ATP AH28K72M4BHC4C 1GB DDR2-400MHz RDIMM 2Rx8 CL3 Memory

Product Description

The ATP AH28K72M48BHC4C is a 1GB DDR2 Registered DIMM (RDIMM) module designed for legacy server and workstation systems. It operates at a frequency of 400MHz, corresponding to the PC2-3200 standard. This module features a 2Rx8 configuration, indicating that it is dual-ranked, with each rank composed of memory chips that are 8 bits wide. Dual-rank modules can offer performance benefits by allowing the memory controller to interleave operations between the ranks, potentially improving efficiency in certain workloads. The module's CAS Latency (CL) is rated at CL3, signifying a low number of clock cycles required for data access. This timing characteristic is important for overall system performance, particularly in latency-sensitive applications. As an RDIMM, it incorporates an onboard register that buffers address and command signals, reducing the electrical load on the memory controller. This buffering is crucial for enabling higher memory capacities and ensuring system stability, especially in dense memory configurations common in servers. This 1GB DDR2 RDIMM also supports Error-Correcting Code (ECC) functionality. ECC memory is a standard feature in server environments as it can detect and correct single-bit errors and detect multi-bit errors, thereby enhancing system reliability and data integrity. While DDR2 is an older technology, modules like the AH28K72M48BHC4C are essential for maintaining existing infrastructure that relies on this specific memory standard.
