Linux undervolting GUI

Hi everyone,

I was looking into undervolting in Linux, and could only find command line tools, which can be quite tedious when testing, so I've been making an electron app to handle this for me:




If anyone is interested in this I'm happy to package it up and share it on my github.

Release builds here: https://github.com/lukechadwick/linux-intel-undervolt-gui/releases

TODO:
-- Add benchmark/stress test
-- Add hardware info to read out temps/usage/voltages etc
--Maybe an auto undervolt script to find the lowest stable voltage

 

Can I install it using pip3 because I installed George's python script system-wide.

 

Not currently, that's a great idea though, I will add in a check to see if the script is installed globally.

Update: Okay I uploaded 1.0.1 which should detect that you have it installed.

 

This is amazing! But is it possible... crossing fingers and toes... to add support for AMD Ryzen to the mix?? This would make so many people happy, I can't begin to tell you. There's a Discord server - Ryzen Shine with 150+ members already, desperately looking into this. We have full control of TDP, current and threshold temps, but the one missing aspect is voltage - still holding us back...

 

Not yet sorry, the part that talks to the hardware is written by someone else as a a command line utility, which this sits on top of to provide a GUI. If someone figures it out I'll be happy to add it in.

 

Tested and working fine. Only issue is setting via GUI gives a different offset when undervolt script is read as root.
Working fine if undervolt values are passed via terminal or put to run at startup.

Setting via GUI and reading back set voltages through terminal sometimes gives a different offset at decimal points. Other than that there's no issue. You can use the offset calculation formulae in python script as reference. Good job and your SW is featured at Phoronix!

 

Oh wow phoronix haha, that's cool. I think I know what the problem is with reading the wrong value, easy to fix, cheers!

 

A little UI change will be needed for undervolting tool since I feel root password can be copied to clipboard and abused. Its better to call the GUI with pkexec (debian derivatives) rather than writing root password on GUI and visible to users.

 

@Sphynxinator Scratch my request of removing GUI for root pass in Undervolt GUI since copy and pasting the password doesn't work in terminal. Tried everything and Linux is just too secure....
But a suggestion would be to pad the root password with additional blank dots. I think my password can be judged easily.

 

Update with some Benchmark/CPU info features and bug fixes/polish.

 

Let's stick to manual undervolting and we don't want Linux users to be greeted with black screen since we can't back to AC/Battery profile on TS. With Linux you can undervolt really high unlike Windows. Your C0% usage shows Linux is very optimised.
You hacked my PC!! Just kidding I've same 6700HQ CPU as well.
Tried it on Ivybridge CPU and c0% usage is amazing even with 19 tabs in firefox and thunderbird running in background.

 

windows is bloat

even the LTSC version

 

Yep they are. I have saved package list used by LTSC and I felt Standard cheaper W10 was better than LTSC.
If some users undervolt too high say -200mV or more just because Linux is lighter than Windows and render the PC in non-bootable state. Even AC/Battery profile based switching rarely works. I use Xubuntu since Ubuntu is somewhat bloated too me.

 

Installed it and it works fine, was looking for a way to undervolt in linux!
Thanks!

 

Nice app. I will try it on my laptop with a Haswell blast furnace 4800MQ CPU.

If and when you have time, please make it also support overvolting.

 

You can however use undervolt cmd line version with overvolting... I haven't tested it because I only have locked and crippled BGAs.
