Product Description
The Hynix HMT42GR7DFR4A-PBT4 is a 16GB DDR3 Registered DIMM (RDIMM) memory module, engineered to deliver high performance and reliability for server and workstation environments. Its substantial 16GB capacity is ideal for running demanding applications, supporting virtualization, managing large databases, and performing complex computations where significant memory resources are required for optimal operation. This module operates at a speed of 1600MHz, providing a PC3-12800 data transfer rate that ensures efficient data access and processing. The Registered DIMM (RDIMM) architecture includes an onboard register that buffers command and address signals, reducing the electrical load on the memory controller. This design enhances system stability, particularly in systems populated with multiple memory modules, and allows for higher overall memory capacities. The 2Rx4 rank configuration indicates two ranks of memory chips, each with a 4-bit data width per chip, contributing to its performance characteristics. The CAS Latency (CL) of 11 is optimized for the 1600MHz operating frequency, ensuring timely data retrieval. Crucially, this memory module features ECC (Error-Correcting Code) functionality, which is essential for detecting and correcting single-bit memory errors in real-time. This capability is vital for maintaining data integrity and ensuring the continuous operation of mission-critical server systems.
