Power Management
There is no change to the signals driven by the processor to the DIMMs during DDR IO
EPG mode.

During EPG mode, all the DDR IO logic will be powered down, except for the Physical
Control registers that are powered by the un-gated V

power supply.
Unlike S3 exit, at DDR EPG exit, the DDR will not go through training mode. Rather, it
will use the previous training information retained in the physical control registers and
will immediately resume normal operation.

PCI Express* Power Management
• Active power management support using L0s and L1 states.
• All inputs and outputs disabled in L2/L3 Ready state.
• All inputs and outputs disabled in L2/L3 Ready state.
Note:
PCIe* interface does not support Hot-Plug.
Note:
An increase in power consumption may be observed when PCIe Active State Power
Management (ASPM) capabilities are disabled.

Rapid Memory Power Management (Intel
®
RMPM)
(also known as CxSR)
The Intel Rapid Memory Power Management (Intel RMPM) puts rows of memory into
self-refresh mode during C3/C6/C7 to allow the system to remain in the lower power
states longer. Processors routinely save power during runtime conditions by entering
the C3, C6, or C7 state. Intel RMPM is an indirect method of power saving that can
have a significant effect on the system as a whole.

Graphics Performance Modulation Technology
(Intel
®
GPMT)
Intel Graphics Power Modulation Technology (Intel
®
GPMT) is a method for saving
power in the graphics adapter while continuing to display and process data in the
adapter. This method will switch the render frequency and/or render voltage
dynamically between higher and lower power states supported on the platform based
on render engine workload. When the system is running in battery mode, and if the end
user launches applications such as 3D or Video, the graphics software may switch the
render frequency dynamically between higher and lower power/performance states
depending on the render engine workload.

In products where Intel
