Smokeless_UMAF VS UEFITool

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

UEFIPatch from LongSoft's GitHub A UEFI patchtool built on the older UEFITool engine. UEFITool is not needed for this patch, only the UEFIPatch applcation.

Download UEFITool from https://github.com/LongSoft/UEFITool/releases for example UEFITool_NE_A66_win32.zip is hidden behind the show all assets button

There's a discussion here about this being done successfully on a ThinkPad T460 with a SPI programmer and UEFITool. The same method should apply to the T460p.

If HPET is not an option in firmware, then it is disabled (0x00) and hidden from you. Which in practice is bad. The only option for users in this case is to download your firmware from the vendor, use this tool to locate the register and set the value with this tool to enabled (0x01).
