Inxi not showing the correct info about clock frequency of the CPU

General system Newbie

Hi,

I have installed EOS-Cinnamon on a new machine

Need your advice regarding this machine for possible purchase

This is what inxi says:

inxi -C

CPU:       Info: 8-Core model: AMD Ryzen 7 4800U with Radeon Graphics bits: 64 type: MT MCP L2 cache: 4096 KiB 
           Speed: 1397 MHz min/max: 1400/1800 MHz Core speeds (MHz): 1: 1390 2: 1398 3: 1397 4: 1397 5: 1397 6: 1396 7: 1397 
           8: 1397 9: 1397 10: 1397 11: 1397 12: 1397 13: 1555 14: 1397 15: 1397 16: 1397

Both min and max frequency are wrong for this CPU.

Is there any explanation for that?

Bug in inxi command if you are right.

Base Clock 1.8GHz = normal max
Boost 4.2GHz = boost only

So it’s fine i think

If i get it correctly, not sure about min though.

inxi doesn’t show boost

4

Don’t know. Might be.

5

Yeah, that is totally out of the blue.

I think I do get the max (=boost frequency (?) ) for my Intel CPU’s.

6

Double check, i don’t for my i9, it’s only usual max working GHz for me

Alright, I will in a bit.

I have the Ryzen 7 3800x and it reports this so i think your fine. My base clock is 3.9 and boost 4.5

Thanks! It’s alright then. I started worrying a bit that something might be off with the CPU.

I’m facing some more issues initially, like suspension among other things, that I am trying to work out. I will post in another thread if I can’t make it work.

can you return

What else do you need installed to run this besides cpupower?

If you mean cpupower frequency-info then only cpupower from repo.

15

Not sure what this means. Boost is supported but not active?

16

Meaning currently (or if you on battery TLP usually turn it off so you can configure it to turn on there)
Try to stress it and it will be active

17

I am on AC at the moment. I can use s-tui to stress it and see what happens.

18

Or just play 8k video on youtube :laughing:

I’m on a desktop. My boost is game boost setting in UEFI. That’s all i know and it will crank up all the settings. I’m assuming you have the laptop with 4800U. These processor are meant to conserve power so they run lower wattage. I’m sure you can push them but the extra watts will use up battery power and also it will run significantly hotter even if you are running on AC.

You are right. This a Lenovo Yoga Slim 7 laptop.

Thanks for the explanation! Ryzen CPUs are new to me so I guess I have to read up a bit how this particular model works. I post below some results from stressing it a bit.
