CPU(OS) is just what the OS is requesting, that doesn't mean the CPU is actually reaching that state. You need a PowerTOP version that has Pkg(HW) indicator. For example in this case, you can see the OS is requesting C10 61% of the time, but the CPU is actually only reaching C2: If you must...

Just to make sure, are you sure the CPU package is reaching C10? This is a PSA for everyone but CPU(OS) is NOT useful. That's only what the OS is requesting. You have to look at Pkg(HW), that's what the CPU is reporting, and Debian 12 comes with a Powertop version that doesn't have Pkg(HW)...

That's even worse than the BKHD... :( I saw someone on Reddit say he'd hit 6W with that board but I've not no idea how he did it. So it comes with C states disabled altogether?

Any news on power consumption on newer CWWK/BKHD/other motherboards? It seems the white board doesn't support ASPM due to 10G chipset. What's the motheboard with better power consumption so far? I got myself an ASUS Prime N100I D4 board and while it does get to C10 and uses 6W, the CPU for...

Do we have the same board? I have the BKHD-1264NAS and it has 2 fans, a CPU_FAN and SYS_FAN. In my case the CPU_FAN is bios controlled and the SYS_FAN can be software controlled on Windows, but not on Linux.

I have the BKHD-1264-NAS, not sure if the BIOS is different but on mine I can enable this option to unlock the BIOS hidden settings, no mod needed: Chipset -> System Agent (SA) Configuration -> Graphic Configuration -> Yellow Screen Workaround: ENABLED It might work for you.

I noticed the system fan thing as well. But I noticed that on Windows I could control it using the LibreHardwareMonitor software, so there must be a software way to do it on Linux. I couldn't find it exposed in the /sys filesystem but there might be a module that has to be loaded first to...

Just another update: I tried the BKHD router and with ASPM enabled at idle it uses 6W (!). It doesn't have SATA ports so it doesn't have a JMB585 on board. Pretty impressive, sadly I need SFP and adding the SFP card (X520) it jumps up to 11W. This makes me think that the NAS BKHD motherboard...

Thanks. Do you have states for the Package C-State? It does seem that Cores have no issue entering C-states but it's the package that doesn't. Also do you have a power meter that would let you measure from the wall?

I feel like the CPU could be entering the C-states just fine as there's a service I use for streaming (MediaMTX) that starts dropping UDP packets when the CPU enters C8. This happens on the ODROID H4, and also in the BKHD board, which makes me think the CPU is indeed entering the states. Why it...

Is CWWK better in this regard or do they have the same issues regarding power usage as BKHD?

Okay I was able to replicate it. I can hit C8, but with my power meter I could see a reduction from 16W to 12W. Not sure if it's worth it but here you go if you want to experiment. I'd love to hear if you can get it lower. Maybe part of it is my PSU, I don't know. 1st Step: This motherboard...

Definitely, my BKHD network appliance doesn't go below 15W and hovers around 18W, looking online it seems my mistake was to order it with SFP+ ports, and it uses an Intel X520 which doesn't support ASPM (there seems to be a way to enable it though but it's apparently buggy). The X710 supports...

Hi again, I tried powering the motherboard up (after 2 days of it being dead) and it worked again. I don't know what happened. The CMOS was cleared though as I had removed the battery. At this point I'm not comfortable using it for any critical services, but I'll try to replicate the steps to...

Hi, I was trying to replicate the steps as I was curious myself, but I wasn't able to, and when I enabled a setting related to memory the motheboard died. It doesn't POST and gives no image. I tried to CMOS clear or remove the battery to no avail. I'm honestly tired of it and I replaced my NAS...

Friend thank you so much! You are right, the real way to disable the JMB585 is to fully turn off the PCIe root port, because the "Disable SATA controller" option in the BIOS does nothing. I did and it's now hitting C8: Really thank you so much, I struggled with this for months. `lspci` helped...

I have the BKHD-1264-NAS board and the CPU will stay at C3 max. I don't use SATA devices so I disabled the SATA controller in BIOS (it has the JMB585) but it still won't go below C3. Is there no way to fully disable the controller and get lower? I read the topic and I saw other people asking...

It says it uses the ASM1164 for SATA so maybe. I'm scared of wasting more money though, I got burned out trying to get my N100 board lower than C3 (to no avail).

Hi, I come asking for help regarding power consumption. I have these boards: 2 x BKHD N100 1264N4L-NAS sold by Topton: https://www.aliexpress.com/item/1005007418165362.html 1 x BKHD N100 1264N4L-PCIE (router) sold by Topton: https://www.aliexpress.com/item/1005008571225409.html I can guess...

Thank you for the great information. I see you have very good power usage but it's a CWWK board; maybe it's the BKHD boards in particular with the problem? I remember a similar Beelink EQ12 (N100) used less on default, like 7-8W. But I just can't get my BKHD/Topton board below 14W on Proxmox...
