  1. Your power top screen looks really good! CPU cores are even reaching C10, which is quite a feat. pc3 = is the package c state includibg all controller. (Memory, SATA, network. Etc..) cc3 = is the core c state of the CPU. The core c state should be more important than the package c state, since the cores can use quite a bit of power. The package power will not fluctuate a lot and is more difficult to get lower, because of all the different controllers involved. Laptop power should be more efficient than a full ATX PSU. I am really interested in the power values you will measure.
  2. Ich habe nun jedes SATA Laufwerk einmal einzeln angesteckt und die C-States beobachtet. Ergebnis: alte HDD SAMSUNG HD501LJ limitiert den package C-State auf PC6 neue SSD Emtec X150 240GB limitiert den package C-State auf PC2 HL-DT-ST DVDRAM GH24NSD5 limitiert den package C-State auf PC2 Der CPU geht trotzdem in C7 oder niedriger. Und der unterschied zwischen PC6 und PC2 beläuft sich bei mir auf ca. 3W. Diese werde ich erstmal in Kauf nehmen, bevor ich neue Hardware kaufe. Mein System hat nun 20W mit Laufwerken im Stillstand und ASM1166, sowie 13W ganz ohne Laufwerke und Controller. Intel i5-11400 (-0.05V) 2x8GB + 1x 16GB 2666 DDR4 Asus PRIME B560M-A ASM1166 PCIE NVME to 6x Sata Adapter 2x SATA SSD + 4x SATA HDD + 1x DVD All C-States enabled + ASPM + ALPM TLP + Powertop Auto tune Ich hatte gehofft noch weiter runter zu kommen wie hier: https://mattgadient.com/7-watts-idle-on-intel-12th-13th-gen-the-foundation-for-building-a-low-power-server-nas/
  3. Solution: In the end I plugged every single device individually into all SATA ports to find the cultprits. My findings are: old HDD SAMSUNG HD501LJ is limiting package C-States to PC6. new SSD Emtec X150 240GB is limiting package C-States to PC2. dvd writer HL-DT-ST DVDRAM GH24NSD5 is limiting package C-States to PC2. I did a comparison with the drives sata cables attached and not attached, while booting from USB. (all power cables still attached) The difference between package C-state PC6 and PC2 seems the be around 2,5-3W. The processor either way seems to be going into C7 or lower. For now I will just accept 3W more instead of buying new drives. My current power consumption with all devices attached but in spindown/sleep is around 20W. I hoped to get lower like here https://mattgadient.com/7-watts-idle-on-intel-12th-13th-gen-the-foundation-for-building-a-low-power-server-nas/ But strangely my PC6 vs. PC2 consumption isnt nearly is dramatic as described there. The lowest I was able to get wihtout any drives and no ASM1166 was 13W. Configurration for reference: Intel i5-11400 (-0.05V) 2x8GB + 1x 16GB 2666 DDR4 Asus PRIME B560M-A ASM1166 PCIE NVME to 6x Sata Adapter 2x SATA SSD + 4x SATA HDD + 1x DVD All C-States enabled + ASPM + ALPM TLP + Powertop Auto tune
  4. Hatte hier schonmal jemand Probleme mit dem Onboard Intel SATA controller? Ich habe ein ASUS Prime B560M-A mit I5-11400 erweitert mit ASM1166 im M2 Slot des Chipsets. (6x Sata B560 + 6x SATA ASM1166) Nun habe ich das Problem, dass die C-States nur bis auf C8 gehen wenn kein SATA Gerät im Onboard B560 Controller angeschlossen ist. Sobald ein Gerät am B560 SATA Controller physikalisch angeschlossen ist, sind die C-States auf C2 begrenzt. (egal welcher Port oder wie viele Geräte). Dabei ist es egal ob das SATA Gerät eine SSD, HDD oder DVD-Laufwerk ist. Getestet habe ich dies mit einem Ubuntu Live Boot USB Stick bin dann jeweils die verschiedene SATA Ports mit den einzelnen Geräten durchgegangen. Man kann sogar während des laufenden Betriebs die SATA Geräte abziehen und dann geht der Rechner plötzlich doch in C6/C8. Alles funktioniert korrekt, wenn ich die SATA-Geräte nur in dem ASM1166 stecke, welcher im M2 Slot (auf PCIE konfiguriert) des gleichen B560 stecke. Was sich bisher geprüft habe: - Überall ASPM L1 aktiviert + native - SATA ALPM Enabled und Hotplug disabled - Alle C-States bis C10 enabled - TLP installiert und powertop --auto-tune - den ASM1166 ausgebaut und nur LAN angeschlossen
  5. Did someone ever had problems with the onboard Intel SATA controller? As soon as it's used it is adding 4-5W for me, since c states are limited to C2. My setup: - i5 11400 - Asus prime b560m-a (latest bios) - 2x 8gb 2666 ddr4 1.2V - bequiet system power 9 400 W - only power and LAN connected When I Connect the same SATA boot SSD to different ports, I get very strange results. 1. To chipset b560 SATA ~16W, C2 max 2. To chipset USB3 via Adapter ~11W C8 max 3. To Pcie Asm1166 in B560 pcie slot ~11W C8 max I also tried different SATA devices while booting from USB. As soon as one is connected to the b560 chipset the max cstate will be C2. I already checked the following: - sata hot plug disabled (/enabled does not matter) - sata alpm enabled (/disabled does not matter) - pcie and dmi ASPM native and L1 - powertop --auto-tune and TLP installed. Does anyone have an idea? I would try bios downgrades next. P.S.: setting the cpu memory controller to Gear 2 instead of Gear 1 also saves 3-4W.
