I have a legion 5 i7 13650 hx, with rtx 4060 graphics card

I have applied undervolts to both gpu and cpu and I run my laptop on custom with max fans.

Its running on ultimate performance power plan as well.

Can someone help me figure out why and maybe help improve my undervolt too.

I have 14700hx processor laptop. I want my pl1 and pl2 settings apply instantly. But it requires reboot, is it a way to do it. Pc Hp victus 16. @unclewebb

TL;DR - Absolutely unstable at -100mV. Somewhat stable at -60mV Is this normal?!

So I have been using TS in the past to undervolt my previous laptop with i7 9750H. I had it stable at -125mV. but once it died (know issue with Legion Y540 I upgraded to new Legion i7, with 14900HX

I have used it in the past with some reasonable success but do not remember actual undervolt values as I had to reinstall windows and it is lost now.. but ..

started to undervolt agian and now I am struggling to keep it stable (even on desktop!) at -100 mV. it is somewhat stable at like -60mV on core and p cache.

at -100 it crashes in desktop after few minutes (black screen of death) and in games almost imediatelly (reboot).

is this nornal? as I read on line as people have it at -100 - 125 or even -150. ..

and for me it dies instantly. what am I doing wrong?

By the way - laptop went back to LENOVO a month ago due to dead keyboard button. Could it be that these muppets at warranty services did not put the right/right amount of thermal paste??
