Description
This 32GB DDR4 RDIMM from Samsung, model M393A4K40BB1-CRC40, is a critical component for servers and workstations that handle intensive workloads. The substantial 32GB capacity is essential for running multiple virtual machines, managing large databases, or performing complex data analytics. DDR4 technology provides significant improvements in power efficiency and data throughput over previous DDR generations, making it a standard for modern high-performance computing. The 2Rx4 rank configuration means the module is dual-rank, with each rank composed of four memory chips. This design enhances performance by allowing the memory controller to interleave operations between the two ranks, increasing the effective bandwidth and reducing access times. This is particularly advantageous in server environments where memory performance directly impacts application responsiveness and overall system throughput. As a Registered DIMM (RDIMM), this module incorporates an onboard register that buffers address and command signals. This buffering reduces the electrical load on the memory controller, enabling systems to support a greater number of memory modules and higher total memory capacities without compromising signal integrity. The CL17 latency rating specifies the timing for data access, contributing to the module's overall performance profile in conjunction with its speed and rank configuration.
