IBM M396T2953EZ4-CE6M3 1GB DDR2-667MHz RDIMM 2Rx8 CL5 Memory

Product Description

The IBM M396T2953EZ4-CE6M3 is a 1 Gigabyte Registered Dual In-line Memory Module (RDIMM) utilizing DDR2 SDRAM technology. DDR2 memory offered improvements over DDR1, including higher clock speeds and lower operating voltages, while maintaining compatibility through distinct physical notches on the DIMM connector to prevent incorrect insertion. RDIMMs are specifically designed for server applications, featuring onboard registers that buffer command and address signals, which helps to reduce electrical load on the memory controller and allows for greater memory capacity and stability. This module operates at a speed of 667MHz (also known as PC2-5300), providing a good balance of performance for memory-intensive server tasks. The CAS Latency of CL5 indicates the number of clock cycles required to access data, which is a key performance metric. The 2Rx8 rank configuration signifies that the module contains two ranks of memory chips, each organized with eight data lines per chip. Dual-rank modules can sometimes offer performance benefits in certain server architectures due to how the memory controller accesses data. This IBM RDIMM is intended for use in servers that support DDR2 memory. It is crucial to ensure system compatibility, as DDR2 is not backward or forward compatible with other DDR generations. The M396T2953EZ4-CE6M3 serves as a reliable component for upgrading or populating memory in compatible server platforms, contributing to improved system performance and multitasking capabilities.
