Abstract: A method of saving power in a computing system having a plurality of dual in-line memory modules (DIMMs) and employing a suspend-to-RAM sleep mode includes, when entering suspend-to-RAM sleep mode, consolidating (S130) selected information into a subset of DIMMs, and turning off (S150) power to all other DIMMs. A DIMM power rail (320) may be coupled to each of the DIMMs (310), the DIMM power rail being configured to selectively have power being supplied to respective DIMMs turned off in response to enable/disable logic signals.
