Abstract
An information handling system includes a DDR5 DIMM and a voltage regulator. The voltage regulator provides a voltage rail to the DDR5 DIMM. In a first mode, the voltage rail is based upon a pulse frequency modulation, and in a second mode, the voltage rail is based upon a forced continuous conduction mode). Selection of one of modes is based upon an input to the voltage regulator. When the information handling system is in a first state, the information handling system provides an input signal to the input to direct the voltage regulator to operate in the first state, and when the information handling system is in a second state associated with a sleep mode of the information handling system, the information handling system provides the first input signal to the first input of the voltage regulator to direct the voltage regulator to operate in the second state.
