Not a rant, but was wondering:

If I undervolt Ryzen 5 3600 using Ryzen Master from windows, do I get the changes when I boot into my Linux distro? 🤔

AFAIK, no. Ryzen Master applies its changes on OS boot and those changes are not propagated to BIOS.

The software's documentation and relevant online resources will be a far better place to ask than here, too.

Not sure about Ryzen, but that's how it works on the Intel side. Overclocking settings are reset on cold boot, but survive reboots.

@gronostaj that’s weird af.

@bahua I've checked the official docs. There's no support for linux yet, nor any reply from amd on many of the forum posts.

why won't you just use your mainboard's BIOS settings?

@gronostaj just a small aftermark, they don’t „survive“ reboots, they are saved in a file and applied again after the reboot.

@iiii I AM, using bios to undervolt right now. But not getting the expected thermals. My bios is updated. Everyone in the internet are claiming that there are bugs in the bios for most of the mainboards or isn’t optimized to get the same result as Ryzen Master yet.

@010001111 No, that's not what I meant. If they were saved to a file, they would be applied after a cold boot too, but they wouldn't work when changing OS. It's the opposite. They don't get reset when you reboot, but they do when you power off. If you overclock/underclock on Windows and then reboot to Linux, these changes will still apply. It's a volatile setting that clears when CPU goes off.
