Product Description
This 16GB DDR2 Registered DIMM (RDIMM) from Micron is a high-density memory module designed for server and workstation environments where data integrity and stability are paramount. The DDR2 technology represents an older generation of RAM, but RDIMMs are still utilized in specific server platforms that require ECC (Error-Correcting Code) functionality. ECC memory can detect and correct common types of internal data corruption, significantly reducing the risk of system crashes and data loss. The module operates at a clock speed of 667MHz, corresponding to a PC2-5300 data transfer rate. The 'RDIMM' designation indicates that it includes a register chip that buffers the data signals between the memory controller and the DRAM chips. This buffering reduces electrical load on the memory controller, allowing for more memory modules to be installed per channel and enabling higher overall system memory capacities. The 4R x 4 organization signifies that the module is composed of four ranks, with each rank using DRAM chips that are 4 bits wide. This configuration is often used for higher density modules. With a CAS Latency (CL) of 5, the module has a specific timing characteristic that affects its performance. While DDR2 is a mature technology, modules like the MT72HTS2G72PY-667A1 are crucial for maintaining and upgrading older server infrastructure. It operates at a standard voltage of 1.8V, typical for DDR2 memory. This specific part number is essential for ensuring compatibility with motherboards and chipsets that explicitly support this configuration for optimal performance and reliability.
