Samsung M393ABG40M5B-CYFCQ 256GB DDR4-2933MHz RDIMM 8Rx4 CL21 Memory

Product Description

This Samsung M393ABG40M5B-CYFCQ module represents a significant leap in memory density, offering a massive 256GB capacity. Built on the DDR4 standard, it operates at a speed of 2933MHz, providing substantial bandwidth crucial for data-intensive server workloads. The RDIMM form factor includes a register chip that buffers command and address signals, enabling higher memory capacities and improved signal integrity, which is essential for systems demanding extreme memory footprints. The module's 8Rx4 organization is particularly noteworthy, indicating an octal-rank design with x4 data width per DRAM chip. This configuration allows for maximum density within a single module and can offer performance benefits by enabling the system to access multiple ranks concurrently. The CAS Latency is CL21, which is typical for high-capacity, high-speed DDR4 modules, balancing performance with the complexities of managing such a large amount of memory. As an ECC (Error-Correcting Code) enabled module, it provides critical data integrity features necessary for enterprise-level operations. ECC functionality detects and corrects single-bit errors, significantly reducing the risk of data corruption and system crashes. This 256GB RDIMM is engineered for the most demanding server applications, including large-scale in-memory databases, high-performance computing (HPC), and extensive virtualization environments where maximum memory capacity and reliability are paramount.
