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.
turn it off 😔
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
I have a server with a Ryzen 3 3200G with a B450 mainboard. The system has 16GB RAM, a boot SSD and a 16TB HDD. With proxmox and a few VM’s installed with low CPU usage I’ve read 25-30W from a power meter.
Keep in mind that the system relies on the integrated GPU. If it had an dedicated GPU the power consumption would probably increase around 10-30W.
I run a 1600X as a Proxmox host, I have used TLP to set all of the configurable that are exposed, and it idles at 70W. There are a few other things consuming power though - a spinning HDD, a discrete GPU (quadro K2200) doing zero work, and four DIMMs.
This is helpful to heat my apartment in the winter, but regrettable overall.
I tried proxmox with a Ryzen 1400, a GTX1060 Ti, 3 HDD, 1 NVMe. On proxmox I had a couple of VM and 1 CT. I had 70W on idle which is too much for me :)
ok that is wild! thanks!
Hmm the prices on eBay really don’t seem that good to me in comparison to newer generations. I guess the power consumption will eat up any savings pretty quickly. Though this might differ for whole sets.
