How To Undervolt GPU?  The Ultimate Guide to Undervolting Nvidia’s GPU

Before we start to know the basics of the undervolting process let me give you some core concepts about undervolting first. Undervolting is the process of dynamic voltage scaling that reduces the power consumption and heat of other components.

Undervolting GPU sometimes increases the performance, lowers the power, and also resists heat and noise scales. Undervolting is not a big issue now you can easily crack its methods by simply knowing its basic steps. Give it a read so you can find the best ways of undervolting.

What is Nvidia Graphics Card Undervolting?

It takes a few steps to undervolt a GPU. This guide works well with Nvidia GPUs that are Pascal or newer. We will review them and go through these steps to make it easier for you. 


Things to Know First

Undervolting a GPU is a great initiative to improve the performance Of GPU to some extent but before proceeding to this process you must be aware of the fact that not every GPU can be Undervolted. In addition to undervolted processes not being allowed in below-dated models, Nvidia’s 10 series is banned as well.

This reason is due to the locking of voltage in the previous pascal series. It results that most top undervolt tools did not support these cards

Undervolting a GPU

To know the steps of undervolting GPUs, we will go through a few steps. Let’s begin.

This is the most in-demand tool of undervolting for Nvidia graphics cards. Let’s go through a step-by-step process to find out how to undervolt a GPU. 

1: Downloading MSI Afterburner

This is the most in-demand tool for undervolting Nvidia graphic cards. Begin this process by downloading the program.

Launch it after installing your PC.

2: Accessing the Curve Editor

Move the cursor towards the MSI Afterburner interface, You will receive information about the voltage of your GPU. On the lower side, you can simply find the Curve Editor. You can get access by double-clicking or by pressing CTRL + F.

When the Curve Editor is open, a Graph will be shown.

This graph contains two essential pieces of information. The X-axis is the Voltage of the card while the Y-axis tells us about the frequency ( speed of the clock).

3: Testing The Graphics Card

Taking further steps, you must know the frequency of your GPU running under stress. Launching a GPU-intensive program and running a stress test are two ways of doing this.

To launch a heavy game you must run it for a few minutes. Sometimes games rely on processors rather than graphics cards, but these put high pressure on the GPU for showing exact frequency especially on higher resolutions.

After launching the program first, confirm that you are using a windowed mode, remember the “MHz” labeled and number. Here it will be 1877MHz approximately.

4: Correct Axis Finding in Curve Editor

In Afterburner, open the Curve Editor tool and locate the right frequency on the Y-axis. Click on the dotted curve line until you see the correct frequency on the left side, aligned with the curve. The voltage will be 1873MHz, which will require a voltage of 1000.

5: Selecting New Voltage

Undervolting GPU cannot be considered the exact way. The reason is it is all about trials and errors. undervolt it by Doing it little by little will be the best suggestion than doing it too much at one time.

A desirable voltage can be selected. The particular number is knotted with a lower frequency. Moreover, there are some ways to fix it.

6: Core Clock Adjusting

When the step of picking Voltage is completed Go back to the window Of MSI Afterburner and see the clock (MHz) section.if You want to adjust the core clock matches the voltage to your card’s frequency for maintaining it.

Increase the core clock in the curve editor to make the curve change. Find the voltage that you chose earlier at the bottom and frequency on the left. Keep the increasing process for some while so that your frequency is the same while running on the lowered voltage.

The results will be shown like your card will run on the same frequency before maintaining the maximum voltage of your choice. These all numbers should be following those values that you choose in the first step. 

7: Keeping Core Speed and Voltage

Changing the core clock, adjusting easily, now it’s time to make sure that the values should be maintained and don’t go up above the chosen value.

In the Curve Editor, click on the voltage of your desire. From the desired voltage point, drag down the small squares to the area where you made highlights. If it seems to be difficult just make the remainder of the curve below the peak of the frequency area.

8: Save and Adjust

To maintain these changes, move back to the MSI Afterburner window and click the Floppy disk icon (Save)  at the bottom of the screen.

The new frequency and voltage both will be put on testing by the same game, another heavy application or program. Then Trace the values in MSI Afterburner for making it clear that you are using the same frequency as you did to undervolting GPU 

Now the game should be run for 15 minutes to check if everything goes well. And if it works well, then there is no issue with the Card, while when it is not working re-do the steps again.

9: Stress-Test the Card

As you know, this is considered an extra step, but it is essential. When you are sure about the new settings, then no matter what the circumstances may be, your card will work optimally. Games will work normally but some programs will stress the card in other ways.

If everything works well and there is no issue you are facing, then congratulations you just achieved it, fortunately, you learned how to undervolt the Nvidia GPU.

Can undervolting hurt the GPU?

Ans: Undervolting is a safe process. It increases the performance of your GPU, lowers heat production, step-by-step  and decreases noise.

Does undervolting reduce GPU life?

Ans. In short, undervolting GPUs is completely safe and it will not affect your GPU. Overvolting causes major damage to the GPU, but undervolting will not affect it at all.
