Product Description
The Hynix HMT42GR7MFR4A-PBT8-AG is a high-density 16GB memory module designed for server and workstation environments that demand robust performance and stability. It utilizes DDR3 technology, operating at a clock speed of 1600MHz, which translates to a theoretical maximum bandwidth of 12.8GB/s per module (PC3-12800). The CAS Latency (CL) of 11 indicates the number of clock cycles required to access data, providing a balance between speed and efficiency for demanding applications. This module is a Registered DIMM (RDIMM), which includes an onboard register chip that buffers command and address signals. This buffering reduces the electrical load on the memory controller, allowing for higher memory capacities and improved signal integrity, especially in systems populated with multiple DIMMs. The 2Rx4 configuration signifies that the module has two ranks of memory chips, each organized with four data lines (x4). This dual-rank design can offer performance benefits in certain memory access patterns compared to single-rank modules. Furthermore, this Hynix RDIMM supports ECC (Error-Correcting Code) functionality. ECC memory can detect and correct common types of internal data corruption, significantly enhancing system reliability and data integrity. This makes the HMT42GR7MFR4A-PBT8-AG an ideal choice for mission-critical applications, virtualization, large databases, and scientific computing where data accuracy and uptime are paramount. It is compatible with motherboards and chipsets that support DDR3 1600MHz RDIMMs.
