Product Description
The Hynix HMT42GR7CMR4A-G7D3AF is a high-performance 16GB DDR3 Registered DIMM (RDIMM) memory module, specifically engineered for demanding server and workstation applications. Operating at a speed of 1066MHz (often referred to as PC3-8500), this module provides substantial bandwidth crucial for memory-intensive tasks. The 4Rx4 configuration signifies a quad-rank design with x4 data width per rank, which can enhance performance and efficiency in systems that support it, particularly in high-density memory configurations. This RDIMM incorporates Error-Correcting Code (ECC) functionality, which is essential for maintaining data integrity in critical server environments. ECC memory can detect and correct common types of internal data corruption, thereby reducing the risk of system crashes and data loss. The CAS Latency (CL) of 7 further contributes to its performance characteristics, indicating the number of clock cycles required to access data from the memory module. This combination of speed, capacity, and error correction makes it a reliable choice for mission-critical computing. Designed for compatibility with server-grade motherboards and chipsets, the HMT42GR7CMR4A-G7D3AF is a key component for upgrading or building systems that require robust and stable memory performance. Its specifications are tailored to meet the needs of virtualization, database management, scientific computing, and other applications that rely heavily on memory resources. Hynix is a well-respected manufacturer in the memory industry, known for producing high-quality and reliable memory modules.
