How to Underclock GPU – The Ultimate Guide

Underclocking your GPU is an often overlooked method of optimizing your computer’s performance and power efficiency. While most people are familiar with overclocking to boost gaming or productivity performance, underclocking can offer benefits like lower temperatures, quieter fan noise, and reduced power consumption. If you’re looking to extend the lifespan of your hardware, prevent overheating, or simply make your system run quieter, underclocking can be a great option. This guide will walk you through everything you need to know about how to underclock GPU, the benefits and risks, and step-by-step instructions to get you started.

What explains Underclocking a GPU?

Underclocking a GPU means lowering its clock speeds—both the core clock and memory clock speeds. By reducing these frequencies, you decrease the workload on your GPU, resulting in lower power usage, less heat generation, and quieter operation. Underclocking doesn’t harm the GPU if done properly, unlike overclocking, which can sometimes cause instability or hardware damage if done incorrectly.

What would you need to Underclock Your GPU?

There are several reasons you might want to underclock your GPU, including:

1. Lower Power Consumption: Reducing the clock speeds helps lower the power draw, which can save you money on electricity and extend battery life in laptops.
2. Reduced Heat Output: Less power means less heat, which is beneficial for maintaining lower temperatures and preventing your GPU from overheating.
3. Quieter Performance: GPUs often have fans that spin faster when the card is under heavy load, producing more noise. Underclocking reduces the load, keeping fans quieter.
4. Increase Hardware Lifespan: Lower temperatures and reduced wear from constant high usage can help extend the lifespan of your GPU.
5. Stable Performance for Non-Gaming Tasks: If you’re using your computer for less demanding tasks like web browsing, video streaming, or office work, underclocking your GPU can improve system stability and responsiveness.

What is the way to Underclock Your GPU? A Step-by-Step Guide

Before we begin, it’s important to note that underclocking requires caution. You should always ensure that your GPU is still capable of handling your normal tasks and games even after the changes.

Step 1: Gather the Necessary Tools

To underclock your GPU, you’ll need a GPU tuning tool. Here are some popular options:

1. MSI Afterburner: One of the most popular and widely used tools for overclocking and underclocking GPUs.
2. EVGA Precision X1: Another popular tool for managing GPU performance.
3. GPU-Z: A useful tool for monitoring GPU stats in real-time.
4. AMD Radeon Software or Nvidia GeForce Experience: Built-in software from AMD and Nvidia that can help you adjust clock speeds.

These tools will allow you to adjust the core clock, memory clock, voltage, and fan speeds of your GPU.

Step 2: Install GPU Monitoring Software

Before making any changes, it’s important to monitor the temperature and performance of your GPU. Download software like GPU-Z or MSI Afterburner to check your current GPU load, temperature, clock speeds, and fan speeds.

Step 3: Determine the Desired Clock Speeds

Once your monitoring software is installed, you’ll want to know the default clock speeds for your GPU. You can find this information in the official documentation from the manufacturer or by using GPU-Z. From here, you can determine how much you want to lower the clock speeds.

• Core Clock: This refers to the speed at which the GPU processes tasks.
• Memory Clock: This controls the speed of the VRAM on the GPU.

A good starting point for underclocking is to reduce the core clock and memory clock by 10-20%. For example, if your GPU’s core clock is set at 1500 MHz, you could try reducing it to 1300-1400 MHz.

Step 4: Make the Changes in Your Tuning Software

Once you’ve decided on the amount you want to reduce, it’s time to open your GPU tuning software and start making adjustments.

In MSI Afterburner:

1. Open MSI Afterburner.
2. Locate the Core Clock and Memory Clock sliders.
3. Move the sliders to reduce the clock speeds by your chosen amount.
4. Click Apply to save the changes.

In EVGA Precision X1:

1. Open the EVGA Precision X1 software.
2. Adjust the GPU Clock and Memory Clock sliders to your desired values.
3. Press Apply to set the new clock speeds.

Step 5: Test the Stability

After underclocking, it’s crucial to test your GPU to ensure it is stable and running properly. You can use tools like FurMark or Unigine Heaven to stress-test your GPU and make sure it doesn’t crash or show signs of instability.

If you experience crashes, glitches, or artifacts, it might indicate that the clock speeds were reduced too much. In that case, go back to the tuning software and slightly increase the clock speeds until the system becomes stable again.

Step 6: Monitor the Results

After underclocking and stress-testing your GPU, monitor the performance and temperature for a few hours or days to ensure everything is working as expected. You should notice lower power usage, quieter performance, and reduced heat output.

Pros and Cons of Underclocking Your GPU

Pros:

1. Reduced Heat: Underclocking will significantly lower the temperature of your GPU, helping to prevent thermal throttling.
2. Lower Power Usage: This can be beneficial for those who want to save on electricity, or who are using laptops and want to increase battery life.
3. Quieter Operation: Reducing the clock speeds can result in less fan noise, making your system quieter during regular tasks.
4. Extended Hardware Lifespan: Lower heat and reduced power usage can extend the lifespan of your GPU by reducing wear and tear on the hardware.

Cons:

1. Potential Performance Hit: While underclocking can lower power consumption, it may also result in slower performance in GPU-intensive tasks like gaming or 3D rendering.
2. Stability Issues: If you underclock too much, your system may become unstable, which could result in crashes or graphical glitches.
3. Limited Gains in Some Cases: In certain scenarios, underclocking may not yield substantial power savings or temperature reductions, especially if the GPU is already idle most of the time.

FAQs

1. Is it safe to underclock my GPU?

Yes, underclocking is generally safe if done properly. It reduces the workload on the GPU, which helps reduce heat and power usage without risking damage to the hardware.

2. How much can I safely underclock my GPU?

A safe starting point is to reduce both the core and memory clock speeds by 10-20%. You can always fine-tune based on your results.

3. Will underclocking my GPU improve my FPS in games?

Underclocking is more about reducing power usage and heat than boosting performance. If you’re gaming, underclocking might reduce your FPS, as it lowers the GPU’s processing power.

6. What is the difference between underclocking and overclocking?

Underclocking lowers the clock speeds to reduce power usage and heat, while overclocking increases clock speeds to boost performance.

7. Can underclocking improve power efficiency on a laptop?

Yes, underclocking your GPU on a laptop can help increase battery life by reducing power consumption.
