Hi,

I have a Dell XPS 13 9350 (i5 6200u and HD 520). I am trying to undervolt my cpu and igpu to reduce heat and fan noise, and potentially improve battery life. I am using Intel's Extreme tuning utility (XTU) to do this on windows. However, I am dual booting with Arch Linux and am not able to find any equivalent tool for linux. I wonder if the settings stay persistent across multiple OSs, so that I can adjust the settings in windows and benefit in linux as well, or if it is just a software mod that is exclusive to windows. If so, do you know of any tool that does this for skylake chips on linux, as I can't seem to find one.

Thanks!

XTU is a software solution, so if the software isn't running settings will be on the default.....

Hmm, so it won't help me much if it isn't running in the background. Is there a way I can save the settings in the bios or something?

It depends if the BIOS has voltage settings or not. Most desktop motherboards offer voltage control settings, but for laptops it's a case-by-case thing.

Dunno man, I don't have an XPS laptop. :D If you fiddle around in the BIOS you may find this settings...
