Hello everybody,
I have 2 very similar Hp Elitedesk G4 mini, the first one on powertop can go on pkg (HW) up to C9, the second one is stuck at C2 and the power consumption in idle is near 5-6W higher than the first even with 0 vm running
Is there a way to check why the second doesn't get higher C-states?
Here is a short summary of both machine
- BIOS settings and version are the same (I exported the configuration and imported into the second)
- both have nvme crucial p3 1tb (same model and firmware)
- both have the same cpu i5 8500T
- both are in powersafe governor
- both are in all "good" on powertop tunable tab
The only difference is the ram. The fist has kingston ddr4 2666 2x16, and second Crucial ddr4 3200 2x16
powertop of the first
powertop of the second
