gaming or rendering performance, but it should be done with caution and only by experienced users.

Before attempting to overclock your Nvidia GPU, it’s important to understand the risks involved. Overclocking can lead to increased power consumption, heat generation, and instability, which can result in system crashes or even permanent damage to your GPU. Therefore, it’s important to have a good cooling solution, such as a high-quality CPU cooler, to prevent overheating.

Advantages of overclocking Nvidia GPUs

There can be several advantages to overclocking an Nvidia GPU:

Improved Performance: Overclocking your Nvidia GPU can increase its clock speed and memory speed, resulting in faster processing times and improved performance in graphics-intensive applications such as games and rendering software.
Better Gaming Experience: By overclocking your Nvidia GPU, you can achieve higher frame rates in games, resulting in a smoother and more responsive gaming experience. This can be especially beneficial for gamers who want to achieve the best possible performance from their system.
Cost-effective Upgrade: Overclocking your Nvidia GPU can be a cost-effective way to upgrade your system’s performance without having to purchase a new graphics card. This is particularly useful for users on a budget who cannot afford to buy the latest and most expensive GPUs.
Customizable Performance: Overclocking your Nvidia GPU allows you to fine-tune its performance to your specific needs. You can adjust the clock speed, voltage, and memory speed to achieve the optimal balance between performance and stability.
Competitive Advantage: Overclocking your Nvidia GPU can give you a competitive advantage in gaming tournaments and other graphics-intensive competitions. By achieving higher frame rates and better performance, you can gain an edge over your competitors.

Disadvantages of overclocking Nvidia GPUs

While overclocking your Nvidia GPU can provide some benefits in terms of increased performance, there are also several disadvantages to consider:

Reduced Lifespan: Overclocking a GPU can significantly reduce its lifespan. When you overclock a GPU, you are pushing it beyond its rated specifications, which can cause damage over time. This is because overclocking can cause the GPU to operate at higher temperatures, which can lead to component degradation and failure.
Increased Heat: Overclocking your Nvidia GPU can generate more heat than it was designed to handle, which can cause instability and crashes. If your cooling system is not sufficient to handle the extra heat generated by the overclocked GPU, you may experience system crashes and other issues.
Voided Warranty: Overclocking your Nvidia GPU can void your warranty. Manufacturers typically do not cover any damage caused by overclocking since it is considered an unauthorized modification of the hardware.
Power Consumption: Overclocking your Nvidia GPU can significantly increase its power consumption, which can cause stability issues and even damage to your power supply unit (PSU). If your PSU is not designed to handle the increased power demand, it can lead to system crashes and other issues.
System Instability: Overclocking your Nvidia GPU can cause system instability, which can result in crashes, freezes, and other issues. This is because overclocking can cause the GPU to operate outside of its rated specifications, which can lead to unpredictable behavior.

How to overclock Nvidia 660 GPU in your Windows PC?

There are two tools we shall be using in order to overclock our Nvidia graphics card. First, we will need an overclocking software in order to boost our graphics card parameters. The best overclocking software in the market currently is the MSI Afterburner. It’s a very easy to use tool for newbies as well as professionals, and is always kept updated with the latest GPUs. The best part is that MSI Afterburner works on all non-MSI graphics cards.

Download MSI Afterburner

Overclocking an Nvidia graphics card pushes the graphics card to its limits, so we shall need a tool to benchmark its performance and ensuring that we are not overstressing our graphics card. This helps determine the best parameters for your particular graphics card. For our tutorial, we shall be using the Geeks3D FurMark software for our GPU benchmarking.

Download Geeks3D FurMark

Once you have downloaded both the tools, install the software in your system and you are ready to proceed further with this guide.

Note: For this tutorial, I shall be using my Nvidia GTX 1650 for demonstration purposes.

Note the current system settings and benchmark the performance
1. Press the Windows key to open the start menu, search for FurMark and open the application.
2. Click on GPU-Z in the bottom left corner of the application and grant Administrator access when prompted by Windows.
3. This will launch a separate window. Take note of the highlighted parameters before proceeding further with the tutorial.
5. Click on Close.
6. Back on the FurMark application, maintain all the default settings and click on Custom preset.
8. A warning message will be displayed, click on GO!
This will launch a 60 second long GPU test, kindly be patient while the test completes. Once its done, a results window will be displayed. Take note of all the parameters as this will be the standard we shall be comparing our overclocked results against.

Overclock your Nvidia GPU
1. Click on Windows icon to launch the start menu, search for MSI Afterburner and launch the application. Provide Administrator permission when prompted by Windows.
2. As a general rule of thumb, raise the Core Clock and Memory Clock rate by 5-10 Mhz or by 10% of the original values, and then click on the Apply button in the bottom of the application. After doing this, benchmark the graphics card performance using FurMark as demonstrated earlier until you see no more improvement or the test crashes.
4. For my Nvidia GTX 1650, I found the sweet spot for my graphics card at +~200 Core Clock and +~750 Memory Clock. Use the GPU-Z utility inside FurMark to confirm these changes.
6. For these values, I got the new results at roughly +10 FPS. You can definitely push more than these values but I did not want to over exert my graphics card. Please remember that it is very important not to push the limits too much as there are multiple disadvantages with doing as was highlighted earlier.
8. Once you find the values for your graphics card, you can save them to one of MSI Afterburner profiles for future use.

Most common mistakes while overclocking

We would like to highlight the mistakes most people make very commonly while trying to overclock their Nvidia GPU.

Increasing values rapidly: If you raise your clock frequencies too quickly, there is a high chance that you will experience crashes, glitches, or even a black screen.

Going without testing: Not testing out the performance of the graphics card after an incremental clock increase prevents you from monitoring system performance at given clock speeds. It is very easy to go too far if you don’t test properly at regular intervals.

Overheating: Overclocking your GPU increases its heat output. To protect your computer from overheating, you’ll want a custom-made card with sufficient cooling ability, or even a water-cooling system in your PC.

Auto-overclocking: Your GPU works harder when it’s overclocked, so you don’t need to overclock it continuously. Use MSI Afterburner’s profile system to save your overclock, and use it only when running a demanding game or application.

Expecting too much: Even when overclocked, an older GPU will never match the performance of the latest high-end cards. At most, you can expect performance to increase by 10 to 20%.
