If you do not already have PBO2tuner you can choose to install it with the script

Note: the script will search for the pbo2tuner exe on your C drive if you do not choose to install it with the script

The script will get your number of cores and display a text box for each type - then 1-30 or use the common values

Not Recommended you can also apply custom power limits (ppt tdc edc)

Once you apply the script will create a scheduled task to run pbo2tuner at startup with your undervolt settings
