Key takeaways
- Reduced Temperatures: Lower voltage means less power consumption, which directly translates to less heat generated by the GPU. This is especially beneficial for compact builds or systems with limited airflow, and can reduce the need for aggressive fan curves.
- Quieter Operation: With lower temperatures, your GPU’s fans don’t need to spin as fast or as often to keep the card cool. This leads to a significantly quieter gaming experience.
- Improved Frame Rates (Potentially): In many cases, high-end GPUs can experience thermal throttling, where they reduce their clock speed to prevent overheating. By undervolting, you can lower temperatures enough to prevent throttling, allowing your GPU to maintain higher clock speeds for longer, thus improving sustained frame rates.
- Increased Longevity: Running components at lower temperatures and with less voltage stress can theoretically contribute to a longer lifespan for your GPU.
- Lower Power Consumption: Less voltage means less power drawn from your PSU, which can be beneficial for power efficiency and can help if you’re nearing the limits of your power supply unit.
What's inside
Are you looking to squeeze more performance and efficiency out of your gaming rig without resorting to a costly hardware upgrade? Undervolting your Graphics Processing Unit (GPU) might be the answer. In 2026, with graphics cards pushing the boundaries of power consumption, undervolting offers a compelling way to reduce heat, lower fan noise, and sometimes even boost frame rates by preventing thermal throttling. This guide will walk you through the process, empowering you to take control of your GPU’s power delivery.
While the concept might sound intimidating, undervolting is a safe and reversible process when done correctly. It involves reducing the voltage supplied to your GPU while maintaining or slightly increasing its clock speed. This results in a more efficient operation, leading to lower temperatures and less strain on your power supply. Let’s dive in.

Understanding Voltage and Clock Speed
Before we begin, it’s crucial to grasp the relationship between voltage and clock speed on your GPU. Clock speed, measured in MHz or GHz, determines how many operations your GPU can perform per second, directly impacting its performance. Voltage, on the other hand, is the electrical pressure that powers these operations. Generally, higher clock speeds require higher voltages to remain stable. Undervolting aims to find the sweet spot: the lowest stable voltage for your desired clock speed.
Why Undervolt Your GPU?
- Reduced Temperatures: Lower voltage means less power consumption, which directly translates to less heat generated by the GPU. This is especially beneficial for compact builds or systems with limited airflow, and can reduce the need for aggressive fan curves.
- Quieter Operation: With lower temperatures, your GPU’s fans don’t need to spin as fast or as often to keep the card cool. This leads to a significantly quieter gaming experience.
- Improved Frame Rates (Potentially): In many cases, high-end GPUs can experience thermal throttling, where they reduce their clock speed to prevent overheating. By undervolting, you can lower temperatures enough to prevent throttling, allowing your GPU to maintain higher clock speeds for longer, thus improving sustained frame rates.

Choosing the Right Software
The most popular and effective tool for undervolting is MSI Afterburner. Despite its name, it’s compatible with GPUs from all manufacturers (NVIDIA and AMD). It provides a user-friendly interface to adjust core voltage, clock speeds, and fan curves. For AMD users, AMD’s Adrenalin Software also offers built-in performance tuning options that include voltage adjustments.
Key features in MSI Afterburner:
- Core Voltage Slider: This is the primary control for undervolting. You’ll be decreasing this value.
- Core Clock Offset: Allows you to adjust the GPU’s core clock speed. We’ll often try to maintain or slightly increase this while lowering voltage.
- Memory Clock Offset: Adjusts the GPU’s memory clock speed. Generally, memory is less sensitive to voltage changes, so you might be able to slightly increase this for a minor performance boost.
- Fan Speed Control: Essential for monitoring and adjusting fan curves to optimize cooling.
The Undervolting Process: Step-by-Step
The undervolting process is iterative and requires patience. Here’s a general approach:
- Install and Open MSI Afterburner: Download the latest version of MSI Afterburner and install it. Launch the application.
- Unlock Voltage Control: In MSI Afterburner’s settings (gear icon), ensure “Unlock voltage control” and “Unlock voltage monitoring” are enabled. You may need to select a specific control mode depending on your GPU.
- Set a Custom Fan Curve: Before touching voltage, go to the fan settings and set up a more aggressive fan curve. This ensures your GPU stays cool during testing. A common starting point is 70-80% fan speed at 70-80°C.
- Find Your Starting Point: Note down your GPU’s default core voltage and clock speed in a demanding game or benchmark.
- Start Lowering Voltage: Begin by reducing the core voltage slider in small increments, perhaps by 10-25mV at a time.
- Test Stability: After each voltage adjustment, run a demanding benchmark (like Heaven, Superposition, or 3DMark) or play a graphics-intensive game for at least 15-30 minutes. Monitor for any crashes, artifacts (visual glitches), or driver errors.
- Adjust Clock Speed (Optional but Recommended): If your system is stable at a lower voltage, you can try to increase the core clock speed slightly (e.g., +25MHz or +50MHz) and re-test for stability. This is how you can sometimes achieve better performance than stock.
- Repeat and Refine: Continue this process of lowering voltage and testing, then potentially increasing clock speed. You’re looking for the lowest stable voltage that allows your GPU to run at your desired clock speed without issues.
- Save Your Profile: Once you find a stable setting, click the “Apply” button (checkmark icon) and then click the save icon to store your profile. You can then set it to apply on startup.
Tips for Successful Undervolting
- Patience is Key: Undervolting is not a quick process. Take your time, test thoroughly, and don’t rush.
- Test with Multiple Applications: A setting that’s stable in one game might not be stable in another. Test with a variety of your most demanding titles.
- Monitor Temperatures Closely: Use MSI Afterburner’s on-screen display or other monitoring tools to keep an eye on your GPU temperatures throughout your testing. Aim to keep them below 80°C under load.
- Consider a GPU Support Bracket: While not directly related to undervolting, ensuring your GPU is properly supported can prevent physical stress, especially for larger cards. Products like the acer GPU Support Bracket, California JOS GPU Support Bracket, and generic Graphics Card GPU Brace Support can help mitigate sag. For vertical mounting, consider options like the Lian Li ATX PC Case 4 Slots Vertical GPU Kit.
Frequently Asked Questions
What is thermal throttling?
Thermal throttling occurs when a component, like your GPU, reaches a critical temperature. To prevent damage, it automatically reduces its clock speed and performance to lower its temperature. Undervolting helps prevent this by reducing heat generation.
Is undervolting safe for my GPU?
Yes, when done correctly, undervolting is safe. You are reducing the voltage, not increasing it, which is the primary concern for hardware damage. The worst that can happen from an unstable undervolt is a system crash or driver error, which is easily rectified by resetting to default settings.
What is a stable undervolt?
A stable undervolt is a voltage setting that allows your GPU to run at your desired clock speeds without experiencing crashes, artifacts, or other performance issues in any of your typical gaming or demanding applications.
Can I undervolt my ASUS NVIDIA GeForce RTX™ 5060 LP?
Yes, the process described using MSI Afterburner is applicable to most modern GPUs, including specific models like the ASUS NVIDIA GeForce RTX™ 5060 LP, provided the software supports voltage control for that particular card and architecture.
Conclusion
Undervolting your GPU is a powerful technique for improving your gaming experience without spending extra money. By carefully reducing voltage, you can achieve lower temperatures, quieter operation, and potentially even better performance. Remember to approach the process systematically, test thoroughly, and always prioritize stability. With a little patience, you’ll be enjoying a cooler, quieter, and more efficient gaming rig in no time.
