Power Management—Processor

assertion with all pages closed). Pre-charge power-down provides greater power savings, but has a bigger performance impact since all pages will first be closed before putting the devices in power-down mode.

If dynamic power-down is enabled, all ranks are powered up before doing a refresh cycle and all ranks are powered down at the end of refresh.

4.3.2.4DRAM I/O Power Management

Unused signals should be disabled to save power and reduce electromagnetic interference. This includes all signals associated with an unused memory channel. Clocks, CKE, ODE, and CS signals are controlled per DIMM rank and will be powered down for unused ranks.

The I/O buffer for an unused signal should be tri-stated (output driver disabled), the input receiver (differential sense-amp) should be disabled, and any DLL circuitry related ONLY to unused signals should be disabled. The input path must be gated to prevent spurious results due to noise on the unused signals (typically handled automatically when input receiver is disabled).

4.3.3DRAM Running Average Power Limitation (RAPL)

RAPL is a power and time constant pair. DRAM RAPL defines an average power constraint for the DRAM domain. Constraint is controlled by the PCU. Platform entities (PECI or in-band power driver) can specify a power limit for the DRAM domain. PCU continuously monitors the extant of DRAM throttling due to the power limit and rebudgets the limit between DIMMs.

4.3.4DDR Electrical Power Gating (EPG)

The DDR I/O of the processor supports Electrical Power Gating (DDR-EPG) while the processor is at C3 or deeper power state.

In C3 or deeper power state, the processor internally gates VDDQ for the majority of the logic to reduce idle power while keeping all critical DDR pins such as SM_DRAMRST#, CKE and VREF in the appropriate state.

In C7, the processor internally gates VCCIO_TERM for all non-critical state to reduce idle power.

In S3 or C-state transitions, the DDR does not go through training mode and will restore the previous training information.

4.4PCI Express* Power Management

•Active power management is supported using L0s, and L1 states.

•All inputs and outputs disabled in L2/L3 Ready state.

4.5Direct Media Interface (DMI) Power Management

Active power management is supported using L0s/L1 state.
