Micron MT36GTS1G72FY-667AZN8ES 8GB DDR2-667MHz FB-DIMM 2Rx4 CL5 Memory

Product Description

This Micron MT36GTS1G72FY-667AZN8ES module represents an 8GB DDR2 Fully Buffered DIMM (FB-DIMM), a memory technology primarily used in servers and workstations requiring high memory capacities and advanced signaling. Operating at a frequency of 667MHz, it offers a significant performance improvement over earlier DDR generations, though FB-DIMMs were later superseded by DDR3 and subsequent technologies due to power consumption and latency characteristics. The FB-DIMM architecture utilizes an Advanced Memory Buffer (AMB) chip on the module itself, which serializes data to and from the memory controller, reducing the number of parallel traces on the motherboard and enabling higher densities. The 2Rx4 configuration indicates that this module contains two ranks of memory chips, with each rank organized as x4 bits per chip. This dual-rank design allows the memory controller to interleave operations between the two ranks, potentially enhancing performance by increasing the effective bandwidth. The CAS Latency of CL5 specifies the number of clock cycles required to access a specific column address, a key timing parameter that influences memory responsiveness. This module also includes ECC (Error-Correcting Code) functionality, vital for server environments to detect and correct memory errors, thereby ensuring data integrity and system stability. Micron, a leading memory manufacturer, produces these FB-DIMMs to meet the demanding requirements of enterprise computing. The MT36GTS1G72FY-667AZN8ES is designed for systems that leverage the FB-DIMM interface for high-capacity memory configurations. While DDR2 FB-DIMMs are less common in new deployments, they remain essential for maintaining and upgrading existing server infrastructure that relies on this specific memory standard. The 8GB capacity per module allows for substantial total memory configurations in compatible systems.
