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!

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.

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.

Mine installed just fine, but this plugin is causing incompatibility issues with intel_gpu_top

Can confirm it worked after uninstalling SRIOV plugin

I had intel_gpu_top running fine for awhile, but I was doing a lot of hardware and software all at once and I'm not sure which one broke it. I did took of the GPU though and intel_gpu_top is still not working. @ich777 may be able to point us to the right direction.

Yeah I am facing this issue as well. HW transcode wasn't working for me because I had my 1050ti on it. I removed it, and now HW transcode works again.. I am on RC5 btw.

reinstalled unRAID or intel_gpu_top?

Thanks for the info!

I was actually going to go Proxmox route before unRAID but I couldn't get the installer working. Mine was just getting stuck at the installer.. Got a guide somewhere? Speaking of unRAID version, what were you using before? My first install with the Asus Prime Z790M-P D4 was RC2. I was able to reach 5sh watts at C10 but it's not constant and was more like 8w on average. Man I wish I got the Intel NIC instead since those 8w with it installed is good! My thought with the CX4 is that it's SFP28 and it's more future proof in the event I upgrade my switch in the future. Also more data points. I decided to try the be quiet! Pure Power M 850W PSU because I'm think of using my unRAID server to host a gaming PC VM. To my surprise, idle power is the same (if not lower since I added an extra fan) as the PICO PSU. Dark Power 13 850W may probably even more efficient but I don't want to spend more $$ lol.

I think only ITX and mATX boards only though. I've tried 3 Z790 mobos, and only the Asus Prime Z790M-P D4 was able to achieve C10. Both my Asrock and Tuf ATX motherboards were only able to achieve C6 max.

I honestly gave up on achieving the deepest C-States.. Even if I get the X710, once I run my Home Assistant and zwavejsui container, C-States immediately drop to C2. I guess the Zooz Zwave dongle probably is the culprit, not necessarily the zwavejsui, but I do use quite a few ZWave devices so I can't just drop ZWave.. Oh well.

Well unfortunately @TheLinuxGuy, I don't have that mobo anymore. I broke it while I was reinstalling my CX4.... LOL. The mobo that I originally got to replace the Asus Prime Z790M-Plus D4, wasn't letting me go into deeper CStates, so I returned that for an Asus Tuf Z790-Plus D4, which also wasn't letting me go into deeper states. So yeah full size ATX mobo's are no go, especially for Z790. Anyways, those seem right.. I have a 13600k so I'm not sure if that's enough variance... What I do remember though is I set Multicore enhancement to disabled, and there was a setting for "Best Case Scenario" (i forget which one it was...). Anything motherboard vendor specific settings was basically turned off, and I used mostly Intel's default settings. I also capped my PL1 to 35W and PL2 at 125W, and unplugged my HDMI cable. Forgot to mention that I was only able to achieve C10 when I let it sit long enough, but in reality, it was mostly at C8, similar to what you have. Oh and for ASPM settings, I used C10 as max, not Auto or CPU Default. More edits: Install corefreq-cli, it should show you frequencies at faster poll rate.

I was having an: unRAID kernel: ACPI BIOS Error (bug): Failure creating named object [\_SB.PC00.PEG1.PEGP._DSM.USRG], AE_ALREADY_EXISTS (20220331/dsfield-184) Removing the GPU Statistics Plugin solved that bug as well.
