I got my hands on a used Dell cloud chassis with 4x nodes with 2xQC Intel Xeon CPUs each and 24G ram on each, for total of 96G.
Initially, when first time booting up it consumed 1050-1200W out of the wall. That's insane!
Fans were screaming like hurricane etc.
After a little bit of fiddling, slotting the nodes out and back in again, it stabilized to 690W under 100% CPU load finally. This is still way too much.
No power saving setting in BIOS seemed to help at all. Linux speedstepping was a bit erratic as well.
Took out the 2nd cpu was in my use those are not needed and slotted out half of the ram as well which was dedicated to the 2nd cpu and finally down to 320W under load, measured from the wall!
Now that is sweet: 320W for 4xXeon servers with 12G ECC Ram on each :)
