Product Description
The Hynix HMA42GR7AFR4N-VKTF is a high-performance 16GB DDR4 Registered DIMM (RDIMM) memory module, engineered for robust server and workstation environments. It operates at a speed of 2666MHz, providing ample bandwidth for data-intensive tasks. The RDIMM design incorporates a register chip that buffers command and address signals, reducing the electrical load on the memory controller and enabling higher memory capacities and improved stability in systems populated with many DIMMs. This module is configured as 2Rx4, meaning it is dual-ranked with each rank consisting of DRAM chips that are 4 bits wide. Dual-rank modules can offer performance benefits in certain workloads by allowing the memory controller to interleave accesses between ranks, effectively increasing the memory bus efficiency. It also features ECC (Error-Correcting Code) support, which is essential for servers to detect and correct memory errors on the fly, thereby enhancing system reliability and data integrity. With a CAS Latency of CL19, this DDR4 RDIMM strikes a balance between speed and timing. The 288-pin connector ensures compatibility with modern server motherboards that support DDR4 memory. The combination of 16GB capacity, 2666MHz speed, ECC, and dual-rank architecture makes the HMA42GR7AFR4N-VKTF a suitable choice for demanding enterprise applications, virtualization, databases, and high-performance computing where memory capacity, speed, and reliability are critical.
