Does Undervolting Your CPU Increase FPS?

Many gamers chase the holy grail of smooth gameplay: high frames per second (FPS). One strategy that gets thrown around is undervolting the CPU. But does this tweak actually boost your FPS, or is it more about keeping things cool? In this article, we’ll dive into the world of undervolting and explore its impact on FPS, thermals, and overall system stability.

What is FPS and Why Does It Matter?

Imagine a movie. It’s a series of still images shown rapidly to create the illusion of movement. Similarly, in video games, your graphics card renders frames (images) one by one, and the faster these frames are displayed on your screen, the smoother the gameplay feels. FPS is a measure of how many frames are displayed per second. Higher FPS translates to smoother visuals, quicker response times, and a more competitive edge.

Undervolting Explained

Your CPU, the brain of your computer, performs calculations at incredible speeds. To achieve this, it requires a specific amount of electricity, measured in volts. Undervolting essentially reduces the voltage supplied to the CPU. This approach aims to achieve two primary goals: lower heat generation and reduced power consumption.

Think of it like this: imagine a car engine. The more fuel (voltage) it gets, the faster it goes (higher clock speed), but it also generates more heat. Undervolting is like adjusting the fuel mixture for optimal performance – you want enough power for smooth running, but not so much that it overheats and sputters.

So, Does Undervolting Your CPU Directly Increase FPS? 

Here’s the key takeaway: undervolting typically doesn’t directly translate to a significant FPS boost. In fact, if not done correctly, reducing voltage can lead to instability, causing crashes or glitches that hinder your gameplay even more.

The Indirect Advantage: Avoiding Thermal Throttling

By undervolting, you can potentially reduce the heat generated by your CPU

However, undervolting can indirectly improve FPS in specific scenarios. Here’s why: when your CPU gets too hot, it activates a safety mechanism called thermal throttling. This essentially slows down the CPU to prevent overheating damage. This throttling can lead to noticeable performance dips, especially during demanding gaming sessions.

By undervolting, you can potentially reduce the heat generated by your CPU. This keeps it cooler and allows it to maintain its normal clock speeds for longer periods, potentially preventing thermal throttling and maintaining consistent FPS throughout your gameplay.

Additional Benefits of Undervolting

While the FPS boost might be indirect, undervolting offers other attractive benefits for gamers.

  • Lower Power Consumption: By reducing the voltage, you’re essentially using less electricity to power your CPU. This translates to lower energy bills and less strain on your power supply unit (PSU).
  • Quieter Operation: Less heat means less fan noise. Undervolting can lead to a quieter overall system, making your gaming sessions more peaceful.

Important Considerations Before You Undervolt

Undervolting isn’t a magic bullet. Here are some crucial points to consider.

  • Technical Knowledge Required: Undervolting involves tweaking BIOS settings or using specialized software. It requires some technical know-how and a willingness to experiment cautiously.
  • Not All CPUs Are Created Equal: Not all CPUs are designed for undervolting. It’s essential to check if your specific CPU model supports undervolting and research recommended voltage adjustments.
  • Stability is Key: The key to successful undervolting is finding the sweet spot where you achieve lower voltage without sacrificing stability. Stress testing your system after undervolting is crucial to ensure everything runs smoothly.

Final Thougths

Undervolting doesn’t guarantee a direct FPS boost, but it can be a valuable tool for gamers experiencing thermal throttling. In those situations, undervolting can help your CPU maintain its performance by keeping it cooler. Additionally, the benefits of lower power consumption and quieter operation make it an attractive option for many gamers.

However, remember that undervolting requires some technical knowledge and carries the risk of instability. It’s best to consult online guides and benchmark results specific to your CPU model before diving in. By carefully undervolting, you can potentially fine-tune your system for cooler operation, extended performance during gameplay, and a more efficient overall gaming experience.


Q. Will undervolting void my CPU warranty?
A. Undervolting practices generally don’t void warranties. However, it’s always best to consult your CPU manufacturer’s warranty policy for specific details.

Q. What tools do I need to undervolt my CPU?
A. The specific tools depend on your CPU model.

Q. Are there any risks to undervolting besides instability?
A. While uncommon, undervolting too aggressively can potentially shorten the lifespan of your CPU in the long run. However, the risks are generally considered minimal if you stay within safe voltage ranges recommended for your specific CPU model.

Q. How much FPS improvement can I expect from undervolting?
A. Unfortunately, there’s no one-size-fits-all answer. The potential FPS gains depend on several factors, including your specific CPU, cooling solution, and the games you play. In most cases, the improvement might be negligible. The primary benefit lies in preventing thermal throttling and maintaining consistent performance.

Q. Is undervolting worth it for casual gamers?
A. For casual gamers who don’t experience thermal throttling issues, the benefits of undervolting might be less noticeable. However, it can still be a worthwhile option for those who prioritize a quieter system or lower power consumption.
