This changes EVERYTHING! OCCT v13 will be released for Linux also. If this is true, it will be the first time in the history of Linux that we will have access to hardware info and stress tests, all in one app!
for Ryzen cpus there's ryzen_smu which appears to be able to do this. not sure about Intel.

Can all Zen 3 APUs run 4x 16GB 3200MT CL16 stable? (just XMP)
For sensor and whatnot, check out corefreq and ryzen_smu.

Can someone please tell me what is wrong here when installing 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.

Boot failure on kernel 6.2
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.

Core-to-core latencies of the AMD EPYC Milan, 3rd gen
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.)

RAM won't run at XMP speeds
Check out corefreq and ryzen_smu; they're for sensor readouts, and they do slightly different things.

Tri-rank 3801MT/s 1T-off: how to summon Baphomet with the CAD bus
That said, the ryzen_smu tool for linux exposes "CLDO_VDDM", which reads out to 0.9504 volts, regardless of load.

B die, Ryzen 5700 help with starting.
Check out this guide. Also check out Ryzen SMU for better sensor readings on linux.

3900x L3 Cache errors
I forgot to mention, Ryzen SMU can be used to for sensor reading.

is there any overcocking tools for linux?
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.

C-States Ryzen 9 5900x
That being said, you can likely find more detailed monitoring info using this tool instead since it shows power, voltage, frequency and C-State residency all in one app.

12700K vs R7 5800X in CPU-Z Stress Test (25mins) using Noctua NH-C14S in 21°C Ambient
You can read through that blog post if you're curious (there's part 2 dedicated to the software measurements). There is no official software that reports that, but you can use the reverse-engineered tool (it's for Linux though).

Which is the correct CPU temperature? - Ryzen.
How can I state all this confidently? Because I've reverse-engineered Ryzen Master myself and even wrote a Linux driver to show you exactly what Ryzen Master shows. In fact there's a lot of information it leaves out as well. I haven't ported it to other processors aside from my own 3700X but this spinoff project does add support for the 5000 series and quite a few other 3000 series processors. If you're looking for a "Ryzen Master" like monitoring tool, that will almost certainly work.

4 core 5 GHz, Is it possible to keep the boost clock as a normal clock if thermal and power are enough like Intel? what is preventing the clock to keep standing? I turned off one CCD on my 5950x and the maximum power consumption is 117w for the 8 cores and thermal is acceptable 73c which is fine.
Windows tools don’t show that FIT limit but you can view them on Linux. Use that tool and experiment, I’m gonna bet that you’re hitting FIT limits preventing it from boosting higher and consuming more power.

Ryzen 5600X High PPT draw when idle
In fact, HWiNFO64 and Ryzen Master both pull their information from a sub processor called the SMU. You’ll see this if you open HWiNFO64 and look at sensors. Some will have an ‘(SMU)’ prefix, indicating the information source is the same. This project essentially does the same thing but provides even more detailed info into power consumption as it shows other RoC rails in detail.

[Phoronix] AMD Is Hiring More Linux Engineers For The Scheduler, Memory Management, Net I/O
Try this. Should give you even more information than RAPL or the amd_energy driver.

[General Question] I've seen mixed answers regarding 5600x voltages. As a new 5600x owner, what do I trust?
For the 5000 series (since although I have reverse engineered the basics for them, I didn’t invest time to port my monitoring tool for those), you can use a derived project from mine called Ryzen monitor that would also show you this.

5950x Linux lmsensor output
If you'd like more in-depth monitoring, you can use this which would give you results like this.

How to monitor per Core Temp on 5800x?
If you’re using Linux, you can view them. Needless to say you can’t do this on Windows unless you port that functionality to it, otherwise you’d need to stick to the regular Tctl/Tdie/Tccd temperatures.
What are some alternatives?
