Hi

I just installed the latest proxmox version in a i9 9900k server,
and i am seeing the cpu is always at 5.0Ghz in all cores.
I dont want the frequency stuck at 5.0Ghz, i want c-states working.
How can i solve this problem?

C-States enabled in bios and no overclock!
(Asus rog strix z390 board)

Thanks for your time..
 
You must install cpufrequtils and set GOVERNOR="powersave"
It's what i have done to limit cpu temp and power

Save it...

Apply the configurations so they start at system boot:
Code:
service sysfsutils start


Hope it helps anybody in the future ;)
