What is Undervolting?

Undervolting is the process of reducing the voltage supplied to a graphics card, processor, or other electronic device. This can be done in order to reduce power consumption and heat output, or to improve performance.

Definition of Undervolting

Undervolting is the act of reducing the voltage supplied to a component in order to achieve a desired result. In the case of graphics cards, undervolting can be used to reduce power consumption and heat output, or to improve performance.

Benefits of Undervolting

There are several benefits to undervolting a graphics card, including:

• Reduced power consumption: Undervolting a graphics card can reduce its power consumption by up to 20%. This can save you money on your electricity bill, and it can also help to extend the life of your graphics card by reducing the amount of heat it generates.
• Reduced heat output: Undervolting a graphics card can also reduce its heat output by up to 20%. This can make your graphics card run cooler and quieter, and it can also help to improve its performance.
• Improved performance: Undervolting a graphics card can sometimes improve its performance. This is because a lower voltage can allow the graphics card to run at higher clock speeds without overheating.

Risks of Undervolting

There are some risks associated with undervolting a graphics card, including:

• Instability: Undervolting a graphics card too much can cause it to become unstable. This can lead to crashes, artifacts, and other problems.
• Reduced performance: Undervolting a graphics card too much can also reduce its performance. This is because a lower voltage can limit the graphics card’s ability to run at high clock speeds.

How to Undervolt a 4090?

Undervolting a 4090 is a relatively simple process, but it does require some care and attention. In order to undervolt your 4090, you will need the following:

• A graphics card with a 4090 chip
• A computer with Windows 10 or Linux
• A graphics card overclocking utility (such as MSI Afterburner or EVGA Precision X1)

Steps to Undervolt a 4090

To undervolt a 4090, follow these steps:

1. Download and install a graphics card overclocking utility.
2. Open the overclocking utility and select your 4090 graphics card.
3. Click on the “Voltage” tab and reduce the core voltage by 50mV.
4. Test your graphics card by running a stress test.
5. If the graphics card is stable, reduce the core voltage by another 50mV.
6. Repeat steps 4 and 5 until the graphics card becomes unstable.
7. Increase the core voltage by 10mV and test the graphics card again.
8. Repeat steps 4-7 until you find a stable voltage that provides the desired performance improvement.

Tools and Software Needed

In order to undervolt a 4090, you will need the following tools and software:

• A graphics card with a 4090 chip
• A computer with Windows 10 or Linux
• A graphics card overclocking utility (such as MSI Afterburner or EVGA Precision X1)

Potential Problems and Solutions

There are a few potential problems that you may encounter when undervolting a 4090, including:

• Instability: If you undervolt your 4090 too much, it may become unstable. This can lead to crashes, artifacts, and other problems.
• Reduced performance: Undervolting a 4090 too much can also reduce its performance. This is because a lower voltage can limit the graphics card’s ability to run at high clock speeds.

If you experience any of these problems, you can try increasing the core voltage until the problem is resolved.

Undervolting is a safe and effective way to improve the performance and efficiency of your 4090 graphics card. By following the steps in this guide, you can easily undervolt your 4090 and enjoy the benefits of reduced power consumption, heat output, and improved performance.

3. Testing Your Undervolt

Once you have applied an undervolt to your graphics card, it is important to test it to make sure that it is stable. This can be done by running a stress test. There are a number of different stress tests available, but one popular option is FurMark.

To run FurMark, simply download the application and install it on your computer. Once it is installed, open the application and click on the “Stress Test” button. This will start the stress test and your graphics card will be put under load.

The stress test will run for a set amount of time, typically 10 minutes. During the stress test, you should monitor your graphics card’s temperature and performance. The temperature should not exceed the manufacturer’s recommended maximum temperature, and the performance should not drop below the expected levels.

If your graphics card’s temperature or performance does not meet the expected levels, you may need to adjust your undervolt. To do this, simply decrease the voltage by a small amount and then re-run the stress test. Repeat this process until you find a voltage that is stable.

4. Troubleshooting Undervolting Issues

There are a number of common problems that can occur when undervolting a graphics card. These problems include:

• Stability issues: The most common problem with undervolting is instability. This can manifest itself in a number of ways, including crashes, graphical glitches, and artifacts.
• Performance issues: Undervolting can also lead to performance issues. This can happen if the voltage is too low and the graphics card is not able to maintain its performance under load.
• Temperature issues: Undervolting can also lead to higher temperatures. This is because the graphics card is not able to draw as much power as it would at stock settings.

If you experience any of these problems, there are a number of things you can do to troubleshoot them. These include:

• Reducing the voltage: If your graphics card is unstable, try reducing the voltage by a small amount. This may help to stabilize the card and reduce the likelihood of crashes.
• Increasing the power limit: If your graphics card is experiencing performance issues, try increasing the power limit. This will allow the card to draw more power and may help to improve performance.
• Using a more aggressive fan curve: If your graphics card is overheating, try using a more aggressive fan curve. This will help to keep the card cooler and may help to prevent thermal throttling.

If you are unable to resolve the problem, you may need to return your graphics card to the manufacturer or exchange it for a new one.

Undervolting a graphics card can be a great way to improve performance and reduce power consumption. However, it is important to do it correctly in order to avoid stability and performance issues. By following the steps in this guide, you can safely and easily undervolt your graphics card and enjoy the benefits it has to offer.

How do I undervolt my 4090?

There are a few different ways to undervolt your 4090. The easiest way is to use a third-party software tool, such as MSI Afterburner or EVGA Precision X1. These tools allow you to adjust the voltage and clock speed of your graphics card, which can help to reduce power consumption and heat output.
