How to tell if CPU ramps up and down?

Featured Replies

Hi all,

 

Bit of a random question. 

So I have a Xeon Gold 6148 base clock 2.4Ghz with a boost up to 3.7Ghz

 

Thing is in the unRAID dashboard it never changes, it only reports 2.4 which is fine.

But then I created a Windows VM and it too never changes when looking in task manager. 

I just setup the Windows in Docker and same thing, 2.4Ghz and never jumps around like a normal PC.

 

This made me wonder if the CPU is boosting or not? 

I am running 7.0.0RC1 but it was the same on the 6 series too. 

 

Is there a linux command I can run on the unRAID terminal to check if it's boosting or not on the host? 

Or is there some BIOS setting I'm missing thats causing it to just chill at base clocks? 

 

Thanks

This is normal with a VM, see if this shows it boosting:

 

watch -n 1 grep MHz /proc/cpuinfo

Ironically thats even worse :)

Its showing its bouncing between 999 and 1000 and no higher :D

 

Then I remembered I had set the 'Power Mode' to Best power Efficiency

I switched it to Best Performance and its up to 3700!

 

So I'll leave it back on Balanced... Thanks

 

And thank you for the quick reply!
