Hynix HYMP564F72CP8D3-Y5-A 512MB DDR2-667MHz FB-DIMM 1Rx8 CL5 Memory

Description

The Hynix HYMP564F72CP8D3-Y5-A is a 512MB memory module based on DDR2 Synchronous Dynamic Random-Access Memory (SDRAM) technology. This module is a Fully Buffered DIMM (FB-DIMM), which incorporates an Advanced Memory Buffer (AMB) chip. The AMB chip serializes data transfers, reducing the electrical load on the memory controller and enabling higher memory capacities and densities in server systems. This design was crucial for scaling memory in the DDR2 generation of servers. Operating at a frequency of 667MHz (PC2-5300F), this module provides a substantial data transfer rate suitable for various server workloads. The inclusion of ECC (Error-Correcting Code) is a standard and critical feature for server memory, as it enhances data integrity by detecting and correcting single-bit errors, thereby preventing system instability and data corruption. The 1Rx8 memory organization signifies a single rank of memory chips, each with an 8-bit data width. The CAS Latency (CL) for this module is CL5, indicating the number of clock cycles required for the memory to respond to a column access command. While FB-DIMMs offered advantages in density and controller load, they also introduced higher latency and power consumption compared to later memory technologies like DDR3 RDIMMs. The HYMP564F72CP8D3-Y5-A is designed for servers that specifically support DDR2 FB-DIMM memory, providing a reliable and high-capacity memory solution for demanding enterprise applications.
