RAM DDR2 2GB, PC667
DDR2 features optimize server performance
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.
FB DIMMs for maximum density
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. The FBDIMM architecture increases the memory channels to provide up to 21.2GB/ second of memory bandwidth.
powerful new RAS features
With system reliability so essential in servers as they take on an ever-greater workload, the FB DIMM architecture helps deliver exceptional reliability. Most notable is a silent data error rate of one per 100 years or less, enabled by a robust CRC scheme that protects both commands and data. Also boosting reliability are features such as transient bit-error detection and retry and “bit-lane fail-over correction.” This enables the server board to shut down a bad data path on the fly. Optional bit widths and CRC coverage will be applicable to a wide range of server applications.
world's highest-capacity server memory
SAMSUNG's most dense FB DIMM offering is an 8GB memory module that is the world's highestcapacity server memory solution. The module includes 32 2Gb stacked devices based on new technology, plus an Advanced Memory Buffer (AMB) that allows the memory modules to be daisy chained together across a two-way, point-to-point serial bus. The AMB also increases the data transfer speed between memory and CPUs, directly communicating with a memory controller chip. Whether for single- or dual-core processors or as add-on memory, SAMSUNG's large portfolio of the fully validated DDR2 products meets any needs for advanced server memory.
