A Graphics Processing Unit (GPU) is the sole component of your computer that does all the graphic rendering tasks you start, like games and animations. The faster the GPU, the better your computer will handle these tasks.
People generally want to overclock their GPU to squeeze out a bit of extra performance. However, underclocking has its unique perks that may attract a specific audience. Underclocking may also solve some prevalent issues regarding the computer.
Today, we’ll discuss everything you need to know about underclocking and how to underclock GPU.
What Is Underclocking?
Underclocking is lowering your GPU’s clock speeds to a lower frequency. On the surface, this might seem like a bad idea since the clock speed defines how fast your GPU can execute tasks at a specific time. But there’s a lot more to it, and underclocking certainly is not for everyone.
Benefits of Underclocking
Underclocking can get some very niche benefits to those who need them. Here’s a few of those –
Reduced Temperatures
Underclocking slows down your GPU, so the machine has to work less and thus generates less energy, which reduces the GPU’s temperatures.
Improved Power Efficiency
Since your GPU gets slowed down and works less, it also requires less power. Essentially, your computer will require less electricity and save some bills.
Reduced Fan Noise
Every GPU has a fan to cool it. The GPU gets hot, the fan speed ramps up, and it may generate some noise. Underclocking the GPU reduces the temps, so the fan doesn’t need to speed up, generating less noise.
Improved Lifespan
All electronic components degrade over time depending on their usage. The more intensely you use it, the faster it will spoil. Underclocking your GPU will ensure it doesn’t always use 100% of its capacity and keep it cool. This significantly improves the lifespan and preserves the quality.
Underclocking Your GPU
GPU underclocking can be done using several methods, but we’ll show you the easiest and most popular way. If done right, it should not harm your computer, and you should safely get your desired results.
Method 1: Using MSI AfterBurner
The MSI AfterBurner is an excellent piece of software that allows you to do all kinds of tweaking and mods to your GPU. The user interface is also quite intuitive and straightforward, and there are many resources about it on the internet.
Aside from underclocking, you can undervolt, overclock, and manage power delivery with MSI AfterBurner.
Step 1: Download and Install MSI AfterBurner
Look up “MSI AfterBurner” on Google. Go to MSI’s official website, download the latest version, and install it. The software has many user interfaces, offering the same functionality and options.
Step 2: Understanding the Interface
Once you open it up, you’ll see many information being displayed and many options. Here’s a brief on what each of them represents,
GPU Clock
This shows the clock speed at which your GPU is currently running.
Mem Clock
It shows the video memory’s current clock speed.
Voltage
Displays the voltage draw of your GPU.
Temp
GPU’s internal temperature.
Core Clock
It lets you control the clock speed of your GPU.
Memory Clock
It allows you to change the speed of your video memory.
There are more options, but you need to know these to underclock.
Step 3: Adjusting the Core Clock
To change the core clock, use the “Core Clock (Mhz) slider.” Moving the slider to the left will decrease the clock speeds, i.e., underclocking your GPU. Depending on your GPU model, you can make some significant adjustments. But how much should you underclock?
Well, that depends on your purpose of underclocking. If your GPU is overheating, a general 50% reduction in speed is a good starting point. Maybe you want to save some power; in that case, you can start at a 30% reduction.
You must experiment with different variations to determine what works for you. And since you are underclocking, you don’t need to worry about breaking your PC.
Step 4: Adjusting the Memory Clock (Optional)
Your video memory is also a part of your GPU, so you might consider underclocking that, too. Although underclocking your memory doesn’t boast as many benefits as underclocking the GPU, it’s worth a try.
To change the memory clock, use the “Memory Clock (Mhz) slider.” Moving the slider to the left will decrease the clock speeds, i.e., underclocking your Video memory.
Step 5: Save Your Settings
Once you are comfortable with your adjustments, click the “save” icon, and you should be done. Close MSI AfterBurner, and your GPU should now be permanently underclocked until you change it.
Method 2: Using AMD Radeon Software
Note: This method will only work if you have an AMD graphics card.
The Radeon software is AMD’s graphics driver utility, which has some essential adjustment tools. It’s not as powerful as MSI AfterBurner, but you don’t have to download anything else, so it’s pretty convenient.
Step 1: Update AMD Graphics Driver to the Latest Version
Go to the AMD control panel from the taskbar and Settings > Check for updates.
Step 2: Change the GPU Clock Speed
Navigate to Performance > Tuning; here, you’ll see the adjustment tools. You’ll find the “Clock Control (Mhz)” slider under the “GPU Tuning” tab. Use the slider to reduce the clock speed to your desired speed.
You can also change the Memory Clock Under the “VRAM Tuning” tab.
Step 3: Save Changes
Once you’re done, press “Apply settings,” and you’re good to go.
Downsides of Underclocking
There are some pretty obvious demerits to underclocking; here’s what you can expect after underclocking –
Extended Start-up Times
Your Windows might take longer to boot up.
Reduced FPS in Games
Games might lag or stutter.
Overall Slower PC
Opening and closing applications might take longer.
Reduced Performance
Your PC might not be able to handle heavy tasks.
Is Underclocking Safe?
Unlike overclocking, underclocking is actually very safe and includes almost no risk. Your PC should be fine if you don’t underclock too much. For safety, keep it at least above 20% of the slider.
On the contrary, underclocking might not be a good idea if you already have a very slow and old PC since the PC’s clock speeds are probably already very low. Lowering that further might make it unusable.
Is Underclocking and Undervolting Same?
No, they are not the same operation. Undervolting means reducing the power input of your GPU while keeping the clock speed the same. It won’t slow down your PC, but reducing the power input will significantly drop the temperature.
Undervolting also includes some risk and requires more expertise.
Conclusion
The trick to efficiently underclock your GPU is by trial and error. Gradually decrease the clock speed till it fits your needs. Don’t be afraid to experiment.
Underclocking is not something everyone wants; the downsides will repel most people. However, if you care more about the benefits, you can try it now since you know how to underclock GPU. We hope this helps.
