Micron MT36HTF51272FDY-667EZN8ES 4GB DDR2-667MHz FB-DIMM 4Rx8 Memory

Description

The Micron MT36HTF51272FDY-667EZN8ES is a 4GB DDR2 Fully Buffered DIMM (FB-DIMM) memory module. It operates at a speed of 667MHz, corresponding to the PC2-5300 standard, and features a quad-rank (4Rx8) configuration. FB-DIMMs were designed for server environments to overcome the limitations of traditional DIMMs by introducing an Advanced Memory Buffer (AMB) chip on each module. This buffer serializes data, reducing the electrical load on the memory controller and enabling higher memory densities and speeds. The quad-rank design means the module has four independent sets of memory chips, allowing the memory controller to access different ranks, potentially improving performance in systems that can leverage this architecture. The CL5 (CAS Latency 5) timing indicates the number of clock cycles for data retrieval. This module operates at a standard voltage of 1.8V for DDR2 FB-DIMMs and includes ECC (Error-Correcting Code) functionality, which is critical for maintaining data integrity in mission-critical server applications. This specific module is intended for servers and high-end workstations that utilize the FB-DIMM form factor, which is physically larger than standard DIMMs and requires specific motherboard support. The 'ES' suffix in the part number might indicate an engineering sample or a specific revision, but the core technical specifications remain consistent with a 4GB DDR2-667MHz FB-DIMM.
