HP 74407S 16GB DDR3-1066MHz ECC Registered CL7 RDIMM 4R Memory Module

Product Description

The HP 74407S is a high-capacity 16GB DDR3 ECC Registered DIMM (RDIMM) memory module, engineered for server environments where reliability and performance are critical. Operating at a frequency of 1066MHz, it provides a stable platform for running demanding server applications, databases, and virtualization tasks. The Registered DIMM design incorporates a register chip that buffers command and address signals, reducing the electrical load on the memory controller. This allows for higher memory capacities and improved system stability, particularly in multi-processor configurations. This module features a CAS Latency (CL) of 7, which is relatively low for its speed, indicating good responsiveness. The 4R designation signifies that the module is quad-ranked. Quad-rank modules can offer significant performance benefits in certain server architectures by allowing the memory controller to interleave access across multiple ranks, effectively increasing bandwidth and reducing latency. This advanced configuration is typically found in high-end servers designed for maximum memory throughput. As an ECC (Error-Correcting Code) module, the 74407S is equipped to detect and correct single-bit memory errors, which is essential for preventing data corruption and system crashes in mission-critical server operations. This makes it an ideal choice for environments such as data centers, financial institutions, and research facilities where data integrity is non-negotiable. Compatibility with specific server models should always be verified.
