2 Features Optimize Server Performance The need for increased server performance is unrelenting, thus DDR
2 SDRAM has taken its place as the high-density standard for server main memory. Its advanced architecture gives DDR
2 a host of advantages over earlier standards, such as faster speeds, better signal integrity, lower power consumption and better thermal characteristics. With the industry's broadest product selection,
Samsung offers DDR
2 as both registered and fully buffered modules in densities up to 8
GB and in a range of speeds and configurations to support the needs of performance-conscious users. Many of DDR
2's key features are optimal for servers. For example, DDR
2's higher-density memory capabilities produce 20% higher peak bandwidth and support twice the data transfer rate of DDR333. Another DDR
2 advantage is increased memory support because DDR
2 allows up to four modules per channel compared to three with DDR. In addition, the 38% lower power consumption and reduced heat of DDR
2 are ideal for blade and rack servers where air flow may be limited. FB DIMMs for Maximum Density In addition to DDR
2 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. The FBDIMM architecture increases the memory channels to provide up to 21.2GB/ second of memory bandwidth.
