Description
This Hynix HMA42GR7BJR4N-TFTDAA is a 16GB DDR4 Registered DIMM (RDIMM), designed to provide substantial memory capacity for demanding server and workstation environments. Operating at a frequency of 2133MHz (PC4-17000), it meets the performance requirements for many enterprise-grade applications. The Registered DIMM architecture helps to improve signal integrity and allows for higher memory densities, which is critical for systems that need to support large amounts of RAM. The module features a CAS Latency of CL15, offering a responsive performance profile for its speed class. The 2Rx4 configuration indicates that it is a dual-ranked module with four data bits per DRAM chip. Dual-ranked modules can sometimes offer performance advantages in certain memory controller architectures by allowing for more efficient interleaving, though they also place a slightly higher load on the memory controller compared to single-ranked modules. As a DDR4 memory component, it benefits from the advancements in memory technology, including higher bandwidth, improved power efficiency, and increased density over previous DDR generations. The inclusion of ECC (Error-Correcting Code) is a standard and essential feature for server memory, ensuring data integrity by detecting and correcting memory errors, thereby enhancing system reliability and preventing data corruption. This makes the HMA42GR7BJR4N-TFTDAA a robust choice for critical computing tasks.
