I'm running Xeon E5-V4 processors on a few Asus X99 WS and X99E WS motherboards. There are lots and lots of options in the bios for various link and other power management features which are disabled by default. I do see that many of these are enabled on brand-name pre-built workstations and servers as default settings.
SATA ALPM - any reason not to enable aggressive link power management?
SA SMI ASPM?
PEG ASPM?
PCH DMI ASPM?
ASPM support? (various on board devices)
Asus branded "EPU" powersavings?
I know it doesn't save the whales or anything, but no point in burning power on a machine that has a fair amount of idle time doing not a lot in the home lab.
