Maximus VI Power Saving & Power Tuning Guide - Republic of Gamers | ROG - Republic of Gamers GlobalCPU Power Management Configuration
Set CPU C state to Enabled.
Set Enhance C1 State (previously known as C1E) to Enabled.
Set CPU C3 Report to Enabled to allow the CPU to enter C-State C3 State when the CPU idles down.
Set CPU C6 Report to Enabled to allow the CPU to enter C-State C6 State when the CPU idles down.
Set C6 Latency to Short to allow the CPU to respond to C-State C6 entrance request with a relatively shorter delay.
Set CPU C7 Report to Enabled to allow the CPU to enter C-State C7 State when the CPU idles down.
Set C7 Latency to Short to allow the CPU to respond to C-State C7 entrance request with a relatively shorter delay.
Set Package C-State Support to C7s to allow the system to send I/O devices to low power mode to reduce unnecessary power consumption when the system idles down.
Note that the CPU still enters the later C-States even if the earlier C-States are disabled. However the Package C State Support won’t function unless at least one of the CPU C-States has been enabled.
Doing some research on some of ROGs UEFI settings, I came across the bit above.
It looks as if I need to turn switch the one I highlighted(bold) from C7s to C7, as I turn of all Active State Power Management(ASPM) stuff and everything else the turns peripherals off, like USB, and disks.
There is nothing worst then something turning off or going to sleep when you need it.
But as I have PCIe ASPM off, I might as well change C7s to C7.
@Cliff I've played around with C-States quite a bit and this is how my C-States are setup:
Intel(R) SpeedStep(tm) [Enabled]Turbo Mode [Enabled]CPU C-states [Enabled]Enhanced C-states [Enabled]CPU C3 Report [Enabled]CPU C6 Report [Enabled]CPU C7 Report [CPU C7s]CPU C8 Report [Enabled]CPU C9 Report [Enabled]CPU C10 Report [Enabled]Package C State Limit [Auto]CFG Lock [Disabled]Intel(R) Speed Shift Technology [Enabled]
What I discovered is that enabling the C3 State and downwards does not allow the CPU core frequencies to relax and actually results in more power consumption. This is the trade off for the new Speed Shift which keeps the core frequencies higher for quicker boost clock response. What do your core frequencies idle at with your current C-State config? My setup will let the cores relax to 1200-1500 MHz on average.

Have you tried the XOC bios? I think there are few over on OCN running it with some decent results.
