Samsung Electronics has announced that it has developed DDR3 registered dual inline memory modules (RDIMMs) designed for use in low-power enterprise server systems with 1.25V voltage.
The new 16GB RDIMM is based on 4Gb memory modules made using 30nm process technology. The module consumes only 3.7W per hour, while operating at a bandwidth of up to 1333MHz. This is an approximate 15% power savings compared to a 1.35V 16GB RDIMM using 30nm-class 4Gb DDR3 chips, (which has been the module with the lowest power consumption at the same density until now), and an approximate 60% savings compared to a 1.35V 16GB RDIMM using 40nm-class 2Gb DDR3 chips.
“Our 1.25V RDIMM will add to an extremely robust memory portfolio for advanced enterprise server systems that are demanding higher energy efficiency from key components. We are contributing to a greener IT environment through the introduction of more innovative memory designs, while enhancing shared value throughout the server segment," said Wanhoon Hong, executive vice president, memory sales and marketing of device solutions at Samsung Electronics.
Samsung plans to begin mass producing the modules in densities of 4GB, 8GB and 16GB after they are qualified with OEMs. Starting next year, the 1.25V RDIMMs are expected to elicit a high degree of interest in data centers and enterprise server systems, where there is the most concern for reducing energy costs and improving efficiency.
