Samsung M393B1K70DH0-CH9B 8GB DDR3-1333MHz RDIMM 2Rx4 CL9 Memory

Product Description

The Samsung M393B1K70DH0-CH9B is an 8GB DDR3 Registered DIMM (RDIMM) memory module, specifically designed for server and workstation environments where reliability and performance are critical. It operates at a speed of 1333MHz, providing ample bandwidth for memory-intensive tasks common in enterprise computing. The RDIMM design includes an onboard register that buffers command and address signals, reducing the electrical load on the memory controller and enabling higher memory capacities and improved system stability, especially in systems with multiple processors. This module features a CAS Latency (CL) of 9, which, combined with its 1333MHz clock speed, ensures efficient data access. The 2Rx4 configuration indicates a dual-rank module, where each rank utilizes four memory chips. Dual-rank modules can offer performance benefits in certain server architectures by allowing the memory controller to interleave access between ranks. The standard 1.5V operating voltage is typical for DDR3 memory modules. Crucially, this RDIMM supports ECC (Error-Correcting Code) functionality. ECC memory can detect and correct single-bit memory errors, significantly enhancing data integrity and system reliability, which is paramount for mission-critical server operations. Before installation, it is essential to confirm that the target server or workstation motherboard and CPU support DDR3 RDIMMs and ECC memory to ensure proper functionality and compatibility.
