How to see current CPU / memory frequencies

Hello. I enabled some BIOS settings which are meant to enhance CPU and memory frequencies to improve performance. Other than that I might occasionally overclock some hardware manually. I could really use a way to see the real voltages and frequencies at which the CPU, GPU, RAM, VRAM, etc. are running (NOT the stock ones which are specified in Hardware Info). Fan speeds and temperatures would also be useful to see. In Windows I had CPU-Z, and I’d like a Linux alternative of that. Is there either a program in the openSUSE repos which shows them (preferred), a console command to list them (second preferred), or a text file in which the system outputs them?

Since you use KDE ksysguard could be your choice here for some of the
info you want to see. When I open ksysguard and add a new sheet I can
drag and drop cpu frequency into that to show it graphically. For
voltages and GPU I do not know a tool and for the GPU it might depend on
what you have. For nvidia the command line tool nvidia-smi gives a few
infos.


PC: oS 12.3 x86_64 | i7-2600@3.40GHz | 16GB | KDE 4.10.0 | GTX 650 Ti
ThinkPad E320: oS 12.3 x86_64 | i3@2.30GHz | 8GB | KDE 4.10.0 | HD 3000
HannsBook: oS 12.3 x86_64 | SU4100@1.3GHz | 2GB | KDE 4.10.0 | GMA4500

I use KSysGuard a lot to see top process and CPU / Memory usage. But I never saw any way to list frequencies there. How is it done exactly… I can’t find those sheets.

When I start ksysguard I have a menu on top: file, view, settings, help
Choose
File -> New Tab
(I use it in german so I did not see it is called tab in the english
version) a small dialog opens with number of rows, cols, update interval
when you click ok an empty new sheet is created and on the right side
you have a tree with a lot of sensors, just drag the ones you are
interested in to the place on the sheet where you want them.
The sheets are persistent so you do not need to repeat that the settings
are stored.

Ahhh… had no idea about those custom tabs. Really awesome feature and useful for many things :smiley: I managed to add a CPU clock frequency graph which works as intended (under CPU Load - System - Average Clock Frequency (float) ). How do I do the same for memory however? I don’t see an option for the RAM boards there.

Another option is to use my CFU Utility: https://forums.opensuse.org/blogs/jdmcdaniel3/c-f-u-cpu-frequency-utility-version-1-23-use-cpufrequtils-package-40/

Thank You,
