Description
This 64GB DDR4 Registered DIMM (RDIMM) from Samsung, identified by SKU M393A8G40MB2-CTD6Y, represents a significant capacity upgrade for modern server platforms. Operating at a speed of 2666MHz (PC4-21300), it delivers high bandwidth essential for demanding enterprise workloads, virtualization, large databases, and complex data analytics. The module features a 2Rx4 configuration, meaning it is dual-ranked and utilizes x4 DRAM chips. This configuration can enhance performance by allowing the memory controller to access different ranks and chipsets more efficiently, particularly beneficial in systems with multiple memory modules. As an RDIMM, it includes onboard registers to buffer address and command signals, improving signal integrity and enabling higher memory densities and system stability. With a CAS Latency (CL) of 19, this DDR4 module is optimized for performance and reliability in server environments. It supports ECC (Error-Correcting Code) to detect and correct single-bit memory errors, ensuring data integrity and system uptime, which are critical for mission-critical applications. This memory is ideal for servers requiring substantial memory capacity and robust performance.
