Hynix HYMP564F72BP8N3-Y5-A 512MB DDR2-667MHz FB-DIMM 1Rx8 CL5 Memory

Product Description

The Hynix HYMP564F72BP8N3-Y5-A is a 512MB memory module utilizing DDR2 Synchronous Dynamic Random-Access Memory (SDRAM) technology. This module is specifically a Fully Buffered DIMM (FB-DIMM), characterized by the presence of an Advanced Memory Buffer (AMB) chip. The AMB chip serializes data transfers between the memory module and the memory controller, significantly reducing the electrical load on the controller. This design allows for higher memory capacities and speeds to be implemented in server systems, which often require extensive memory configurations. This module operates at a clock speed of 667MHz, corresponding to a PC2-5300F data rate, providing substantial bandwidth for demanding server applications. The inclusion of ECC (Error-Correcting Code) is a vital feature for server environments, as it enhances data integrity by detecting and correcting single-bit errors, thereby minimizing the risk of system crashes and data corruption. The 1Rx8 organization indicates a single rank of memory chips, each with an 8-bit data width. The CAS Latency (CL) for this module is CL5, which refers to the number of clock cycles it takes for the memory to respond to a column address command. While FB-DIMMs were a key technology for scaling server memory in the DDR2 era, they were eventually superseded by DDR3 RDIMMs and LRDIMMs due to power consumption and latency considerations. The HYMP564F72BP8N3-Y5-A is designed for servers that specifically support DDR2 FB-DIMMs, offering a reliable solution for memory-intensive tasks.
