Product Description
The Micron MT36RTF51272FY-667GZD6ES is a 4GB DDR2 Fully Buffered DIMM (FB-DIMM) memory module, designed to provide high memory bandwidth and density for server platforms. Operating at a frequency of 667MHz (PC2-5300F), this module utilizes an Advanced Memory Buffer (AMB) chip, which serializes data traffic between the memory controller and the DRAM chips. This buffering mechanism significantly reduces the electrical load on the memory controller, enabling systems to support a much larger number of memory modules and higher total memory capacities compared to traditional Registered DIMMs. This specific FB-DIMM is configured as 2Rx4, meaning it is dual-rank and uses x4 (4-bit) DRAM devices. The CAS Latency (CL) is rated at 6, indicating the number of clock cycles required to access data after a command is issued. FB-DIMMs were a key technology for scaling server memory in the DDR2 era, offering a path to terabytes of RAM in high-end systems, albeit with slightly higher latency due to the buffering. Ideal for servers that require maximum memory capacity and bandwidth, such as those used for virtualization, large databases, or high-performance computing, the MT36RTF51272FY-667GZD6ES provides a robust solution. Its FB-DIMM architecture ensures system stability even with a large number of memory modules installed, making it a critical component for dense server configurations.
