Smokeless_UMAF VS intel-undervolt

I was going to try this but just want to be sure: https://github.com/DavidS95/Smokeless_UMAF

Greetings. I have an HP Omen 15 laptop with Ryzen 7 5800H CPU which has Vega 8 iGPU. It has 512MB dedicated VRAM. I understand that it's dynamic and increases itself when needed. But this doesn't work everywhere so I need to be able to set it manually. My BIOS version doesn't have that option. Neither HP nor AMD providing something like this (at least not for my laptop). So I saw this while searching. There are videos on youtube about how it works. I wanted to know:

Even if you cant most amd soc support it even the steamdeck using smokeless https://github.com/DavidS95/Smokeless_UMAF

Yesterday I discovered a BIOS tweaking tool Smokeless UMAF and played around a bit to see what it could achieve. After undervolting Pcore/Ecore/Cache of my 13900HX to -120mV/100mV/100mV I encountered AC/DC Loadline options under Core/IA VR Settings.

You need to download Smokeless UMAF from here and boot from a USB with copied files after disabling SecureBoot.

for some reason smartshift works really well on the g15ae you could try giving amd formbrowser a go https://github.com/DavidS95/Smokeless_UMAF and see if that works it most likely will break most controls on the cpu and gpu youll have from the manufacturer side and youll have to find alternatives to manage it but im just a person providing the information what you do with it is none of my business nor my responsibility

10th gen is locked by "Overclocking lock" And "Cfg lock" in bios, you can disable it thru ifr and use any software to undervolt your cpu (throttlestop on windows, linux has its own software (this, probably)). This is a lot safer than just putting voltages in bios as you can guess.

On Windows machines and laptops with Intel cpus, I almost always use Throttlestop to tweak power consumption and thus temperatures. I'd like to do so on this machine as well. I've found this: https://github.com/kitsunyan/intel-undervolt

intel-undervolt - though I may not be using this optimally. CPU: -75, GPU: -50, CPU-Cache: -75

You can use intel-undervolt to modify the voltage, TDP.

I will try your suggestion about limiting power package. I've been using this 3rd party intel-undervolt software, which I'm not sure if it supports granular changes to wattage, but it seems like there is some energy/performance settings there.

I personally use intel-undervolt and auto-cpufreq.

You can also undervolt though software on Linux based OS's. For intel there's these: https://github.com/georgewhewell/undervolt (this one looks more popular) https://github.com/kitsunyan/intel-undervolt (this is the one I use, no particular reason)

intel-undervolt also works fine for Intel laptops (I've used this successfully with my 11th gen H laptop).
