ATP AL56M7218BJH9S 2GB DDR3-1333MHz RDIMM 2Rx8 CL9 Memory

Product Description

The ATP AL56M7218BJH9S is a 2GB memory module that utilizes DDR3 SDRAM technology, designed for deployment in server and workstation environments. This module is an RDIMM (Registered DIMM), which means it incorporates a register chip that buffers the command and address signals sent from the memory controller. This buffering reduces the electrical load on the controller, enabling systems to support a greater number of memory modules and achieve higher overall memory capacities while maintaining stability. The RDIMM form factor is a standard for enterprise-grade systems where reliability and scalability are critical. This memory module operates at a frequency of 1333MHz, corresponding to a PC3-10600 designation, providing a solid balance of performance for a wide range of applications. It features a CAS Latency (CL) of 9, indicating the number of clock cycles it takes for the memory module to respond to a column address strobe command. The module's organization is specified as 2Rx8, meaning it is dual-rank and uses x8 (8-bit wide) DRAM chips. Dual-rank modules can sometimes offer performance advantages by allowing the memory controller to interleave access between ranks, though compatibility should always be verified with the system's specifications. Crucially, the AL56M7218BJH9S includes ECC (Error-Correcting Code) functionality. ECC memory is essential in server environments as it can detect and correct common types of internal data corruption, preventing system crashes and data loss that might occur with non-ECC memory. This makes it a reliable choice for critical applications and data-intensive tasks where data integrity is paramount. The 2GB capacity, while modest by today's standards, is suitable for upgrading older systems or for specific configurations where lower memory footprints are required.
