The need for increased server performance is unrelenting, thus DDR2 SDRAM has taken its place as the high-density standard for server main memory. Its advanced architecture gives DDR2 a host of advantages over earlier standards, such as faster speeds, better signal integrity, lower power consumption and better thermal characteristics.
In addition to DDR2 registered DIMMs for servers, Samsung is offering Fully Buffered DIMMs (FBDIMMs) so servers can benefit from the highest possible memory density and bandwidth. Servers equipped with FBDIMMs can get up to 16 gigabytes per channel of total system memory. This advanced server memory architecture buffers the DRAM data pins from the channel and uses point-to-point links to eliminate the need for a stub bus. The buffers and repeaters help reduce the motherboard routing area. This architecture requires one-third fewer pins than registered DIMMs and also delivers excellent throughput and low latency.
