ABSTRACT:
A system and method for managing power consumption of an information handling system dynamically switches between high and low clock speed data transfers with double data rate (DDR) memory. The selection of a high clock speed dynamically switches the DDR memory to connect to a parallel termination for more rapid data transfers with increased power consumption. The selection of a low clock speed dynamically switches the DDR memory to disconnect the parallel termination for slower data transfers with reduced power consumption. In one embodiment, portable computer graphics DDR memory reduces power consumption by selecting low clock speed transfers without parallel termination when operating on internal power. The portable computer graphics DDR memory provides improved display resolution by selecting high clock speed transfers with parallel termination when operating on external power or when displaying information from high resolution applications.
