Coprocessor C1 state gates clocks on a core-by-core basis, reducing core power. On the
active SKU, the fan slows to an appropriate speed, reducing fan power. If all cores enter
C1, the coprocessor automatically enters Auto-pC3 state.

If clock-enable input to memory is pulled high, then memory enters M1 state which
reduces memory power.
