Any experience with Zen 1 idle power consumption running Proxmox? (lemmy.world)

Hi, I'm planning an doing an upgrade to my hardware and I'm eying a used Ryzen 1700 or Ryzen 1800 (they are dirt cheap now and have an excellent upgrade path once people sell of their Ryzen 5000 CPUs).

I'm however a bit concerned about the idle power consumption of such a System. My plan in terms of Software is to migrate my existing Proxmox System which is running 4 VMs and 6 LXC containers at the moment. Most of which are at < 3% CPU Ut. 99% of the day. Has anyone got any numbers or rough estimates how big the idle power draw of such a System would be? For a graphics card (just to have some kind of display output) I plan to use a GTX 220.

I can't say anything about Proxmox or any power management tool as a fact, but I can tell you that my 1600X is running hella hot at idle on Linux. I'm dual booting and on Win it's idle at 30° while on Linux 60°. Hope this can give some insight, or if anyone knows how to fix this pls tell

You probably need to enable some power saving features that Windows does by default but Linux may not. Run something like https://wiki.archlinux.org/title/TLP just to see if it helps, and then do some tuning because it might be too aggressive.

Ok thanks, it then seems like some Software thing. Are your clock speeds also higher under linux when idle?

The running frequency seems to be the same on both, around 3.5 GHz on idle (weird I know). I'll do some more testing and come back to you with the results
