Calling for some help. I've setup and old chassis to be an ESXi5.5 box for some misc home needs. At the moment 2VM's are running - a pfsense gateway and a Linux NVR for my security Cameras. At present the system is running with a load around 0.1. I'm trying to maximize my power savings but can't seem to figure out why I'm not getting the option of the C1,2,3,4 processor power states, and why its its spending most its time in P0 even with no VM's running. System specific details and run stats are below. Any thoughts are appreciated.

(this is only a snap in time but in practice all 4 cores spend 75%+ time in P0)
