Intel® C-STATE Architecture
C-State, a processor power management architecture developed by Intel, can
further reduce power consumption from the basic C1 (Halt State) state, which
blocks clock cycles to the CPU. C-State is an idle state, and instructions are not
processed by the CPU. A brief explanation of all the C-States are as follows:
C0 - Active. The CPU is processing instructions.
C1 - Auto Halt. The core clock (CPU) is off. This is the most basic idle state.
Some CPUs support C1E (C1 Enhanced) for lower power consumption.
C2 - Stop Clock. Both the core clock (CPU) and bus clocks (I/O) are off.
C3 - Deep Sleep. The clock generator is off.
C4 - Deeper Deep Sleep. Reduced VCC (Voltage supply).
C6 - Cache Power Off. Power is turned off to all caches.
C7 - Processor Specifi c. Leaves the initialized application processor in a
processor-specifi c low C-State. For Intel Core i7 processors, this is the lowest
C-State supported.
C1E Support
Select Enabled to use the "Enhanced Halt State" feature. C1E signifi cantly reduces
the CPU's power consumption by reducing the CPU's clock cycle and voltage during
a "Halt State." The options are Disabled and Enabled .
C-STATE Tech
If enabled, C-State is set by the system automatically to either C2, C3 or C4 state.
The options are Disabled and Enabled .
C-State package limit setting
If set to Auto, the AMI BIOS will automatically set the limit on the C-State package
register. The options are Auto , C1, C3, C6 and C7.
C1 Auto Demotion
When enabled, the CPU will conditionally demote C3, C6 or C7 requests to C1 based
on un-core auto-demote information. The options are Disabled and Enabled.
C3 Auto Demotion
When enabled, the CPU will conditionally demote C6 or C7 requests to C3 based
on un-core auto-demote information. The options are Disabled and Enabled.
