Micron MT9HTF12872Y-667EZES 1GB DDR2-667MHz RDIMM 1Rx4 CL5 Memory

Product Description

This Micron memory module, identified by the part number MT9HTF12872Y-667EZES, is a 1GB DDR2 SDRAM module engineered for server and workstation environments. It operates at a frequency of 667MHz, corresponding to a PC2-5300 speed rating, ensuring efficient data throughput. The module is a Registered DIMM (RDIMM), which incorporates a register chip to buffer command and address signals. This buffering mechanism reduces the electrical load on the memory controller, enabling support for higher memory capacities and enhancing overall system stability. The module is configured as 1Rx4 (Single Rank, x4 data width), meaning it consists of memory chips organized into a single rank with a 4-bit data interface per chip. This specific organization can impact performance characteristics in certain server architectures. Importantly, it supports ECC (Error-Correcting Code) functionality, which is critical for server-grade hardware. ECC detects and corrects single-bit memory errors, significantly improving data integrity and system reliability, which is vital for uninterrupted operation of critical applications. With a CAS Latency (CL) of 5, this DDR2 RDIMM provides a balance between speed and timing. The combination of 667MHz speed, RDIMM architecture, ECC support, and 1Rx4 organization makes the MT9HTF12872Y-667EZES a suitable component for upgrading or populating memory in compatible server platforms that demand robust, stable, and error-corrected memory performance.
