Abstract: A system and method are provided wherein the voltage to a random access memory system may be automatically, dynamically adjusted without requiring an operating system to be restarted. In one embodiment, a target value of a voltage supplied to the memory system is dynamically selected. A system management mode is invoked in response to a change in the dynamically selected target value, including suspending a normal operation of the memory system. While in the system management mode, the voltage supplied to the memory system is adjusted according to the changed target voltage. A memory speed is adjusted according to the changed target value of the voltage. These steps are performed without restarting the computer system. The system management mode is exited and normal operation of the memory system may resume at the changed target voltage.

Abstract: A design structure embodied in a machine readable storage medium for of designing, manufacturing, and/or testing a design is provided. The design structure includes an apparatus for setting a reference voltage for a bus agent. The apparatus includes a computer processor, a computer memory, with computer program instructions disposed within it, operatively coupled to the computer processor. The computer program instructions are capable of identifying a present configuration of a bus, and identifying a reference voltage value for each bus agent connected to the bus. The apparatus further includes means for applying a reference voltage to each bus agent in dependence upon an identified reference voltage value for each bus agent.
