Description

This 32GB DDR4 Load-Reduced DIMM (LRDIMM) from Samsung, identified by the SKU M386A4K40BB0-CRC4Y, is engineered for high-density server and workstation environments that demand significant memory capacity and performance. Operating at a speed of 2400MHz (PC4-19200), it provides ample bandwidth for memory-intensive applications such as large databases, virtualization, and scientific computing. The dual-rank (2Rx4) configuration allows for more efficient utilization of the memory bus by interleaving access between ranks, further boosting performance. The key characteristic of an LRDIMM is its inclusion of a memory buffer chip. Unlike RDIMMs which buffer command and address signals, LRDIMMs buffer all signals (command, address, and data). This significantly reduces the electrical load on the memory controller, enabling systems to support much higher memory capacities and more DIMMs per channel than would be possible with standard RDIMMs or UDIMMs. This makes LRDIMMs the preferred choice for servers requiring maximum memory expansion. With support for Registered ECC (Error-Correcting Code), this module ensures high levels of data integrity and system reliability, essential for mission-critical server operations. The module operates at a standard DDR4 voltage of 1.2V and has a CAS Latency of CL17. The M386A4K40BB0-CRC4Y is a robust solution for scaling server memory capacity while maintaining performance and stability.
