Description
The HP 74184S is a 4GB memory module engineered for enhanced reliability and data integrity, making it an ideal choice for server and workstation environments. It utilizes DDR3 SDRAM technology, operating at a speed of 1333MHz, which corresponds to a PC3-10600 designation. The module is an Unbuffered DIMM (UDIMM), meaning it does not have an onboard buffer chip, which is typical for standard server memory configurations. A key feature of this memory module is its ECC (Error-Correcting Code) capability. ECC memory can detect and correct common types of internal data corruption, significantly reducing the risk of system crashes and data loss that can occur with uncorrected memory errors. This makes it indispensable for applications where data accuracy and system stability are paramount, such as in critical business operations, scientific computing, and database management. With a CAS Latency of CL9 and a Dual Rank (2R) configuration, the 74184S offers a balance of performance and capacity for its generation. The 1.5V operating voltage is standard for DDR3 memory. This module is designed to meet the rigorous demands of enterprise computing, providing a dependable foundation for stable and efficient system operation.
