ryzen_smu VS RyzenAdj

for Ryzen cpus there's ryzen_smu which appears to be able to do this. not sure about Intel.

For sensor and whatnot, check out corefreq and ryzen_smu.

Attempting to install Ryzen smu on fedora and I am using the "Stand-alone" installation as I understand that fedora/debian/arch are different.

Only out-of-tree modules being run are drivers for rtw8852be wireless card and ryzen_smu. The retbleed flag is not set and I'm running ext4, not f2fs.

For AMD, if you have query access to the SMU coprocessor, you could use corefreq and ryzen_smu; they're for sensor readouts, and they do slightly different things. ​(And Zentimings and HWiNFO for windows.)

Check out corefreq and ryzen_smu; they're for sensor readouts, and they do slightly different things.

That said, the ryzen_smu tool for linux exposes "CLDO_VDDM", which reads out to 0.9504 volts, regardless of load.

Check out this guide. Also check out Ryzen SMU for better sensor readings on linux.

I forgot to mention, Ryzen SMU can be used to for sensor reading.

CPU/RAM overclocking is best done via the firmware, so at worst you're missing out on sensors and other readouts. That said, if you have a ryzen, there are a number of tools available.

Out of curiousity how the 7840HS performs at different TDP, I did some benchmarks using Geekbench 6.2.0. To change the TDP, I've used the software RyzenAdj like so:

TLDR: Ryzen Adj.

A few years ago I did a bunch of poking w/ a 4800H, you can see the actual mechanics of using RyzenAdj. There are also Geekbench 5 benchmarks linked from the doc at different power limits which you can compare to 4800U devices on Geekbench's site: https://github.com/lhl/linuxlaptops/wiki/2020-MECHREVO-Code-...

Note, each laptop manufacturer may choose their different power limits (and like Intel, AMD's curves are largely driven by temperature, so dependent on cooling solution and other settings).

This is a good summary of some of how Ryzen Mobile's power limiting works (actually, read that whole wiki if you're interested in the topic): https://github.com/FlyGoat/RyzenAdj/wiki/Renoir-Tuning-Guide

I'd also look up "AMD PMF" (their equivalent of DPTF) which only recently made it's way to the Linux kernel (but of course, that will include loads of details anyone can look through): https://www.phoronix.com/news/AMD-PMF-CnQF-Linux-6.1
