I ask because of an issue which I asked about here: CPU suddenly locked at a high voltage - Overclocking - Level1Techs Forums
TLDR: Installed qubes, worked well but suddenly my cpu (3400G) starts idling at 1.36 V and that persists across different operating systems (never had this issue in 4 years of using my PC).
I know qubes disables SMT, so maybe it has the power to do stuff like this as well?
The quote was miss-interpreted.
“… my cpu is running at 1.36 V, the same value is reported in gentoo and windows …”
AMD 5 3400G CPU voltage of 1.35 is normal and consistent across operating systems.
" … I could use gentoo on cpupower’s powersave governor and it would report 0.36 V (so really 0.72 V). . . "
Program(s) can be run to reduce power usage. A Gentoo version is linked below
Never mind guys I managed to fix it, I just loaded the default settings for my UEFI (be sure to still change the necessary options after doing that or you won’t be able to boot your pc, like the primary graphics device, enable IOMMU and virtualization for Qubes etc.)
Thank you I managed to solve the issue. I have a new problem now and this time it’s qubes os specific. On gentoo (or windows) the voltage does hover around a fixed value (~0.7 V) on powersave mode but it seems on Qubes OS the sudo xenpm set-scaling-governor x powersave (x is the id of the respective core) doesn’t seem to have too much of an effect; the temperature and voltage jumps all around the place. Perhaps I’ll make a separate thread about it.
