Samsung M393B2G70DB0-CMAQ2 16GB DDR3-1866MHz RDIMM 2Rx4 CL13 Memory

Product Description

The Samsung M393B2G70DB0-CMAQ2 is a high-capacity 16GB memory module engineered for server and workstation applications where stability, performance, and reliability are paramount. It utilizes DDR3 SDRAM technology, operating at a frequency of 1866MHz, which corresponds to a PC3-14900 designation, providing substantial bandwidth for data-intensive tasks. The module is a Registered DIMM (RDIMM), meaning it incorporates a register chip that buffers command and address signals, reducing electrical load on the memory controller and allowing for higher memory capacities and improved stability in multi-module configurations. The 2Rx4 organization indicates that the module is dual-ranked, with each rank composed of memory chips organized in a x4 (4-bit wide) configuration. This architecture can offer performance benefits in certain server workloads by allowing the memory controller to access different ranks concurrently. The CAS Latency (CL) of 13 signifies the number of clock cycles required for the memory to respond to a column-address command, contributing to the overall timing characteristics of the memory subsystem. This Samsung memory module is designed to support Error-Correcting Code (ECC) functionality, a critical feature in server environments that detects and corrects single-bit memory errors, thereby preventing data corruption and system crashes. With its combination of high capacity, speed, registered architecture, and ECC support, the M393B2G70DB0-CMAQ2 is an ideal choice for upgrading or populating memory in enterprise-grade servers, high-performance computing systems, and workstations that demand robust memory performance.
