Product Description
The Kingston KSM48R40BD8TMM-32MAR is a high-capacity 32GB DDR5 RDIMM module engineered for advanced server and workstation platforms. This module utilizes a dual-rank (2Rx4) design, which means it has two independent sets of memory chips (ranks) accessible via a 4-bit data interface (x4). Dual-rank modules can offer improved performance in certain scenarios by allowing the memory controller to interleave access between the two ranks, effectively increasing the effective bandwidth and reducing latency under specific workloads. This makes it particularly suitable for memory-intensive applications and high-density server configurations. Operating at a robust 4800MHz frequency with a CAS Latency of CL40, this DDR5 module delivers substantial improvements in data throughput and responsiveness over previous generations. The RDIMM form factor includes onboard registers that buffer command and address signals, reducing the electrical load on the memory controller. This feature is critical for maintaining signal integrity and enabling higher memory capacities and speeds in systems with multiple memory modules, ensuring stability and reliability in demanding enterprise environments. As a component designed for mission-critical systems, the KSM48R40BD8TMM-32MAR is expected to incorporate advanced Error-Correcting Code (ECC) functionality. ECC memory detects and corrects single-bit errors on the fly, preventing data corruption and system crashes, which is indispensable for servers handling sensitive data or performing continuous operations. The DDR5 standard's inherent architectural enhancements, such as improved power management and increased burst lengths, further contribute to the module's overall efficiency and performance, making it an excellent choice for modern data centers and high-performance computing.
