Intel® Rapid Memory Power Management (Intel® RMPM)
Intel® Rapid Memory Power Management (Intel® RMPM) conditionally places memory into self-refresh when the processor is in package C3 or deeper power state to allow the system to remain in the deeper power states longer for memory not reserved for graphics memory. Intel® RMPM functionality depends on graphics/display state (relevant only when processor graphics is being used), as well as memory traffic patterns generated by other connected I/O devices.
