I have a Supermicro A3SPI-8C-LN6PF board which features an embedded Intel Atom C5325 CPU running Proxmox (Debian 11.6, Kernel 6.2.11). dmesg
is reporting intel_pstate: CPU model not supported
and I'm wondering what could be the reason. I also noticed that the CPU package power draw is around ~21W when idling (scaling_governor=ondemand
, all cores at 800 MHz) which seems a bit high? More interestingly the power draw only increase to ~28W when running a synthetic load on all cores @ 2400 MHz.
In the BIOS the following settings are set:
SpeedStep (P-States)
enableEIST PSD Function
:HW_ALL
orSW_ALL
; no difference observable.Turbo Mode
: enableEnable Monitor MWAIT
: enabledCPU C6 Report
: enableEnhanced Halt State (C1E)
: enableSoftware Controlled T-States
: disablePCIe ASPM Support (Global)
: auto
