Undervolting GPU boosts performance and cuts heat. Unsure how to undervolt GPU? We’ve got you covered! By adjusting your GPU’s voltage settings, you can reduce energy usage, lower heat production, and extend the lifespan of your graphics card.
In this article, we’ll delve into the step-by-step process of undervolting your GPU while providing you with the tools and knowledge to optimize its performance safely.
What Is GPU Undervolting?
GPU undervolting involves reducing the voltage supplied to your graphics card’s GPU in order to improve performance and reduce power usage. Every graphics card comes with a preset voltage from the manufacturer, but often it’s set higher than needed for stability. By slightly reducing the voltage, you can achieve a more optimal power balance.
How Does It Improve Performance?
When a GPU receives too much voltage, it creates excess heat which can throttle performance. Undervolting lowers the temperature, allowing the GPU to sustain higher clock speeds for longer. This results in a faster, more stable GPU that can achieve maximum performance during gaming or other intensive tasks.
Is It Safe?
Undervolting is generally safe for your graphics card if done properly in small increments. However, reducing the voltage too much can lead to system instability and crashes. It’s best to undervolt in small steps, testing for stability after each change. Some signs your GPU is undervolted too much include:
- Screen artifacts or glitches appearing
- System freezing or crashing during graphics-intensive tasks
- BSOD (blue screen of death) errors mentioning the graphics card
If you experience any of these issues, simply raise the voltage slightly until the problems disappear. When done correctly, undervolting should not damage your graphics card or other components. However, it can void your graphics card’s warranty, so proceed with caution.
How Do I Undervolt My GPU?
To undervolt your GPU, you can lower its power and heat without losing performance. Try adjusting small voltage settings and test carefully for stability and performance. Keep in mind that different GPUs may have different results.
Why Undervolt Your GPU? The Benefits
Undervolting your graphics card or GPU is a great way to improve its performance and efficiency. By slightly reducing the voltage to your GPU, you can lower its power consumption and heat output without significantly impacting performance. This means your GPU will run cooler and quieter, reducing fan noise and increasing its lifespan.
1. Improved Stability and Lifespan
Operating at a lower voltage and temperature, your GPU components are under less stress. This results in increased stability and a longer lifespan, as high heat is damaging to electronics over time. Undervolting can add months or even years to your GPU’s working life.
2. Lower Power Consumption
Even a small reduction in voltage can lead to a meaningful drop in power usage. Your GPU has to work less to operate, so it consumes less energy. For laptop users especially, this can translate into longer battery life and less time spent plugged in. The power savings may seem minor at first but can really add up over the lifetime of your graphics card.
3. Cooler and Quieter Operation
With less power and heat being generated, your GPU fans don’t have to work as hard to keep temperatures in check. This means quieter fan noise coming from your computer, which many people find annoying or distracting. The drop in temperature also means your other components like the CPU will stay cooler, as graphics cards can heat up the entire system.
4. Minimal Impact on Performance
When done properly, undervolting should not significantly reduce your GPU’s performance. You may see a small drop of a few percentage points in benchmarks, but for most real-world usage like gaming, video editing or streaming, you won’t notice a difference. The performance impact depends on your exact graphics card and how aggressively you undervolt, so do some testing to find the sweet spot.
Undervolting your GPU offers benefits with minimal risk. If you encounter issues, you can revert the changes easily. Overall, it’s a safe method to enhance efficiency and cool your graphics card.
Choosing the Right Voltage for Your GPU
Selecting the optimal voltage for your GPU is crucial for performance and efficiency. Experiment with different settings and monitor stability to find the right balance. Consider factors like power consumption and heat management to maximize your GPU’s potential.
How to Undervolt Your GPU Step-by-Step
Undervolting your graphics card is a great way to improve its performance and efficiency. By reducing the power supplied to your GPU, you can lower temperatures which often means your fans won’t have to work as hard. This results in a quieter system and longer component lifespans.
1. Check if Your GPU Supports Undervolting
Not all graphics cards support voltage control, so you’ll first want to check if undervolting is an option for your specific model. Many AMD and NVIDIA cards from the GTX 900 series and up should work. If not, your GPU’s control panel won’t have the necessary voltage settings available.
2. Download a GPU Tuning Utility
Once you’ve verified undervolting is supported, download a third-party tool like MSI Afterburner or EVGA Precision X1. These utilities give you full control over your graphics card’s clock speeds, fan profiles, and voltage.
3. Lower the Voltage in Small Increments
In the utility, you’ll find sliders for core voltage, memory voltage, and possibly auxiliary voltage. Lower each by 10 to 20 millivolts at a time, testing for stability after each change. Most GPUs can handle voltage reductions of 50 millivolts or more, but go slowly to avoid crashing.
4. Test for Stability
After each voltage reduction, run a stress test like Furmark to ensure your GPU remains stable. Look for visual artifacts, driver crashes, or full system lockups which indicate your undervolt is too aggressive. When you start seeing issues, raise voltages back to the last stable values.
5. Save and Automate
Once you’ve found the maximum stable undervolt for your graphics card, save the profile in your tuning utility. This will automatically apply the undervolt each time you boot up for maximum efficiency and performance. Enjoy lower temperatures, quieter fans, and extra performance headroom for overclocking!
Undervolting takes some patience but can provide real benefits. By investing the time to properly test voltages and ensure stability, you’ll have a graphics card that runs cooler, quieter, and often faster for years to come. Let me know if you have any other questions!

Troubleshooting Common GPU Undervolting Issues
Once you’ve undervolted your graphics card, it’s normal to experience a few issues. The good news is most problems are easily fixed.Below are several typical problems you might face and their corresponding solutions.
1. Undervolt Too Aggressive:
If your screen goes black or displays visual artifacts like checkerboard patterns, your undervolt was too aggressive. Reboot your PC and enter the BIOS to reset your graphics card to default values. Then, increase your voltage offset in small increments, testing for stability each time. It’s best to change the voltage in 5-10 mV increments.
2. Games Crash or Freeze:
If games crash or freeze, it usually means your undervolt isn’t 100% stable. Reboot and re-enter the BIOS to reset to default values. When re-undervolting, reduce the amount by 10 mV or so to improve stability. Test again to see if issues persist before making additional changes.
3. Performance Decrease:
Performance decrease is another possible downside of undervolting. If you notice lower frame rates or benchmark scores, your GPU isn’t getting enough power. Reset to default values in the BIOS and undervolt in smaller steps, re-testing performance after each change. Find the “sweet spot” where performance remains the same but temperatures decrease.
4. Impact on Other Components:
Undervolting one component like the GPU can impact the stability of others. If undervolting your GPU causes system instability, undo any undervoltage applied to your CPU or other components. Undervolting multiple parts at once requires a delicate balance.
The key to troubleshooting GPU undervolting is making small changes and testing thoroughly after each adjustment. This helps maintain stability while reducing heat and power use without hurting performance much. If problems persist, switch back to default settings for safety.
