Product Description
The HP 726728-B21 is a 32GB DDR4 Registered DIMM (RDIMM) memory module designed for HP ProLiant servers and other compatible enterprise systems. It operates at a speed of 2133MHz, identified as PC4-17000R, and features a CAS Latency (CL) of 15, providing a good balance of performance for modern server workloads. The RDIMM architecture includes an onboard register that buffers command and address signals, reducing the load on the memory controller and enabling support for higher memory capacities and densities. This module is configured as 2Rx4, meaning it utilizes two ranks of memory chips, with each rank containing four data bits. This configuration is common for 32GB DDR4 modules and is optimized for performance in server environments. As a server-grade memory component, it incorporates Error-Correcting Code (ECC) functionality. ECC memory is critical for maintaining system stability and data integrity by detecting and correcting single-bit errors, which is essential for mission-critical applications and continuous operation. Operating at a standard voltage of 1.2V, the HP 726728-B21 offers improved power efficiency compared to previous DDR generations. Its combination of substantial capacity, high speed, ECC support, and specific compatibility with HP servers makes it a reliable choice for upgrading or populating memory in systems used for virtualization, databases, cloud computing, and other demanding business applications.
