Running 7.1.0-beta2 on an i3-14100 on an Asus TUF GAMING Z790-PLUS WIFI (latest bios) and this is my powertop

 

from talking to chatgpt to do some diagnostics, it looks like the kernel doesnt have the intel_idle module to help with this.

...

 

intel_idle is not modular, so it won't work with modprobe. This is mentioned in the documentation (https://docs.kernel.org/admin-guide/pm/intel_idle.html). To check if it's in use, you need to instead do:

cat /sys/devices/system/cpu/cpuidle/current_driver

 

Your terminal output shows the cores idling quite a bit. Was there a particular issue you're trying to solve?

Looks like there is Intel_idle at that location.

 

The cores are idling quite a bit yes, but I feel like the system should be drawing less than 30w with 1x nvme ssd and 3 hdds spundown, evga 80+ gold PSU. 

C states are more tied to how you are using your motherboard etc.

Does it have 2.5g etc? often interrupts etc.

 

Are you using the cpu m.2 ssd slot vs the chipset m.2 slot?

Yes it does have 2.5G, how can I check for interrupts?

 

I believe its in Slot 1 so it would be CPU, would chipset be more power efficient?

Moved the SSD to the 2nd M2 slot and ran powertop --auto-tune and was able to let it idle around 23w all night

Nice!

I have a sas card so until I change that a newer one that supports ASPM low energy. I run solar system & battery so effective runs for free. Have 22x drives and it runs cctv & homeassisnt. Hovers around 80w.
 
Have you got the energy saving scripts saved too so they autorun on boot? Autotune isn't permemenrt I dont think.

usbstick / config / go file

I have this is mine, it might help tweak something else in yours?
I also run the AutoTweak plugin

I sent you a PM because I have a couple questions in regards to bios. Have the same motherboard and some similar parts but only get c3. What microcode are you using? 0x104 or 12c? or something else... I am using a newer bios revision but not sure if that would make a difference or not. bios revisions is here
