How to underclock the computer with software, instead of BIOS

Underclocking your computer can be a useful technique to reduce power consumption and heat generation, especially if you have an older or less powerful system. While it’s possible to underclock your computer through the BIOS settings, not all motherboards support this feature. Fortunately, there are several software tools available that can help you underclock your computer without having to access the BIOS.

Here are some steps you can follow to underclock your computer using software:

1. Download and install a software tool that can help you underclock your computer. Some popular options include MSI Afterburner, EVGA Precision X1, and AMD Radeon Software.

2. Once you’ve installed the software, open it up and look for the option to adjust clock speeds. This may be labeled differently depending on the software you’re using, but it should be fairly easy to find.

3. Adjust the clock speeds to a lower value than the default. This will vary depending on your system, but a good starting point is to reduce the clock speed by around 10-20%.

4. Test your system to make sure it’s stable at the new clock speed. You can do this by running a stress test or benchmarking tool, such as Prime95 or FurMark. If your system crashes or experiences other issues, you may need to adjust the clock speed further.

5. Once you’ve found a stable clock speed, save your settings and exit the software. Your computer should now be underclocked and running at a lower speed than before.

It’s worth noting that underclocking your computer can have some downsides, such as reduced performance in certain applications. However, if you’re looking to reduce power consumption or heat generation, it can be a useful technique to try. Just be sure to monitor your system carefully and adjust the clock speeds as needed to ensure stability.


In conclusion, underclocking your computer using software can be a great way to reduce power consumption and heat generation, especially if your motherboard doesn’t support this feature in the BIOS. Just be sure to use a reliable software tool and test your system carefully to ensure stability. And remember, while underclocking can have some downsides, it can also be a useful technique to try if you’re looking to optimize your system’s performance.
