I've been getting coil whine since switching to a new PSU, and I'm worried about power stepping affecting my SSD RAID0 performance, so I did some reading and decided I needed to disable some C-States.

I've been pouring over my motherboard's manual and online literature, and I cannot figure out what I need to change or where it is.

The CPU configuration panel in the advanced settings just has three options, and the only one that seems relevant is Cool'n'Quiet.

Is there anywhere I can change C-States in this BIOS, or am I limited to disabling Cool'n'Quiet?
