Micron MT36RTF51272FDZ-667HZD6ES 4GB DDR2-667MHz FB-DIMM 2Rx4 Memory

Product Description

This Micron memory module, identified by SKU MT36RTF51272FDZ-667HZD6ES, is a 4GB DDR2 Fully Buffered DIMM (FB-DIMM) operating at a frequency of 667MHz. FB-DIMMs were a transitional technology designed to overcome the electrical limitations of traditional DIMMs in high-density memory configurations, particularly in multi-processor systems. They feature an Advanced Memory Buffer (AMB) chip on each module, which serializes data traffic, reducing the electrical load on the memory controller and allowing for higher memory capacities and speeds. The 2Rx4 designation signifies a dual-rank configuration with four data bits per DRAM chip. Dual-rank modules can offer performance benefits by allowing the memory controller to access different ranks independently, potentially improving efficiency. The x4 organization indicates that each DRAM chip on the module is designed to handle 4 bits of data per clock cycle. This specific configuration is optimized for servers and workstations that require substantial memory bandwidth and capacity for memory-intensive tasks such as virtualization, large database operations, and scientific computing. With its ECC capabilities, the MT36RTF51272FDZ-667HZD6ES can detect and correct single-bit memory errors, enhancing system stability and data integrity, which is crucial in mission-critical server environments. The 667MHz speed, also known as PC2-5300F, provides a theoretical peak bandwidth of 5.3GB/s per module, contributing to overall system responsiveness and performance. This module is an ideal upgrade or replacement for systems that support DDR2 FB-DIMM technology.
