Product Description
The Hynix HMA451R7MFR8N-TFTD-AA is a 4GB DDR4 Registered DIMM (RDIMM) memory module, engineered for modern server and workstation platforms. It operates at a speed of 2133MHz, offering improved bandwidth and efficiency compared to previous DDR generations. The Registered DIMM architecture includes an onboard register that buffers address and command signals, reducing the electrical load on the memory controller and enabling higher memory capacities and greater stability in systems with multiple DIMMs. This module features a CAS Latency (CL) of 15, which is the number of clock cycles required to access a specific column of data. The 1Rx8 configuration signifies that it is a single-rank module utilizing eight data chips per rank. Single-rank modules are common and provide a good balance of performance and cost-effectiveness for many server applications. The standard operating voltage for DDR4 memory is 1.2V, contributing to lower power consumption and heat generation compared to DDR3. As an ECC (Error-Correcting Code) memory module, the HMA451R7MFR8N-TFTD-AA is capable of detecting and correcting common internal data errors, which is critical for maintaining data integrity and system stability in mission-critical server environments. This makes it a reliable choice for applications such as virtualization, databases, and high-availability computing where data accuracy is paramount. The module's specifications make it compatible with a wide range of server motherboards that support DDR4 RDIMMs at 2133MHz.
