4.4 C-States
C-States is a power-saving technique implemented in modern Intel processors. It
shuts down the clock signals and power for idle logic units inside the CPU to save the
energy consumed. The trade-off, however, is a longer latency for CPU to wake up
and be 100% operational. Depending on your application, you can configure these
options to have higher performance (disable “C-States”) or lower power-consumption
(enable “C-States”).
To set C-States and Enhanced C-States:
1. Press F2 when the system boots up to enter the BIOS setup utility.
2. Go to [Power]

[CPU Configuration]

[CPU Power Management]
3. Enable/disable the [C-States] option according to your application.
4. Once set, press F10 to save setting and exit.
