Product Description
The Hynix HMA81GR7CJR8N-WMT8 is a high-capacity 8GB DDR4 Registered DIMM (RDIMM) memory module designed for enterprise-level computing environments. This module operates at a rapid speed of 2933MHz, ensuring swift data access and processing for memory-intensive applications. The RDIMM form factor includes a register chip that buffers command and address signals, reducing electrical load on the memory controller and allowing for higher memory capacities and improved signal integrity, which is crucial for server stability. Featuring a 1Rx8 configuration, this memory module utilizes single-rank organization with x8 DRAM devices, optimizing performance and efficiency. The CAS Latency (CL) of 21 indicates the number of clock cycles required to access data, providing a balance between speed and timing. As a DDR4 module, it offers significant improvements in bandwidth and power efficiency compared to previous DDR generations, making it an ideal choice for modern servers, workstations, and high-performance computing systems that demand reliable and fast memory solutions. Furthermore, this Hynix memory module is equipped with Error-Correcting Code (ECC) capabilities. ECC memory can detect and correct common types of internal data corruption, significantly enhancing data integrity and system reliability. This feature is indispensable in server environments where data accuracy and uptime are paramount, preventing system crashes and data errors that could arise from memory faults. The HMA81GR7CJR8N-WMT8 is a robust component for upgrading or populating memory in compatible systems.
