Samsung M393A4K40BB1-CRC 32GB DDR4-2400MHz RDIMM 2Rx4 CL17 Memory

Product Description

The Samsung M393A4K40BB1-CRC is a high-capacity 32GB DDR4 Registered DIMM (RDIMM) module, specifically designed for demanding enterprise server and workstation applications. It operates at a speed of 2400MHz, identified by the PC4-2400T standard, offering substantial improvements in bandwidth and efficiency over previous DDR generations. This makes it ideal for memory-intensive tasks such as large-scale data analytics, complex virtualization environments, and high-performance computing. The module features a CAS Latency (CL) of 17. While the latency is higher than some DDR3 modules, the increased clock speed and architectural improvements of DDR4 contribute to superior overall performance. The 2Rx4 configuration signifies a dual-rank module, where each rank uses x4 (4-bit) DRAM chips. Dual-rank modules can enhance performance by allowing the memory controller to interleave access between ranks, potentially increasing data throughput and system responsiveness. As a standard RDIMM, this memory module includes an onboard register that buffers command and address signals. This buffering reduces the electrical load on the memory controller, enabling servers to support a larger number of DIMMs and achieve higher total system memory capacities. Furthermore, RDIMMs are essential for server environments due to their support for ECC (Error-Correcting Code) functionality. ECC detects and corrects single-bit memory errors, which is critical for maintaining data integrity and system stability in mission-critical applications. The module operates at the lower DDR4 voltage of 1.2V, contributing to improved power efficiency.
