Clevo P750TM Voltage not applying correctly?

[ClassicGuy]

I decided today to just make an account instead of just browsing topics day after day trying to see if anyone else has my issue, I have been trying to undervolt my Clevo P750TM1-G, well the Sager variant of it. I can set my voltage as low as I want in throttlestop but it will always be about 0.1-0.3v higher, and fluctuates a lot. I really want to find a way to stabilize my voltage so I can undervolt my i7-8086k as much as humanly possible, cause the cooling in the stock configuration isnt great and I dont exactly got the money to just buy upgraded cooling right now. I have even tried setting the voltages in the EFI, which is stock and that didnt fix the voltage issues either. I made a short recording of how much it fluctuates at idle, and it can get even worse sometimes. Are my VRMs screwed up?
