Product Description
The HP 516424-S21 is a high-performance 8GB DDR3 Registered DIMM (RDIMM) memory module engineered for robust server and workstation applications. Operating at a frequency of 1066MHz, it delivers efficient data processing capabilities suitable for memory-intensive tasks. The RDIMM architecture incorporates onboard registers that buffer command and address signals, reducing the electrical load on the memory controller and enhancing system stability, particularly in systems with multiple memory modules installed. This makes it a reliable choice for enterprise environments demanding consistent uptime. This module features a 2Rx4 configuration, indicating it is dual-ranked with four data bits per DRAM chip. This dual-rank design can offer performance advantages by allowing the memory controller to interleave access between ranks, potentially increasing bandwidth and improving efficiency in certain operational scenarios. Furthermore, the inclusion of Error-Correcting Code (ECC) is a critical feature for server-grade memory. ECC technology detects and corrects single-bit errors on the fly, significantly reducing the risk of data corruption and system crashes, thereby ensuring data integrity and system reliability. With a CAS Latency (CL) of 7, the 516424-S21 provides a low latency response time, contributing to overall system responsiveness. The standard 1.5V operating voltage ensures compatibility with a wide array of DDR3-compatible server platforms. This 8GB RDIMM module is an essential component for upgrading or expanding the memory capacity of HP ProLiant servers and other compatible enterprise systems, enabling enhanced performance for virtualization, databases, and other demanding workloads.
