Reduce power consumption with powertop

[pOpYRaid]

@dopeytree thanks for your answer.

 

Ok so when i got your right, just enable XMP 
Will try it and measure power consumption again.

 

So my current config is:

• BIOS: EIST/C-States enabled, Turbo boost, Speedstep & XMP disabled
• Added /boot/config/go tweaks from OP (to set powersave cpu governor & other small tweaks)
• Idle consumption is ~11,4 Watt (All docker running, HDD's in standby)

So your suggestions are:

• BIOS: EIST/C-States enabled, Turbo boost, Speedstep & XMP enabled
• Remove tweaks from /boot/config/go
• Use AutoTweak plugin to set powersave cpu governor and other tweaks

Right?

I keep the go config tweaks just remove cpu boost if that is where you control boost on / off. (it can be done in software rather than bios).

• BIOS: EIST/C-States enabled, Turbo boost, Speedstep & XMP enabled
• Only Remove turbo tweaks from /boot/config/go (keep all other settings)
• Use AutoTweak plugin to set powersave cpu governor and other tweaks
• reboot

 

Share how you get on, does it help?

thx @dopeytree i will test this and post my measurement results.

One question, i have seen in the AutoTweaks screenshots that you can set ASPM forthe realtek 8125B driver.
I and others (see above) had bad experiences with this chip on current unraid 7 beta 2 build.
System is stuck C3 or C6 and doesnt reach higher C states.
Also when ASPM is shown enabled by linux.

Do you have such an NIC card and does the AutoTweak's plugin fixes this issue?
Just asking because the 8125 cards are cheaper than other intel cards.

thx

@dopeytree tested the settings. The idle is up to ~13 watt and peaking much more (yeah the boost is visible here).
Now gone back to disable all turbo boost settings and XMP.
Thinked about it an all worked well without and for our use case, the performance is enought.

Anayway, thx for your time.

Wonder if its because of the i3-12100T?

In a previous build I had a 11900T and the base clock was 1.1Ghz which is too slow so always boosting.

My current build is a B760M-ATX ERYING with i5-13500H with base @ 2.5 GHz Boost up to 4.7Ghz

Performance-cores - 4

Efficient-cores - 8

Total Threads - 16

 

anyway enjoy 9w - 13w seems very good. How many drives do you have?

I have 2x 16bay chassis but all spin down when not in use.

Use the server with coral card & frigate for CCTV so on 24/7 now avg around 60w from previous 120w.

@dopeytree
Yeah, the base clock of the i3-12100T is 2,2 Ghz @ 4x p-cores & 8x threads, which is enough for us.
I have 1x Samsung 980 nvme & 3x Seagate (2x 20TB & 1x 14 TB) hdd's.

 

I am happy with this build now regarding power consumption.
 

One thing i have to solve is the 2,5 GBE Upgrade.
With the RTL8125B i had a bad experience stuck in C3.

Maybe i'll try the i226-T1.

Do you have 2,5 GBE?
If yes, which adapter?

The Broadcom 9500-16i HBA card supports C7:

@mgutt thx for your info. So when i assume right, that's without the intel i226-T1 card, right?
Would be so nice if you could plug it in and check c states and stability.

 

thx a lot

I will. I'm waiting for a bracket to re-position the power supply. I think I receive it in 2 weeks.
