Hynix HMAA8GR7AJR4N-WM 64GB DDR4-2933MHz RDIMM 4Rx4 CL21 Memory

Product Description

The Hynix HMAA8GR7AJR4N-WM is a high-capacity 64GB DDR4 Registered DIMM (RDIMM) memory module, engineered for enterprise-level servers and high-performance workstations. Operating at a speed of 2933MHz, it offers a significant boost in data transfer rates compared to lower-speed memory modules, which is crucial for memory-intensive applications such as large databases, virtualization, scientific simulations, and complex data analysis. The RDIMM form factor includes an onboard register that buffers memory commands and addresses, reducing electrical load on the memory controller and allowing for higher memory capacities and improved stability in multi-module configurations. This memory module features a 4Rx4 rank configuration, meaning it has four ranks, with each rank consisting of eight memory chips (x4). This configuration provides higher bandwidth and density, making it suitable for systems that require substantial memory resources. The CAS Latency (CL) of 21 indicates the number of clock cycles it takes for the memory to respond to a column address command. While higher latency can sometimes be a trade-off for higher speeds and capacities, the overall performance is optimized for demanding server workloads where capacity and bandwidth are often prioritized. Furthermore, as an RDIMM, this Hynix module typically supports Error-Correcting Code (ECC) functionality. ECC memory can detect and correct common types of internal data corruption, significantly enhancing data integrity and system reliability. This makes the HMAA8GR7AJR4N-WM an ideal choice for mission-critical applications where data accuracy and uptime are paramount. Its combination of high capacity, speed, and reliability makes it a valuable component for modern server infrastructure.
