Product Description
This Hynix 32GB DDR3 Load-Reduced DIMM (LRDIMM), identified by SKU HMT84GL7MMR4A-H9M1AF, is engineered for server platforms that demand maximum memory capacity and performance. LRDIMMs utilize a memory buffer chip to reduce the electrical load on the memory controller, enabling higher memory configurations and densities than traditional RDIMMs. This makes them ideal for memory-intensive applications such as large-scale data analytics, virtualization hosts, and high-performance computing clusters. The module operates at a DDR3-1333MHz frequency, providing a solid data transfer rate suitable for a wide range of enterprise workloads. The CAS latency of CL9 signifies a low delay in data retrieval, contributing to overall system responsiveness. The 4Rx4 rank configuration indicates a quad-rank design, where each rank is composed of four data bits per DRAM chip. Quad-rank modules can leverage advanced memory interleaving techniques to enhance performance by allowing the memory controller to access different ranks concurrently, thereby increasing bandwidth. As a standard feature for server-grade memory, this Hynix LRDIMM includes ECC (Error-Correcting Code) capabilities. ECC memory is essential for detecting and correcting single-bit errors, which is critical for maintaining data integrity and ensuring system stability in continuous operation environments. The HMT84GL7MMR4A-H9M1AF is a reliable choice for servers requiring substantial memory capacity and robust data protection, ensuring consistent and error-free performance.
