What is GPU Undervolting?
GPU Undervolting is changing the operating voltage of the graphics card or video card while retaining its core clock speed. GPUs can be lowered to a safe working voltage with optimal minimum voltage for the same GPU frequency by lowering their maximum operating voltage out of the box or with factory settings.
As an example, let’s say the default setting of a GPU is 1850MHz and 1000mV voltage. To keep the 1850MHz frequency, you can reduce the voltage to 975mV or 950mV if you don’t encounter any problems. This is known as GPU Undervolting.
By doing so, it will produce a cooler temperature result (when compared to the default settings) as well as reduce power consumption, resulting in quieter operation and longer lifespans. If the frequency and voltage of your graphics card are highly volatile when it is set to factory settings, then undervolting your graphics card might be another good idea. Let’s now look at how to undervolt your graphics card.
Is Undervolting a GPU Safe?
Undervolting a GPU can be safe if done properly. A GPU can run more efficiently and potentially improve its performance by undervolting the GPU, which involves reducing the amount of voltage sent to it, which can help to lower its power consumption and temperature. This can be achieved by lowering the voltage sent to the GPU.
The GPU can become unstable or even damaged if the voltage is set too low, so it is important to carefully follow the instructions for Undervolting. Monitoring the GPU’s temperature is also important to make sure it doesn’t overheat. Undervolting is generally safe and effective if done correctly.
Prerequisites (Requirements)
To undervolt a GPU, NVIDIA 10 series or higher GPUs, or AMD GPUs, must be used as prerequisites. The lower series GPUs have been reported not to work well with undervolting, but it is possible that higher series GPUs will work just fine. AMD GPUs are generally easier to undervolt, but it is still important to do research and understand that different GPUs can produce different results.
In addition to the type of GPU, Undervolting requires several tools and information as well. You will need a program such as MSI Afterburner or EVGA Precision X that can adjust the GPU’s voltage. Additionally, you will need to know the default voltage and clock speed settings for your particular GPU, as well as the safe operating temperature range. During the undervolting process, a temperature monitoring program is also recommended to track the GPU’s temperature.
The process of undervolting a GPU requires careful consideration of the prerequisites and ensuring that you have the necessary tools and information.
