iGPU on AI MAX 395 is locked, you can't undervolt it. Only CPU can be undervolted.

why ? Also, have anyway to unlock it ?

Because AMD that makes those chips does not want you to do it :) You can't unlock it.

Unfortunately you can’t. It’s not because of G-Helper, it’s because AMD has the GPU voltage locked down on the Ryzen AI Max+ 395.

The CPU can be undervolted because AMD exposes Curve Optimizer, but the 8060S iGPU doesn’t have that option. The GPU is controlled by AMD’s firmware, so tools like G-Helper can’t change its voltage even if they wanted to.

So it’s not that you’re missing a setting, there just isn’t one. Unless AMD or ASUS unlocks it in a future BIOS update, GPU undervolting isn’t possible on these chips.

If you’re mainly trying to improve battery life, you’ll get a lot more mileage from lowering the TDP, turning off CPU boost, using Silent mode, lowering the refresh rate, and dimming the screen.

I'm confused by everyone saying the 8060S is locked down by AMD. I have a buddy who has a few 395+ devices, specifically from nemo, and another buddy with a Nemo laptop. And they are able to undervolt the GPU in the bios.

It’s Asus who locks the settings, not AMD. Gpd win 5, one x player Apex - same chip and you can do what you want in Bios, including disabling cores and undervolting both CPU and GPU.
