Description
The HP 839981-B21 is an 8GB DDR4 Registered DIMM (RDIMM) module, specifically designed to enhance the memory capacity and performance of compatible HP ProLiant servers and workstations. This module operates at a frequency of 2133MHz, offering a solid foundation for everyday business applications, light virtualization, and general server tasks. The 1Rx4 rank configuration signifies a single-rank design with an x4 data organization. This configuration is typically used in memory modules where a balance between capacity and performance is desired for specific server architectures. The module's CAS Latency (CL) is rated at 15, ensuring efficient response times for memory requests. As a Registered DIMM, the 839981-B21 includes an onboard register that buffers command and address signals, reducing the electrical load on the memory controller. This feature is crucial for system stability, especially when populating multiple memory slots. Furthermore, the module supports Error-Correcting Code (ECC), which is essential for detecting and correcting memory errors, thereby ensuring data integrity and system reliability in server environments. This 1.2V module is a cost-effective solution for basic memory upgrades.
