Yap, that method of measuring is better. I think I need such device too.I was speaking about total system power consumption (measured with watt-o-meter in power socket). In HWInfo all the time it shows me (in idle) CPU around 6-8W, DRAM around 2W. But the funny thing is it was showing similar values when I had ~56W consumption from the 'wall' and ~36W ... so I do not trust it so much
Anyway I just checked C3/C6.
C3 can be enabled now and C6 can be partial enabled (I've 2x option C6 in BIOS setup, second one for memory/PCI-e etc. still doesn't work).
Windows didn't freeze at loading - good sign. I'm going to check stability of system.
Values in HWInfo64 become little less, not as good as yours (6-8 and 2W wow!!!) but better than before:
