ryzen_smu VS Vermeer

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.

Check the test here: https://github.com/xxEzri/Vermeer/blob/main/Guide.md It shows 5800x3d vs 5900x - especially ram OC is interesting where 5900x with OC ram comes closer to 5800x3d. WIth 5600x should be similar (yet it's slower CPU of course).

If you're looking for sensitivity, consider the games listed in this benchmark.

Cezanne, for it's smaller caches is more sensitive to RAM OC; and given that Cezanne can stay 1:1:1 when approaching 5000MT/s, it's a very good idea to run dual-rank or even single-rank for the frequency headroom. Consider this, but in the opposite direction.

Found this github article to be relevant. https://github.com/xxEzri/Vermeer/blob/main/Guide.md

Consider this 5900X vs 5800X3D.

For your 5800X vs 8700K scaling, it makes sense; it's essentially the same story of what the 5800X3D did to memory scaling for the 5800X; 8700K has very little L3 compared to 5800X non-3D. CPUs with less cache available to a core will be far more sensitive to memory-array performance.

Also look at this to see the difference between jedec and tuned timings. It's basically impossible to give you a number for what kind of performance increase you should expect in your system but these gains you see just from some timings and single vs dual rank should give you an indicator that coming from 2400 14-16-16 you'll get a very big boost in games and workloads where ram matters
