How to Overclock your GPU

A GPU (graphics processing unit or graphics card) contains chips that can work faster and better with the right approaches and interventions. People overclock their GPS to improve its performance. This is less costly than getting a new card.

Know Your GPU

Before you can overclock your GPU, you need to know its specs, such as standard clock speeds for the memory and core, standard load and idle operating temperatures, and performance. To find this information out, download MSI Afterburner, AMD Wattman, or another overclocking tool – there are many alternatives on the market.

Close down all apps that are running and launch MSI or AMD. If you choose the former, which we recommend, click the “Settings” button and then select “User Interface” via the top-tab navigation arrows. Use the drop-down menu in the “User interface skinning properties” heading to choose “Default MSI Afterburner v3 skin.”

If you want to convert readouts from Fahrenheit to Celsius or vice versa, use the temperature settings. Most of the information on your GPU’s specs is available in MSI in the graphs on the right-hand side. The top graph displays the core temperature of the GPU. The ones beneath it display the core clock and memory clock – the numbers that need to be changed. The idling speeds are indicated in the “Min” section, while “Max” displays the load speeds.


Update and Reboot

You need to update your graphics drivers to the latest versions, which you can find on AMD or Nvidia’s websites. You will also need a benchmark to assess the stability of your GPU. We recommend the user-friendly Unigine’s Valley – it has stood the test of time.

Don’t forget to check the temperature regularly. Your cooling system isn’t strong enough to accommodate overclocking if the temperature is over 176 degrees Fahrenheit.





Stress Test

In “Windowed” mode, launch the Unigine stress testing app. Increase the power limit to the max in the Afterburner window — that lets your graphic card use as much power as it needs. In the Afterburner window, type in the number or use the slider to raise your clock speed by 10MHz. Return to the Unigine window and watch for signs that the graphics chip may be overexerted, such as big bands of color or small blocks of mis-colored pixels.


Final Steps

Go back to the Afterburner window and repeat the process if you don’t see any of those. Keep doing this until you see these signs. If your screen goes black, that means the Unigine has crashed. Reduce the speed by around 15Mhz and re-launch it. When it becomes stable, that means you’ve reached optimal speed. Overclocking is complete.
