How To Undervolt GPU – A Complete Undervolting Guide

Every GPU needs to refresh after a few times, whether it is the latest or high-end graphics card or you are using an older version of the graphic card. Undervolting is necessary because it can reduce power consumption, temperature, noise, etc. Apart from this, it is also well known for improving the performance of the CPU when it gets a little bit older.

It is essential to know how to under-volt your graphic processing unit. Some of the basic things you need to learn are as follows. After that, you are getting the under-volt graphic card on your own would be very easy. However, before you begin, you must know that undervolting cannot be done to every GPU. For example, NVIDIA models do not allow their GPU to under-volt.

The main reason behind that is that NVIDIA cards have a voltage lock. Many popular undervolting tools do not support every NVIDIA card. However, the new card offered by NVIDIA does not have a complex process; they are easy, and their voltage is unlocked. AMD cards are well known for their undervolting because even older versions have the capability of undervolting. Their clock speed, power, and temperature can be visible while doing this process at a lower voltage.

How to undervolt NVIDIA graphic card?

It cannot be easy to do on an NVIDIA card compared to AMD, but it can still be possible by the following step.

  1. Download MSI afterburner – First and foremost, you must download the MSI tool specially designed for NVIDIA graphic cards, install it on your computer, and launch it.
  2. Access the curve editor – After opening the MSI afterburner interface, you will find the information about the voltage on the lower part of your tool, and there you have to find the curve editor. Again, it is easy to access; you have to press CTRL + F. You will find a graph after entering, and this graph includes essential information on the voltage of your card; it shows the frequency and clock speed of your graphic card.
  3. Test your graphic card – Initially, you must find out the frequency your GPU runs at critical conditions; you can do it easily by running a simple stress test. Or you can also play a heavy-duty game for at least 15 minutes; this will help the tool know the correct frequency of your GPU.

After the launch of your program, you should check the labeled MHz and note down the number.

  • Find the correct axis in the curve editor – You should open the tool again afterburner to find the right frequency on the Y axis. Then, you must click continuously along the dotted line until you find the correct frequency on the left-hand side. After that, look down and check the corresponding voltage.
  • Pick your new voltage – The process of undervolting in the NVIDIA graphic card might be very time-consuming, and you have to try it repeatedly to complete the undervolting. Therefore, it would be ideal for you to undervolt the GPU slowly. 
  • Adjust the core clock – Now, look for the core clock section, and you have to adjust the core clock. Adjust so that your card’s frequency matches the voltage you want to maintain. You have to do it until the curve changes. Keep increasing the o’clock and stop when it reaches the stress level frequency.
  • Maintain speed and voltage – When you have successfully changed the speed of your clock and the voltage of your graphic card, you have to ensure that the value does not exceed the value you have fixed. Again open the curve editor to change something. Adjust the value properly so that your GPU will provide a stable performance at that clock speed.
  • Save and adjust – After completing the process, you can press the floppy disk icon, which you can find at the bottom of the screen, and this icon will help you save every setting you have done to your GPU.
  • Stress the test card – Finally, after settings are saved, you can run a test to check the performance of your Undervoltage card. You can create any circumstances and make a proper stress test. Check the benchmark score after the test and compare it to the previous test; you will see the changes in many aspects of your NVIDIA graphic card.

How to undervolt an AMD graphic card

Undervolt AMD Graphic Card

To under-volt and AMD cards are straightforward compared to NVIDIA because AMD already includes the entire tool needed for undervolting in their drivers. So this saves you plenty of time.

  1. Enter the Radeon control panel – You can easily access the radio and control panel because AMD has already installed every program in a there graphic processing unit.
  2. Open Radeon wattman – The radio and control panel user interface may look different according to different GPUs and drivers, but it is easy to navigate. You will find a gaming section on the topmost part of the screen and click on enter.

Now open global setting and then global wattman. Click end and accept the warning that AMD will show you; after reading that, completely accept it and launch Radeon Wattpad. 

  • Test the optimal frequency of your GPU – Just like NVIDIA; you have to run a 15-minute of test to check the frequency of your GPU. You can play a game for at least 15 minutes to process further steps.
  • Adjust the voltage and frequency – Now, navigate toward the voltage and frequency sections. The settings should be auto; you must take it in your hand by making it manual. You have to drag the voltage value lower than your card’s maximum value to perform undervolting.
  • Now run a test – To ensure the quality of your GPU performance after undervolting, you must perform a test again and compare it to the previous one.

These were the few steps necessary to undervolt the graphic processing unit AMD and NVIDIA. As you have already seen that there were many steps in undervolting NVIDIA while on the other hand, it was straightforward to undervolt the AMD. Therefore, the above guide will make it easy for you to complete the process without complications.
