Though overclocking is the most common alternative, you may want to underclock your GPU in some instances. Underclocking on graphics card processor GPUs is performed commonly to decrease heat output. For example, when doing everyday activities (such as internet searching and word processing), a GPU may be set to run at lower clock rates, allowing the card to work at lower and fewer and slower fans' speeds.

For more graphically intensive uses like games, the GPU may also be overclocked.

Undertaking a GPU reduces efficiency, but this decrease is not likely to be visible except in graphic intensity applications.

For modern CPUs, the same is true: When a single-core Intel CPU was underclocked by 20%, the PC's output dropped by just 13%, while its power consumption dropped by 49%. A CPU with a capacitance C and a frequency f and voltage V consume almost the same amount of power in general.

What we can expect?

  • Reduced heat output, which is proportional to the amount of energy used.
  • Since the cooling fans may be slowed or even turned off, there would be less noise.
  • The efficiency of a cooling fan is equal to its rotation speed, but as the rotation speed increases, so makes the noise.
  • With Hardware that lasts more extended, Stability has improved.
  • Battery life has been extended.
  • Improved consistency with legacy software.
  • The proper output of ancient video games that were timed by the CPU.

Do You Need to Underclock Your GPU?

To get a speed boost, most gamers overclock their machine (both CPU and GPU). Underclocking the GPU essentially reduces the clock speeds. Underclocking your GPU is perfect if you use your machine to surf the internet or play light games. This should result in lower energy costs while maintaining the same level of efficiency. People like to underclock their graphics cards for a variety of reasons. The summer season is a wonderful time to do underclocking if you live in a Western country. Temperatures could reach 5C-10C during this time of year. Another aspect that contributes to a rise in temperature is poorly optimized airflow. It's even likely that the thermal paste has to be replaced.

Benefits of Underclocking GPUs

It's essential to understand the advantages of underclocking your GPU before finding out how to do it. There are four big bonuses for someone who underclocks their GPU in total.

• Reduced Power Consumption When you lower the clock speed on your machine, it means your hardware is using less power to run. You can save money on the utility bills as a result of the decreased power demand.

• Lowered Temperature Lowering the clock speed would, once again, result in lower fan speeds. As a result, the GPU can now operate at a lower temperature, making it much more incredible. This is relevant because most electronic equipment is typically susceptible to and degraded by heat.

• Fans with less noise Things may be starting to sound a little stale at this stage. This is because underclocking has so many advantages, all of which are interconnected. The more the GPU's temperature goes up, the faster the fans must spin to keep it cold. This amplifies their volume. As you might be aware, clock speed causes the temperature to increase, but underclocking allows fans to operate slower and, therefore, quieter pace.

• Reduced risk of overheating Your fans are now quieter and don't have to work too hard, your power demand is lower, and your GPU runs at a more relaxed pressure than before. As a result, the risks of machine overheating have now significantly been minimized.

How to Underclock GPU Using Software?

You can finish the task with the help of some tech. EVGA Precision XOC, NZXT Cam, and ASUS GPU Tweak are some of the new choices. MSI Afterburner, on the other hand, is the most common and most people's choices go-to. This is also the one we'll be talking about. As a result, if you want to learn how to underclock your AMD GPU or your NVIDIA GPU, you'll need to learn how to use Afterburner first. Fortunately, it's an easy method.

What is MSI Afterburner, and how does it work?

Afterburner allows you to tweak your GPU's voltage, heat, core clock rate, and memory clock speed. It has an incredibly user-friendly layout.

Getting things in order: Of course, the first move is to download the app. MSI Afterburner is available for free here. Once you've downloaded it, go to the configuration wizard and set it up, much like every other piece of software. Until continuing, double-check that the graphics card is being identified.

Adjusting Central Clock: Open the utility until it is in place. Many of your customizable settings can be found in the middle of your screen. The Central Clock Meter, for example, displays the GPU's clock speed in MHz. You can change the clock speed by sliding this meter to the left to slow it down, which is just what we need in this situation, or vice versa.

For Added Benefit, Undervolting: To get the best out of their setup, certain users like to mix undervolting and underclocking. By design, most GPUs are set to higher voltages, but they don't need as much voltage to operate once underclocked. As a result, undervolting will enhance the advantages that underclocking already provides. If you like to undervolt, there are a few things to worry about:

• While all work well together, undervolting has lower output costs than underclocking. • The majority of cards would only allow you to make changes in multiples. • If you want to undervolt your processor, set the Core Voltage Meter in the same way you did the clock speed.

Saving Changes:

When you're pleased with the clock speed and voltage you've picked, press the checkmark to save and add the adjustments.

Checking for Stability:

Both of these improvements can ideally assist you in obtaining the advantages mentioned above. We all know that underclocking makes a GPU run more relaxed, but what if your GPU isn't cooling off as it is supposed to?

After you've made the improvements, you'll need a way to track your success so you can figure out what else needs to be done. Setting up a custom fan curve is the easiest way to do this. Fan curves show the relationship between fan speed and temperature, so this is optimal. To do so, press the settings icon underneath the fan speed meter to go to the fan page.

It would be perfect if you experimented with the settings to see what ratio works well for you. Finally, remember to put your GPU to the test. Stress tests can be used to see how well the GPU and rig do in extreme conditions. When stress checking, underclocking your GPU can result in a lot more reliability and lower temperatures.
