how to set voltageshift? #13

Closed irfanhutomo2 closed 2 years ago

irfanhutomo2 commented 2 years ago

i see voltageshift.kext in EFI/OC/Kext, but how i follow your sugesstion to set voltageshift? like voltageshift powerlimit 10 10 and voltageshift offset -100 -100 -100 -100 -100 -100 -100 how i set that value

sambow23 commented 2 years ago

If not already, download VoltageShift and move the voltageshift binary to /usr/local/bin via the terminal: sudo cp /path/to/voltageshift /usr/local/bin

then restart the terminal and run the commands

thanks i already set the first value , but second value voltageshift offset -100 -100 -100 -100 -100 -100 -100 make my laptop glitch and then restart, any idea whats happen?

my xps using i5-10210U

irfanhutomo2 commented 2 years ago

i try only voltageshift offset -100 -100 and it's work, but are only set like that help my battery life?

that means your chip cant undervolt that far, its a silicon lottery after all, not every person will be able to go that high. just go in -5mv increments until you hit something stable

Shaquille0atmeal commented 2 years ago

I would recommend starting at -75mV and if that is unstable decrease by -5mV like what was said in the previous comment.

irfanhutomo2 commented 2 years ago

then i only can set CPU and GPU voltage?

Shaquille0atmeal commented 2 years ago

You can change all the values. That shouldn’t be an issue.

irfanhutomo2 commented 2 years ago

oh i can try like this? voltageshift offset -75 -75 -75 -75 -75 -75 -75 ? and if this not work i up the value to voltageshift offset -80 -80 -80 -80 -80 -80 -80?

am i right?

Shaquille0atmeal commented 2 years ago

What you would do if -75mV were to fail would be do DECREASE instead of INCREASE, so you would do -70mV if -75mV crashes the system. But If -75mV IS STABLE, you can try bumping it up to -80mV and see if it is stable then.

thankss for your guiding i try -80mV and stable i think for a minutes , the i can increase to -85mV right?

Shaquille0atmeal commented 2 years ago

I would recommend doing a few things on the machine first, test it for 15 or so minutes, and if it's stable then, continue to increase until you see instabilities.

can i do like this? voltageshift offset -100 -100 -85 -85 -85 -85 -85

Shaquille0atmeal commented 2 years ago

If it is stable, yes.

irfanhutomo2 commented 2 years ago

i dont know why, when i set like that i cannot restart,

i think my stable state is voltageshift offset -70 -70 -70 -70 -70 -70 -70

irfanhutomo2 commented 2 years ago

any suggestion for free apps that run script automaticly after sleep?

sambow23 commented 2 years ago

I use Power Manager to apply these offsets on boot and wake from sleep (these > offsets may not work for every configuration, take caution and ymmv.)

thanksss
