Product Description
The Samsung M393ABG40M52-CYFG0 is a massive 256GB DDR4 Registered DIMM (RDIMM) designed for the most demanding enterprise server and data center applications. Operating at a high frequency of 2933MHz, this module significantly accelerates data transfer rates and improves overall system performance, crucial for memory-intensive workloads such as large-scale virtualization, in-memory databases, and high-performance computing (HPC). The RDIMM form factor includes a register chip that buffers command and address signals, reducing electrical load on the memory controller and allowing for higher memory capacities and densities. This module boasts an 8Rx4 rank configuration, meaning it utilizes eight ranks of memory chips, each organized as four data bits. This high rank count, combined with the DDR4 technology, allows for exceptional bandwidth and efficient utilization of the memory bus. Furthermore, as an RDIMM, it inherently supports Error-Correcting Code (ECC) functionality, which detects and corrects single-bit memory errors, thereby enhancing system reliability and data integrity – a critical requirement for mission-critical server environments. The M393ABG40M52-CYFG0 is engineered for compatibility with servers that specifically support DDR4-2933MHz RDIMMs. Its substantial 256GB capacity per module allows for the creation of systems with terabytes of RAM, enabling advanced data analytics, complex simulations, and the consolidation of numerous virtual machines onto a single physical server. This memory solution from Samsung represents a pinnacle of performance, capacity, and reliability for modern enterprise infrastructure.
