Skyfall

The ASRock board had similar results. Stuck in C2. I'm still not convinced that intel_idle is at fault. As I explained there is no specific code for raptor lake in the kernel driver but raptor lake can still hit C10.

H810 unfortunately has a very low amount of lanes. I did compile powertop from source for the arrow lake support but still only max of C2 was possible. Not sure if the chiplet design really is the issue. I tried a meteor lake NUC some time ago and it could successfully reach C10 with an extremely low idle consumption of 2.4W. It seems that without support in intel_idle the ACPI tables are read from BIOS so maybe ACPI tables are wrong?

I was testing with 6.15.4 so that shouldn't had been the issue. I don't think intel_idle is the problem. Are you sure about the raptor lake fixes? There are no specific mappings for raptor lake (13th&14th) gen and those certainly can go beyond C3. I think there was a proposed kernel patch to reuse the same mappings as alder lake but it's not been merged. I have also noticed the increase in power consumption after updating the BIOS. Edit: The same was also true on Windows. I got another ASRock board incoming on Monday to check if it's an ASUS specific issue.

Has anyone reached more than C2 Pkg on a 15th gen CPU? I have a 265k and tried with the ASUS W880-ACE and the Z890M Prime but I just cannot get past C2. ASPM is enabled on all devices (not via script but natively) but yet still the CPU just cannot get past C2. Inside the Bios in the CPU information section it lists C3 State as not supported but C1, C2, C6, C8 and C10 are supported. I wonder why C3 shows as unsupported as it should be available as per Intel specs. I have tried newest ubuntu with newest kernel 6.15 and also on windows but C2 is just the limit resulting in a power draw with nothing attached and every onboard device disabled of over 20W which is just too much. If anyone could share their results that would be really nice. Note that powertop must be compiled from source because 15th gen is only supported in the newest version.

I run the purple CWWK N100 board and it's amazing. Low power consumption ASPM/C-States are possible and there's plenty of connections for storage. https://cwwk.net/collections/nas/products/cwwk-12th-gen-i3-n305-n100-2-intel-i226-v-2-5g-nas-motherboard-6-sata3-0-6-bay-soft-rout-1-ddr5-4800mhz-firewall-itx-mainboard

Only if the board supports bifurcation on the nvme slot.

Kauf dir einfach die M.2 ASM1166 Variante. Dazu dann einfach noch einen PCIe x4 auf M.2 (kostet nicht mal 1€ auf Aliexpress). Damit kommst du am günstigsten weg

Intel unveiled its new Meteor Lake platform in mid-December. By now, the first devices powered by this hardware have been announced. ASUS is releasing a new NUC 14 in two flavors. The models are pretty much the same, except one is slightly bigger and has a SATA storage option, while the other doesn’t. They both have two NVME slots (both PCIe 4.0 x4), one 2280, one 2242, as well as 1x Intel i226V 2.5GbE Ethernet. A WiFi module is soldered right onto the board. Other than that, they come in the usual NUC form factor and are very energy efficient. https://www.asus.com/displays-desktops/nucs/nuc-mini-pcs/asus-nuc-14-pro/techspec/ Even more interesting, ASRock Industrial is also offering NUCs again, which you can get as just a motherboard. These are similar to the ones from ASUS, but instead of having WiFi soldered on, they have an M.2 E-Key slot that is also PCIe x1 allowing plugging in another expansion card. https://www.asrockind.com/en-gb/NUC-155H Overall, these devices should provide an ideal basis for Unraid, as they will be very energy efficient and still offer good expandability. The ASRock board, for example, would allow 2x NVME SSDs and another ASM1166 SATA controller for a total of 7 SATA slots. Moreover, Meteor Lake finally also enables the encoding of AV1 videos. I am excited for when these devices will hit the market
