So by default PS is doing -0.100v undervolt for CPU. Can I set it higher, correct some config file maybe? Using throttle stop I found that -0.145v is stable for me. I don't wanna use any thirdparty utilities to set undervolt since Predator Sense is doing it perfectly, I just wanna it to be more aggressive :)

    Predator Sense is doing the undervolting via an underlying XTU service. I've tried altering the profiles saved in C:\ProgramData\oem\PredatorSense, but they never stick and it just defaults back to the -100mv.  I've never had any issues in other laptops with using Throttlestop, so I've been using that to push my undervolt further, and killed the XTU service from the Services App (so the two aren't potentially fighting for control of the voltage level).  Prevents me from reading the voltage level in the Predator Sense app, but I never bother with that feature anyways.

    It is prohibited in bios to interact the system with xtu

    vorob The only best  way to overwrite the PS values its to use TS instead as it was said above it will default to the same values you cant change the profiles they wont be applied 

    Krandor you dont need to kill the ps xtu service because TS will overwrite it with the cpu values you wish to use also if you kill it the gpu overclock might not work either PS needs the service on to run properly
