Hi everyone,
I'm really new to Unraid, linux and home servers as a whole, in fact this is my first home server/nas build.
I've been trying to get this working for past few days and really can't get it to decrease the power usage.
Hardware:
M/B: Fujitsu D3243-S12 updated to the latest BIOS version
CPU: i7-4790T
RAM: single stick 8GB DDR3
USB stick with Unraid (tried in multiple different ports)
All SATA drives disconnected (thus Array stopped ofcourse); no PCIE devices connected,
Power supply: Seasonic M12II-850 Bronze tried in both ways - ATX mode, and 12V only - since the M/B supports this. I know I could save a few watts by upgrading to another power supply (and I intend to).
So, the CPU c-states are working just fine - most of the time being at C7; but the package c-state never reaches even C2.
Have tried on Ubuntu also - the same.
On Windows 10, a tool Throttlestop reports that Package C states are locked to C1.
I've tried changing settings in BIOS through and through, disabling all unused devices as far as disabling all sata etc.
What could be the cause of this? could it be just that BIOS/motherboard does not support it?
Please, if you have any ideas what could cause this, do let me know.
