hello folks i bought a 13600 along with an MSI z790p pro series motherboard and i'm a little bit perplexed.. the system idles with an array of 4 HDs and 1 NVME at roughly 90w-110w.. looking through the available C-states it looks like there's only 2 available c-states  which doesn't make any sense since most intel CPUS have C1-C10 available.. atleast for these new raptor lake CPUs... i am running on version 6.12.0-rc5 which does have the new linux kernel that should include optimizations on Raptor lake CPUs.. 

 

I'm using the stock intel_Pstate drive along with the Performance governor.

 

even with the dockers on it doesn't significantly increase idle wattages usage.. with about 25 docker containers on i'm around 153w.. 

 

I've seen some other's with well over 20+ HDs and dockers idling at 110W in recent posts so i'm kind of perplexed..

 

not sure if they are all running at downclocked rates or..? i was on V6.11.5 and i tried using powertop and corefreq to control idle states. Best i ever got was around 60w of idle which is ok but the CPU was hard capped at 800mhz..

 

 

 

 

EDIT: i've made some changes into the bios to force enable C1E state as well as manually selecting the idle state max to C10 in bios..

after that it looks like i get an additional C3_ACPI state

You might need to enable them in the BIOS. High end mobos tend to default to performance settings with little regard to efficiency.

I've enabled intel C-State and set it at C10, I've also enabled C1E support, and enabled Speed Shift.. all those changes enabled the extra C3_ACPI state, but i'm just scratching my head as to there only be only 3 c-states?

From my experience (I tried 3 Z790 mobos now), only the Asus Prime Z790m Plus D4 was able to achieve C10 states. My theory is full size ATX motherboards have a lot more features/circuitry going on compared to mATX and ITX mobos. In the end, it didn't matter and I ended up settling with the Tuf Z790 Plus Wifi D4 because zwave-js-ui was preventing deeper C States. I'm also thinking of putting a dedicated GPU.

how is your experience on that TUF series board? i managed to get power usage down to about 72 watts when full idle with 20 dockers alive and 4 HDs connected 1 spun down. had to update to the new 6.12 RCs to see if the new kernel would make a difference on the C state but so far nothing..

As a motherboard it's fine. I may use it for my gaming PC instead, but I do think if you want max power savings, I would not recommend it or any other ATX motherboards.

iono i feel like every manufacturer will have something... in the end its not THAT bad.. i'm on a fully stock 13600k with 5.2ghz boost running anywhere between 60-80 watts of power with like 25+ docker containers.. (one is a project zomboid container that runs constantly..) and 4 drives(1 drive is spun down most of the time) + 1 NVME so i'm not too concerned.. Even with like 6-10 plex streams it'll peak at like 110 for a second as it loads then drop back down to 60/70watts. I guess i can't complain haha

thanks for the help though!

Yeah every manufacturer will have it's quirks. The other ATX mobo I tried was an AsRock. Their power saving features in the BIOS isn's as robust compared to ASUS IMO. But for power saving, it's not manufacturer dependent but more like the board size/feature set. My theory is that ATX just have so many wiring and intricacies compared to ITX and mATX. I haven't tried an ATX H series mobo though so who knows, but yes I agree, it's not THAT bad hence why I haven't bought another mATX mobo lol. Besides like I mentioned, Z-Wave is somehow limiting my CStates.

 

And np!
