Low frequency on the VM's CPU

[COMALXD]

hi everyone,

I installed PROXMOX on an I7 13700k.

But the clock on the Host machine is at 3.4Ghz, and I configured it in the bios to run at 5.3Ghz.

This is making the VMs run at 3.4Ghz and causing me to lose performance.

Any way to resolve this?

I already changed the governor to performance with the command:
"cpupower frequency-set -g performance"


But it was no use.

With "cpupower frequency-info" I can see that it is at 5.3Ghz but this is apparently wrong


Proxmox version is 7.3-6.

Because of virtualization, the VM always see the base frequency even when the CPU is turboing/boosting. Check the Proxmox host for the real CPU frequencies.

ah yes I understand, which command line do I use to show the real CPU clock ?

Try something like cat /sys/devices/system/cpu/cpu*/cpufreq/cpuinfo_cur_freq or cat /sys/devices/system/cpu/cpu*/cpufreq/scaling_cur_freq. The second one works here with my old Intel CPUs and shows the Hz of all cores.

The first one didn't work but the second one returned the Clocks, apparently everything is ok.

I have the same CPU running. I don't have any issues with the Clock. When I run the first command without any process the output is the same of you printed. So I ran a VM and put some video to run in it and I run the same command again. The picture is the second command:
