ASUS Zephyrus G14 is a budget gaming beast with a powerful hardware that can keep up with most of the games in the market. Despite having a good balance between performance, battery life, and portability, some users are still looking for ways to improve the laptop’s performance even further, including undervolting the CPU. Undervolting is a process of reducing the voltage supplied to the CPU, which can lead to a number of benefits, including reduced power consumption and heat output, as well as improved performance.
The process of undervolting the G14 is fairly simple, and it can be done using a variety of software programs. However, it’s important to note that undervolting can potentially damage your CPU if it’s not done correctly. Therefore, it’s important to follow the instructions carefully and to test your system stability after making any changes. Before you start, you’ll need to download and install a software program that allows you to undervolt your CPU. There are a number of different programs available, but we recommend using Throttlestop. Once you’ve installed Throttlestop, open the program and click on the “FIVR” tab. In the FIVR tab, you’ll see a number of different settings that you can adjust. The setting that you’re interested in is the “Core Voltage Offset”.
The Core Voltage Offset setting controls the amount of voltage that is supplied to the CPU. By decreasing the Core Voltage Offset, you can reduce the amount of power that the CPU consumes. However, you need to be careful not to decrease the Core Voltage Offset too much, as this can lead to instability. A good starting point is to decrease the Core Voltage Offset by -50mV. Once you’ve decreased the Core Voltage Offset, click on the “Apply” button and then test your system stability. You can do this by running a stress test program, such as Prime95. If your system is stable, you can continue to decrease the Core Voltage Offset until you reach the desired level of performance and stability.
