How To Undervolt GPU With MSI Afterburner ?

Are you looking for a comprehensive guide on How to undervolt GPU with MSI Afterburner? In this article, we will discuss everything you need to know about undervolting. We’ll cover what it is, why you might want to do it, and how to go about doing it safely. Plus, we’ll provide a step-by-step guide on how to undervolt your GPU with MSI Afterburner. So whether you’re a beginner or an experienced overclocker, this article has something for you.

what is undervolting?

In short, undervolting is the process of reducing the voltage that your GPU receives. This can be done for a number of reasons, but the most common one is to reduce power consumption. By reducing the voltage, you can also reduce the amount of heat that your GPU produces. And in some cases, you might even be able to achieve a higher clock speed while using less power. Of course, there are some risks involved in undervolting your GPU.

But if you do it correctly, undervolting can be a safe and easy way to improve your GPU’s performance. So without further ado, let’s get started!

If you don’t know what you’re doing, it’s possible to damage your GPU. That’s why we recommend that you only undervolt your GPU if you’re confident in your abilities and you know what you’re doing.

How To Undervolt GPU With MSI Afterburner ?

With that being said, let’s take a look at how to undervolt your GPU with MSI Afterburner. The first thing you’ll need to do is download MSI Afterburner. This is a free program that allows you to overclock your GPU and monitor it.

Step 1: Start the Heaven Benchmark Up

Open the benchmark with the default settings in windowed mode. The GPU’s maximum stable core clock speed can be reached while using graphics-intensive applications such as games when running the benchmark in windowed mode.

Step 2: Open MSI Afterburner Utility

Pay attention to the GPU clock speed right at the top of MSI Afterburner GPU overclocking software. In our case, the NVIDIA RTX 3070 stayed at a core clock speed of 1905MHz. Make a note of the clock speed your GPU reaches after 10 to 15 minutes of operation.

Step 3: Examine the Voltage/Frequency Curve

What Is GPU Undervolting?

To access the Curve Editor, open MSI Afterburner and press CTRL + F. Make a note of the GPU core clock frequency (vertical or Y-axis values) where the curve ends on the right side of the screen, as it has been highlighted in red in the following screenshot.

In the example above, the curve reaches a maximum of 1950MHz between voltages ranging from 1150mV to 1250mV. For the most part, modern NVIDIA GPUs function best at a frequency of 1800MHz. Our goal is to alter the frequency/voltage curve so that it peaks at 1800MHz, as shown by the green line.

Step 4: Reduce GPU Core Clock Speed to the Calculated Value

Enter the theoretical speed in the Core Clock area of the MSI Afterburner main program and hit the Enter key. The GPU core clock frequency curve should be lowered to 1800MHz in this case.

Step 5: Set the GPU Voltage Threshold for Max Performance

The goal of our GPU voltage reduction is to maintain system stability while still lowering the GPU voltage. NVIDIA RTX 3070 maximums out at 1085mV in the figure above. You should be able to run it at a significantly lower voltage without any problems depending on the quality of the chip on your graphics card.

It’s best to begin by setting your ASIC miner’s initial voltage at 950mV and checking the system for stability before increasing the GPU operational voltage any further. We elected to start things off by reducing GPU voltage to 900mV.

Step 6: Set the New Voltage Curve

To apply the new voltage curve, click the checkmark button in the MSI Afterburner main window. Beyond 900mV, the frequency/voltage curve will become flat.

You may also check this by changing the Curve readout to show instead of GPU clock frequency offset (highlighted in green).

Step 7: Testing GPU for Stability

The easiest method to confirm the GPU undervolt is to perform a graphics card-specific stress test with a low tolerance for system instability. The 3D Mark Time Spy Extreme benchmark is ideal for this purpose. While it runs, pay attention to graphical anomalies.

If your GPU is unable to obtain enough power, you’ll either see graphical problems or the benchmark will fail. In the worst-case scenario, your operating system might crash, but your hardware will not be damaged.

If you’ve run into any problems, repeat Step 5 while raising the voltage value by 25mV each time. For example, if 900mV caused system instability or graphical problems, we would raise our GPU voltage to 925mV.

How To Undervolt GPU Without Afterburner?

There are a few ways to do this. One is to use the built-in NVIDIA Control Panel to lower the power target. Another option is to use a tool like MSI Afterburner, which gives you more granular control over your card’s settings. Finally, you could also try using a command-line tool like NVFlash or Wattman. Each of these methods has its own set of pros and cons, so you’ll need to decide which one is best for you.

To undervolt your GPU using the NVIDIA Control Panel:

-Open the Nvidia Control Panel

-Click on “Manage settings”

-Select “Power management mode”

-Select “Prefer maximum performance”

This will prevent your card from dropping down to its minimum frequency, which can help you achieve a higher overclock.


Please note that while overclocking and undervolting can help improve your system’s performance, there is always a risk of damaging your hardware. Please proceed with caution and at your own risk.
