Description
The HPE R4S28A is a high-density 64GB LRDIMM memory module engineered to meet the demanding requirements of modern enterprise environments. Operating at a speed of 2933MHz, it provides significant bandwidth, crucial for memory-intensive applications such as virtualization, large databases, and high-performance computing. The LRDIMM design helps to reduce the electrical load on the memory controller, allowing for higher memory capacities and improved stability in systems with many memory modules installed. With a 4Rx4 rank configuration, this module utilizes four ranks of memory chips, each organized with four bits per chip. This configuration offers a balance of density and performance, contributing to the overall efficiency of data access. The CL21 CAS latency indicates the number of clock cycles required for the memory to respond to a request, which is a standard latency for DDR4 modules of this speed and type. This memory is specifically validated for use with HPE ProLiant servers, ensuring compatibility and optimal performance. This 64GB DDR4-2933MHz LRDIMM is an ideal upgrade for servers requiring increased memory capacity and faster data throughput. It supports error correction code (ECC) functionality, which is vital for maintaining data integrity in critical server operations. By providing a robust and reliable memory solution, the R4S28A contributes to the overall stability and performance of the server infrastructure, enabling businesses to run their applications more efficiently and effectively.
