Hi,
Thanks for this topic! I try to reduce the consumption of my setup and have found many answers here.
My server currently idle at 21w (from wall) when HDD off.
Motherboard : asrock z390 phantom gaming-itx/ac
Proc : i7 9700k
Memory : Corsair Vengeance LPX 2x8 16GB Dual Channel DDR4 Kit 3200MHz
HDD1 : WD 8TO
HDD2 : Seagate 3TB
HDD3 : WD 8TO
SSD 1 : Samsung 860EVO 500GB
NVME 1 : Samsung 970 EVO plus 500GB
In Bios
- all C state enabled in Bios
- ASPM LOs&L1 activated
- Desactivated TB, Wifi, unused usb3 ports
I added Powertop autotune plus extra command lines at startup.
In Powertop i can see that
CPU is going up to C10
Core is going up to c7
Package is not going further (or lower) than C3... (sum of percentage doen't sum up to 100% I understand this is because C0/C1 is not displayed)
ASPM is enabled for everything BUT "PCI bridge: Intel Corporation 6th-10th Gen Core Processor PCIe Controller (x16)"
but in the idle stat I can see that this doesn't prevent desactivation of the card, and I don't have anything plug to it (unfortunately I don't see any setup to desactivate this in BIOS)
Why is my setup not going lower than C3?
Is 21w ok for an i7 9700k and a Z390 with nothing else than a 1GB ethernet and 2 USB (unraid usb and a wireless keyboard (currently used for Bios set up)?
Is there anything I miss?
Thank you.
