Product Description
The Samsung M393A8K40B21-CRB00 is a high-capacity 64GB DDR4 Registered DIMM (RDIMM) memory module. Engineered for demanding server and workstation environments, this module operates at a frequency of 2133MHz, providing a significant boost in data processing capabilities. The RDIMM form factor includes registers that buffer command and address signals, reducing electrical load on the memory controller and allowing for higher memory capacities and improved stability in multi-module configurations. This memory module features a CAS Latency (CL) of 15, indicating the number of clock cycles required to access data. Its 4Rx4 rank organization signifies that the module is composed of four ranks, each with an 8-bit data width (effectively 4 x 8-bit = 32-bit data path per rank, which is then combined). This configuration is common in high-density server memory modules and contributes to its overall performance. Furthermore, it supports ECC (Error-Correcting Code) functionality, which detects and corrects single-bit errors, crucial for maintaining data integrity in critical applications. With its substantial capacity, efficient speed, and robust error correction capabilities, the Samsung M393A8K40B21-CRB00 is an ideal choice for memory-intensive applications such as large databases, virtualization, scientific simulations, and high-performance computing. It is designed to enhance the overall performance, reliability, and stability of server systems that require large amounts of memory.
