Hi hoping for some pointer please to improve my power efficiency, which is currently sitting at around 38w. With all drives and lan disconnected I can reduce to around 28w, can I do anything to reduce this further ?
I am wondering whether the power supply is old, or whether the Motherboard is a limiting factor?
Running out of ideas...
My set up is
M/B: Gigabyte Technology Co., Ltd. Z590 GAMING X
BIOS: AMI Version F7 Dated 04/14/2022 8ARKL017
CPU: Intel® Core™ i3-10105 CPU @ 3.70GHz
Memory: 16 GiB DDR4
Network: Realtek RTL8125 (rev 5) bond0: fault-tolerance (active-backup), mtu 1500
Sata Controller Intel 43d2
PSU Coolermaster RS-460-PCAP-A3
Boot - USB thumb drive
HDD 2 x WD RED WD40ERFX-68N
I have installed powertop and run autotune, and Tunables are all Good
Under Idle stats Core (HW) are all around 93%
However Pkg(HW) C3 (pc3) is at 80% and nothing at higher states
Also ASPM are all Enabled:-
