How to Disable CPU Boost on ASUS Zephyrus G14?

Question

I recently purchased an ASUS Zephyrus G14 laptop and noticed that the CPU temperatures are quite high during heavy workloads, even when the performance doesn't seem to require it. I've heard that disabling the CPU boost feature can help with temperature management without significantly impacting performance.

Could someone please guide me on how to safely disable CPU boost on the Zephyrus G14? I'm not very familiar with the process and want to ensure I'm doing it correctly.

Also, I'd be interested to know if anyone has experienced any drawbacks or issues after disabling CPU boost on this particular model.

Any help or advice would be greatly appreciated! Thanks in advance.

I can understand your concern about high CPU temperatures on your ASUS Zephyrus G14. Disabling the CPU boost feature can indeed help manage temperatures without a significant performance impact for most tasks. Here's a step-by-step guide on how to safely disable CPU boost:

Open the Windows Start menu and search for "Edit Power Plan." Click on the result to open the Power Options window.
Click on "Change advanced power settings."
In the Advanced settings window, scroll down and expand the "Processor power management" section.
Expand the "Maximum processor state" option.
Change the value for "On battery" and "Plugged in" to 99% (or a lower value if you prefer).
Click "Apply" and then "OK" to save the changes.

By setting the maximum processor state to 99% or lower, you effectively disable the CPU boost feature, as the processor will no longer be allowed to reach its maximum frequency.

I have personally disabled CPU boost on my Zephyrus G14 and have not experienced any noticeable drawbacks or issues. The laptop still performs very well for my needs, including programming, video editing, and light gaming. The temperatures are more manageable, and the fans are less audible under load.

However, it's worth noting that if you frequently engage in tasks that heavily rely on CPU performance, such as rendering or intense gaming, you might notice a slight decrease in performance. In such cases, you can always re-enable CPU boost by setting the maximum processor state back to 100%.

I hope this helps! Let me know if you have any further questions.

Another way to disable CPU boost is through the BIOS settings:

Restart your laptop and press F2 to enter the BIOS
Go to the "Advanced" tab and select "AMD CBS"
Choose "NBIO Common Options" and then "Precision Boost Overdrive"
Set "Precision Boost Overdrive" to "Disabled"
Save the changes and exit the BIOS

This method is a bit more involved but can be a more permanent solution. I've found that it provides a good balance between temperature control and performance on my Zephyrus G14.
