Samsung Electronics announced on September 15 that it has developed DDR3 registered dual inline memory modules (RDIMMs) designed for use in low-power enterprise server systems at a 1.25 voltage.
Utilizing four-gigabit (4Gb) DDR3 components based on 30nm-class process technology, Samsung's new DDR3 modules deliver greener memory solutions for servers than 1.5 volts alternatives or the previous 1.35V version, while providing higher performance, the company said.
In case of a 1.25V 16GB RDIMM, the module consumes only 3.7 watts per hour, while operating at a bandwidth of up to 1.333Mbps. This is an approximate 15% power savings compared to a 1.35V 16GB RDIMM using 30nm-class 4Gb DDR3 chips, and an approximate 60% savings compared to a 1.35V 16GB RDIMM using 40nm-class 2Gb DDR3 chips.
Samsung plans to begin mass producing the modules in densities of four, eight and 16 gigabytes (GBs), after they are qualified with OEMs.
