Does proxmox update the clock frequency displayed to the Intel Turbo Boost frequency instead of the base clock frequency when enabled?

I'm not sure if proxmox is updating the CPU frequency when I have Intel Turbo Boost enabled. I still see the base frequency and not the boosted. I could be missing something maybe, but was curious if anyone else had similar issues or knew what might be happening.

Thank you for your time and help.

In a VM, no. On the host, yes.

In the web interface the CPU is reported/displayed as the base frequency and not Turbo Boost frequency. I can see by running 'lscpu | grep MHz' on the pve node the frequency is reported correctly but on the web interface it shows the base frequency.

It's probably part of the CPU identification and not a actual frequency. Can you show a screenshot, as I don't see it in the web GUI?

Besides anything else, the web interface is updated at a relatively slow rate. If you are expecting some kind of real time response you may need to adjust your expectations.

With turbo it's supposed to be 3.9 GHz

What you are saying doesn't make sense in this context. There isn't a need for real time update to get the frequency setting. The bios sets the turbo setting before proxmox even starts up. I think honestly that proxmox just pulls from only one section of the lscpu read out and doesn't have any switching logic to pull the turbo speed enabled or not to then show or switch the displayed frequency.

So your issue is not the very common one of why the clock speed displayed in a vm does not follow the current host speed. It is more that you think the info on the host is incomplete. Sorry i misunderstood. Have a nice day.

I don't see any clock speed in my Proxmox GUI, but that also has very different colors and symbols.
