./intel-phc-undervolt.bash


This script will optimize your voltages at every speed setting 
by systematically lowering them while stressing the CPU.
Each voltage will be turned down until your system crashes, and the final
setting for that voltage will be 4 VIDs above that to "ensure" stability.

WARNING:
This script will crash your system as many times as there are VIDs to tweak.
You might destroy your hardware, break laws and/or die in vain if you continue.

Do you want to continue? [Y/n/?] Yes
>Found 2 CPU cores.
Multiple cores found, the script will use the
same voltages for all cores, this means final
setting will be 4 VIDs above the weakest core.

Install required packages.
Will use burnMMX (part of cpuburn package) to stress CPU.
Install: cpuburn
> SKIPPED: Already installed

Load VIDs from 'phc_tweaked_vids' file
> Success!
Load position from 'phc_cur_pos'
> Success!
Read available frequencies.
> Success!

Last VID: 23
Replace with VID from previous position.

Default VIDs: 41 34 30 27 23 17 
Current VIDs: 25 25 30 27 23 17

Next VID higher than last - copying.
Switch to 'userspace' scaling governor.
