I’ve noticed over the years a LOT of Linux users do no have their system sensors / CPUs setup properly. Mostly missing fan information, missing / incorrect sensors and most importantly improper AMD CPU PSTATE and governors. For example, the past few years I’ve had to ensure I had correct kernel drivers and boot kernels parameters for my AMD 5950x to properly use the correct governor and idle at 500mhz and for correct sensor information and control for my viii dark hero MB.
Thanks for this, I was wondering why Linux was using more power (on my UPS) compared to Windows.
I just added
amd_pstate=passive
to grub and it brought it down ~15 watts, there's other options but I believe they require kernel 6.3 or higher. More info here.Also I was using this before but for other people, if your it87 based sensors aren't showing up, frankcrawford maintains an updated it87 module.
With kernel 6.5+, the default is now
amd_pstate=active
for Zen systems.I recommend
amd_pstate=guided
for 6.4+ though as at least on my machine, this seems to yield the best performance/energy trade-off.
