What is Undervolting?<\/strong>\u00a0<\/h2>\n\n\n\nUndervolting is an alternative to overclocking. When you undervolt, you are reducing the overall voltage that your component receives from the PSU. This will help to generate less heat resulting in quieter operation and reduced power consumption<\/a>. <\/p>\n\n\n\nYou can undervolt a variety of components, including the CPU, GPU, and RAM. <\/p>\n\n\n\n

\n\n\n\nHow to Undervolt a CPU: Step-by-Step<\/strong>\u00a0<\/h2>\n\n\n\nIf you\u2019re looking to undervolt your CPU but don\u2019t know where to start, we\u2019ve broken it down step-by-step below.\u00a0\u00a0<\/p>\n\n\n\n
What You Need<\/strong>\u00a0<\/h3>\n\n\n\nBefore you begin, you\u2019ll first need to ensure you\u2019ve got the right tools. This includes: <\/p>\n\n\n\n
\n- Your PC with a stable internet connection\u00a0<\/li>\n<\/ul>\n\n\n\n
\n- A dedicated undervolting software such as Throttlestop or AMD Ryzen Master\u00a0<\/li>\n<\/ul>\n\n\n\n
\n- Benchmarking software such as CPU-Z, 3DMark, or Cinebench\u00a0<\/li>\n<\/ul>\n\n\n\n
\n- Temperature and voltage monitoring software such as HWMonitor or Open Hardware Monitor\u00a0<\/li>\n<\/ul>\n\n\n\n
How to Undervolt<\/strong>\u00a0<\/h3>\n\n\n\nYou\u2019ll first need to download all the necessary software. In our example, we\u2019ll be using CPU-Z to benchmark and test our processor, HWMonitor to keep track of temperatures, and Throttlestop to undervolt. <\/p>\n\n\n\n
Once all your software is downloaded, open them all up and run the CPU-Z benchmark whilst monitoring performance via HWMonitor. Here, you\u2019ll want to take note of the temperature of your cores and the maximum voltage that they reach during the benchmark. We recommend you make a physical note of these as this will serve as your starting point, so you don\u2019t want to forget them! <\/p>\n\n\n\n
From here, open up Throttlestop*<\/strong>. You may be presented with a warning pop-up about the software making significant changes to your CPU. This is true, so if you are comfortable with this, press OK to proceed. <\/p>\n\n\n\nIn the main Throttlestop window, locate Speed Shift \u2013 EPP<\/strong>. This should be on the left side. Tick this option. This will enable the Speed Shift technology, otherwise known as Hardware Controlled Performance, which is responsible for improving performance and responsiveness by enabling the CPU to automatically switch to the best voltage\/frequency depending on your workload. <\/p>\n\n\n\n![\"\"](\"https:\/\/www.overclockers.co.uk\/blog\/wp-content\/uploads\/2023\/08\/Anatomy-of-a-CPU-Blank-Overclockers-UK-Blog-Feature-Image-Bottom-Text-Blog-1600x900Light-TextTwitter--1024x576.jpg\")
<\/figure>\n\n\n\nFrom here, select the setting called FIVR. This will open up a new window and might look rather scary as it\u2019ll be a huge overview of various settings. <\/p>\n\n\n\n
In the FIVR Control<\/strong> column, make sure the following options are ticked; <\/p>\n\n\n\n\n- CPU Core\u00a0<\/li>\n<\/ul>\n\n\n\n
\n- CPU Core Voltage\u00a0<\/li>\n<\/ul>\n\n\n\n
\n- Unlock Adjustable Voltage\u00a0<\/li>\n<\/ul>\n\n\n\n
To undervolt your processor, you\u2019ll need to adjust the Offset Voltage<\/strong>. You should do this in small increments to help you find that sweet spot. The final amount all depends on your processor. Older CPUs can struggle with big undervolts while modern-day processors, such as Alder Lake, can handle this bigger power adjustment. <\/p>\n\n\n\nStart by tweaking the millivolt (mV)<\/strong> value by a larger amount. What you pick depends on your chip, but \u201350mV<\/strong> is a safe starting point. If your PC continues to function correctly, you can go back and lower the voltage a little bit more. <\/p>\n\n\n\n![\"Pile](\"https:\/\/www.overclockers.co.uk\/blog\/wp-content\/uploads\/2024\/07\/cpus-1024x576.png\")
<\/figure>\n\n\n\nOnce you\u2019ve adjusted the Offset Voltage<\/strong>, switch your selection in the FIVR Control <\/strong>column to CPU Cache<\/strong> <\/em><\/strong>and tweak the undervolt to be the same value as the CPU Core. From here, select Intel GPU<\/strong> and undervolt this slightly. This step is entirely optional but anywhere between 25-50m<\/strong>V is safe. It\u2019s fine to skip this step, especially if you experience stability issues later as it\u2019s not essential for tweaking your temperatures and voltages. <\/p>\n\n\n\nIf you\u2019re happy with everything, press Apply<\/strong>. Your PC may immediately crash, but don\u2019t worry! If this happens, you need to go back, adjust your voltage settings, and go a little easier this time. You may also need to select OK<\/strong> > Save Voltage Immediately <\/strong>> Apply<\/strong>. <\/p>\n\n\n\nNow it\u2019s time for you to put your voltages to the test by running the CPU-Z benchmark and monitor the temperatures\/voltages in HWMonitor. Compare the values to the ones achieved before you undervolted. You should hopefully see an improvement. <\/p>\n\n\n\n![\"\"](\"https:\/\/www.overclockers.co.uk\/blog\/wp-content\/uploads\/2023\/01\/amd-ryzen-cpu.jpg\")
<\/figure>\n\n\n\nIf your PC doesn\u2019t crash, we recommend you perform a few extra tests just to make sure everything is fine. Ideally, you should really put your PC to the test by running every application that you usually would, any games, Discord, Chrome tabs, etc. The trick here is to really stress your PC to check for any instabilities caused by undervolting. <\/p>\n\n\n\n
If your PC doesn\u2019t crash and you\u2019re happy with the results, you\u2019ve successfully undervolted your CPU! However, if not, you can go back and repeat the steps listed above but start with smaller 5-10mV<\/strong> increments. <\/p>\n\n\n\n*Throttlestop mainly works for Intel CPUs. If you are trying to undervolt an AMD processor and Throttlestop isn\u2019t working, try AMD Ryzen Master.\u00a0<\/strong>\u00a0<\/p>\n\n\n\n
\n\n\n\nHave You Tried Everything?\u00a0<\/strong>\u00a0<\/h2>\n\n\n\nAre you still struggling with excess temperatures and unstable performance even after undervolting your CPU? There are still a few more things you can try before you give up! This includes trying a new CPU cooler or even reapplying your thermal paste.\u00a0Don\u2019t know how to go about applying some new thermal paste? We\u2019ve got a blog post for that.<\/a>\u00a0<\/p>\n\n\n\nIf all else fails, it might simply be time to treat yourself to an upgrade. <\/p>\n\n\n\n

We recommend you make a physical note of these as this will serve as your starting point, so you don\u2019t want to forget them! <\/p>\n\n\n\n
From here, open up Throttlestop*<\/strong>. You may be presented with a warning pop-up about the software making significant changes to your CPU. This is true, so if you are comfortable with this, press OK to proceed. <\/p>\n\n\n\nIn the main Throttlestop window, locate Speed Shift \u2013 EPP<\/strong>. This should be on the left side. Tick this option. This will enable the Speed Shift technology, otherwise known as Hardware Controlled Performance, which is responsible for improving performance and responsiveness by enabling the CPU to automatically switch to the best voltage\/frequency depending on your workload. <\/p>\n\n\n\n<\/figure>\n\n\n\nFrom here, select the setting called FIVR. This will open up a new window and might look rather scary as it\u2019ll be a huge overview of various settings. <\/p>\n\n\n\n
In the FIVR Control<\/strong> column, make sure the following options are ticked; <\/p>\n\n\n\n\n- CPU Core\u00a0<\/li>\n<\/ul>\n\n\n\n
\n- CPU Core Voltage\u00a0<\/li>\n<\/ul>\n\n\n\n
\n- Unlock Adjustable Voltage\u00a0<\/li>\n<\/ul>\n\n\n\n
To undervolt your processor, you\u2019ll need to adjust the Offset Voltage<\/strong>. You should do this in small increments to help you find that sweet spot. The final amount all depends on your processor. Older CPUs can struggle with big undervolts while modern-day processors, such as Alder Lake, can handle this bigger power adjustment. <\/p>\n\n\n\nStart by tweaking the millivolt (mV)<\/strong> value by a larger amount. What you pick depends on your chip, but \u201350mV<\/strong> is a safe starting point. If your PC continues to function correctly, you can go back and lower the voltage a little bit more. <\/p>\n\n\n\n<\/figure>\n\n\n\nOnce you\u2019ve adjusted the Offset Voltage<\/strong>, switch your selection in the FIVR Control <\/strong>column to CPU Cache<\/strong> <\/em><\/strong>and tweak the undervolt to be the same value as the CPU Core. From here, select Intel GPU<\/strong> and undervolt this slightly. This step is entirely optional but anywhere between 25-50m<\/strong>V is safe. It\u2019s fine to skip this step, especially if you experience stability issues later as it\u2019s not essential for tweaking your temperatures and voltages. <\/p>\n\n\n\nIf you\u2019re happy with everything, press Apply<\/strong>. Your PC may immediately crash, but don\u2019t worry! If this happens, you need to go back, adjust your voltage settings, and go a little easier this time. You may also need to select OK<\/strong> > Save Voltage Immediately <\/strong>> Apply<\/strong>. <\/p>\n\n\n\nNow it\u2019s time for you to put your voltages to the test by running the CPU-Z benchmark and monitor the temperatures\/voltages in HWMonitor. Compare the values to the ones achieved before you undervolted. You should hopefully see an improvement. <\/p>\n\n\n\n<\/figure>\n\n\n\nIf your PC doesn\u2019t crash, we recommend you perform a few extra tests just to make sure everything is fine. Ideally, you should really put your PC to the test by running every application that you usually would, any games, Discord, Chrome tabs, etc. The trick here is to really stress your PC to check for any instabilities caused by undervolting. <\/p>\n\n\n\n
If your PC doesn\u2019t crash and you\u2019re happy with the results, you\u2019ve successfully undervolted your CPU! However, if not, you can go back and repeat the steps listed above but start with smaller 5-10mV<\/strong> increments. <\/p>\n\n\n\n*Throttlestop mainly works for Intel CPUs.

What You Need<\/strong>\u00a0<\/h3>\n\n\n\nBefore you begin, you\u2019ll first need to ensure you\u2019ve got the right tools. This includes: <\/p>\n\n\n\n
\n- Your PC with a stable internet connection\u00a0<\/li>\n<\/ul>\n\n\n\n
\n- A dedicated undervolting software such as Throttlestop or AMD Ryzen Master\u00a0<\/li>\n<\/ul>\n\n\n\n

How to Undervolt<\/strong>\u00a0<\/h3>\n\n\n\nYou\u2019ll first need to download all the necessary software. In our example, we\u2019ll be using CPU-Z to benchmark and test our processor, HWMonitor to keep track of temperatures, and Throttlestop to undervolt. <\/p>\n\n\n\n

How to Undervolt a CPU: Step-by-Step<\/strong>\u00a0<\/h2>\n\n\n\nIf you\u2019re looking to undervolt your CPU but don\u2019t know where to start, we\u2019ve broken it down step-by-step below.\u00a0\u00a0<\/p>\n\n\n\n
What You Need<\/strong>\u00a0<\/h3>\n\n\n\nBefore you begin, you\u2019ll first need to ensure you\u2019ve got the right tools. This includes: <\/p>\n\n\n\n
\n- Your PC with a stable internet connection\u00a0<\/li>\n<\/ul>\n\n\n\n
\n- A dedicated undervolting software such as Throttlestop or AMD Ryzen Master\u00a0<\/li>\n<\/ul>\n\n\n\n
\n- Benchmarking software such as CPU-Z, 3DMark, or Cinebench\u00a0<\/li>\n<\/ul>\n\n\n\n
\n- Temperature and voltage monitoring software such as HWMonitor or Open Hardware Monitor\u00a0<\/li>\n<\/ul>\n\n\n\n
How to Undervolt<\/strong>\u00a0<\/h3>\n\n\n\nYou\u2019ll first need to download all the necessary software. In our example, we\u2019ll be using CPU-Z to benchmark and test our processor, HWMonitor to keep track of temperatures, and Throttlestop to undervolt. <\/p>\n\n\n\n
Once all your software is downloaded, open them all up and run the CPU-Z benchmark whilst monitoring performance via HWMonitor. Here, you\u2019ll want to take note of the temperature of your cores and the maximum voltage that they reach during the benchmark. We recommend you make a physical note of these as this will serve as your starting point, so you don\u2019t want to forget them! <\/p>\n\n\n\n
From here, open up Throttlestop*<\/strong>. You may be presented with a warning pop-up about the software making significant changes to your CPU. This is true, so if you are comfortable with this, press OK to proceed. <\/p>\n\n\n\nIn the main Throttlestop window, locate Speed Shift \u2013 EPP<\/strong>. This should be on the left side. Tick this option. This will enable the Speed Shift technology, otherwise known as Hardware Controlled Performance, which is responsible for improving performance and responsiveness by enabling the CPU to automatically switch to the best voltage\/frequency depending on your workload. <\/p>\n\n\n\n<\/figure>\n\n\n\nFrom here, select the setting called FIVR. This will open up a new window and might look rather scary as it\u2019ll be a huge overview of various settings. <\/p>\n\n\n\n
In the FIVR Control<\/strong> column, make sure the following options are ticked; <\/p>\n\n\n\n\n- CPU Core\u00a0<\/li>\n<\/ul>\n\n\n\n
\n- CPU Core Voltage\u00a0<\/li>\n<\/ul>\n\n\n\n
\n- Unlock Adjustable Voltage\u00a0<\/li>\n<\/ul>\n\n\n\n
To undervolt your processor, you\u2019ll need to adjust the Offset Voltage<\/strong>. You should do this in small increments to help you find that sweet spot. The final amount all depends on your processor. Older CPUs can struggle with big undervolts while modern-day processors, such as Alder Lake, can handle this bigger power adjustment. <\/p>\n\n\n\nStart by tweaking the millivolt (mV)<\/strong> value by a larger amount. What you pick depends on your chip, but \u201350mV<\/strong> is a safe starting point. If your PC continues to function correctly, you can go back and lower the voltage a little bit more. <\/p>\n\n\n\n<\/figure>\n\n\n\nOnce you\u2019ve adjusted the Offset Voltage<\/strong>, switch your selection in the FIVR Control <\/strong>column to CPU Cache<\/strong> <\/em><\/strong>and tweak the undervolt to be the same value as the CPU Core. From here, select Intel GPU<\/strong> and undervolt this slightly. This step is entirely optional but anywhere between 25-50m<\/strong>V is safe. It\u2019s fine to skip this step, especially if you experience stability issues later as it\u2019s not essential for tweaking your temperatures and voltages. <\/p>\n\n\n\nIf you\u2019re happy with everything, press Apply<\/strong>. Your PC may immediately crash, but don\u2019t worry! If this happens, you need to go back, adjust your voltage settings, and go a little easier this time. You may also need to select OK<\/strong> > Save Voltage Immediately <\/strong>> Apply<\/strong>. <\/p>\n\n\n\nNow it\u2019s time for you to put your voltages to the test by running the CPU-Z benchmark and monitor the temperatures\/voltages in HWMonitor. Compare the values to the ones achieved before you undervolted. You should hopefully see an improvement. <\/p>\n\n\n\n<\/figure>\n\n\n\nIf your PC doesn\u2019t crash, we recommend you perform a few extra tests just to make sure everything is fine. Ideally, you should really put your PC to the test by running every application that you usually would, any games, Discord, Chrome tabs, etc. The trick here is to really stress your PC to check for any instabilities caused by undervolting. <\/p>\n\n\n\n
If your PC doesn\u2019t crash and you\u2019re happy with the results, you\u2019ve successfully undervolted your CPU! However, if not, you can go back and repeat the steps listed above but start with smaller 5-10mV<\/strong> increments. <\/p>\n\n\n\n*Throttlestop mainly works for Intel CPUs. If you are trying to undervolt an AMD processor and Throttlestop isn\u2019t working, try AMD Ryzen Master.\u00a0<\/strong>\u00a0<\/p>\n\n\n\n
\n\n\n\nHave You Tried Everything?\u00a0<\/strong>\u00a0<\/h2>\n\n\n\nAre you still struggling with excess temperatures and unstable performance even after undervolting your CPU? There are still a few more things you can try before you give up! This includes trying a new CPU cooler or even reapplying your thermal paste.\u00a0Don\u2019t know how to go about applying some new thermal paste? We\u2019ve got a blog post for that.<\/a>\u00a0<\/p>\n\n\n\nIf all else fails, it might simply be time to treat yourself to an upgrade. <\/p>\n\n\n\n
