@JorgeB thank you for the link.
I did a CLEAR CMOS and loaded optimized defaults and went through the BIOS again.
There is no such thing as "Power Supply Idle Control" although I could have sworn that in the past I have seen this setting. Maybe it was removed after a BIOS update.
There are other settings though, ERP Ready, Energy Star Ready, CEC Ready. Tha later two I leave usually disabled. But I enable ERP Ready.
I also disabled now global C-States. Will this mean that my power drop of the server will go up? Will it go up considerably?
Also my ECC RAM is running on 3200 MHz. This is not a D.O.C.P Profile, in fact, there is no profile stored on the RAM. Can I just lower the frequency in the BIOS for the RAM an expect no problem? As far as I know the highest supported speed is 3200 MHz. Not sure if lowering it would give me any benefit.
