Product Description
The Hynix HMT42GR7DFR4A-PBT4AD is a high-capacity 16GB DDR3 memory module designed to meet the demanding requirements of modern servers and workstations. Operating at a speed of 1600MHz (PC3-12800), it provides significant bandwidth for data-intensive tasks, virtualization, and large databases. The Registered DIMM (RDIMM) architecture includes an onboard register that buffers command and address signals, reducing the electrical load on the memory controller and enabling higher memory capacities and improved system stability, which is crucial for mission-critical applications. This module utilizes a 2Rx4 configuration, meaning it is dual-ranked with each rank composed of x4 DRAM devices. Dual-rank modules can offer performance advantages in certain scenarios by allowing the memory controller to access different ranks concurrently, effectively increasing the memory bus width for specific operations. The CAS Latency (CL) of 11 indicates the number of clock cycles required to access a specific column address, representing a balance between speed and stability for DDR3 memory at this frequency. Built by Hynix, a reputable manufacturer of memory components, this module is designed for reliability and sustained performance in 24/7 operating environments. It supports Registered ECC (Error-Correcting Code) functionality, which detects and corrects single-bit errors, preventing data corruption and ensuring system integrity. The standard 1.5V operating voltage is typical for DDR3 RDIMMs. This 16GB DDR3-1600MHz RDIMM is an excellent choice for upgrading existing server infrastructure or building new systems that require substantial and dependable memory resources.
