Micron MT36HTF51272FDY-80EEZN8ES 4GB DDR2-800MHz FB-DIMM 4Rx8 Memory

Product Description

The Micron MT36HTF51272FDY-80EEZN8ES is a 4GB Fully Buffered DIMM (FB-DIMM) module utilizing DDR2 SDRAM technology. This type of memory was commonly used in servers and workstations that required high memory capacities and advanced features for reliability. The FB-DIMM architecture incorporates an Advanced Memory Buffer (AMB) chip on each module, which serializes data traffic between the memory controller and the DRAM chips, enabling higher densities and speeds compared to traditional Registered DIMMs (RDIMMs). Operating at a speed of 800MHz, this module provides substantial bandwidth for memory-intensive applications. The DDR2 standard itself offered improvements over DDR, and the FB-DIMM implementation further enhanced its capabilities for server environments. The 4Rx8 rank configuration signifies that the module contains four ranks, each composed of memory chips with an 8-bit data width, contributing to its overall capacity and performance characteristics. As an FB-DIMM, this module inherently supports ECC (Error-Correcting Code) functionality, which is critical for maintaining data integrity in server systems. ECC memory can detect and correct common types of internal data corruption, preventing system crashes and data loss. While FB-DIMMs have largely been superseded by DDR3 and DDR4 RDIMMs in newer systems due to power consumption and heat considerations, they remain a vital component for maintaining and upgrading older server infrastructure that relies on this specific memory technology.
