Product Description
The Samsung M386B4G70DM0-CMA40 is a high-capacity 32GB Registered DIMM (RDIMM) memory module, built using DDR3 SDRAM technology. This module is specifically designed for server and workstation environments where large amounts of memory are required for demanding applications, virtualization, and complex data processing. The RDIMM form factor includes a register chip that buffers memory commands and addresses, reducing electrical load on the memory controller and allowing for higher memory capacities and improved stability in multi-processor systems. Operating at a speed of 1866MHz (also known as PC3-14900), this memory module provides excellent performance for memory-intensive tasks. The CAS Latency (CL) of 13 indicates the number of clock cycles required to access a particular column of data, contributing to the overall responsiveness of the system. The 4Rx4 rank configuration signifies that the module has four ranks, each with x4 data width, which can offer advantages in certain memory controller designs for increased bandwidth and efficiency. Furthermore, the M386B4G70DM0-CMA40 incorporates Error-Correcting Code (ECC) functionality. ECC memory can detect and correct common types of internal data corruption, significantly enhancing data integrity and system reliability, which is critical for mission-critical server operations. With its substantial capacity, high speed, and robust features, this Samsung memory module is a suitable choice for upgrading or populating servers that require dependable and high-performance memory solutions.
