Product Description
This Hynix memory module, identified by SKU HMT42GR7AFR4A-PBT8, is engineered for high-performance computing environments where data integrity and speed are paramount. Its 16GB capacity provides ample room for complex datasets and multitasking, while the DDR3 technology ensures compatibility with a wide range of server platforms. The RDIMM configuration includes onboard registers to reduce electrical load on the memory controller, enabling higher densities and improved stability in systems with many memory modules. The module's 1600MHz clock speed translates to a theoretical bandwidth of 12.8GB/s, facilitating rapid data transfer between the memory and the CPU. The CL11 latency, while not the lowest, represents a standard for this generation of DDR3 memory, offering a practical compromise between speed and power consumption. The 2Rx4 organization indicates that the memory chips are arranged in two ranks, each with four data lines, further optimizing performance and efficiency. Designed for reliability in mission-critical applications, this memory module supports Error-Correcting Code (ECC), which detects and corrects single-bit errors on the fly, preventing data corruption and system crashes. This feature is essential for servers, workstations, and other systems where uptime and data accuracy are non-negotiable. The 240-pin DIMM form factor is standard for DDR3 RDIMMs, ensuring physical compatibility with appropriate motherboard slots.
