SAMSUNG’SGREEN DDR3 DELIVERSMAJOR ENERGY SAVINGS

Dual-and multi-core CPUs for multi-tasking activities, 64-bit operating systems and compute-intensive applications

such as virtualization, 3D, gaming and photo/video editing are accelerating the need for higher-performance memory

with reduced power consumption. From PCs to servers, Samsung’s 40nano-class Green DDR3 provides designers with

the key to creating the most energy-efficient, high-performance computing platforms available today.
