Hynix HMA84GR7AFR4N-VKB3 32GB DDR4-2666MHz RDIMM 2Rx4 CL19 Memory

Product Description

The Hynix HMA84GR7AFR4N-VKB3 is a 32GB DDR4 Registered DIMM (RDIMM) memory module, designed for high-performance server and workstation applications. It operates at a speed of 2666MHz, corresponding to the PC4-21300 standard, offering robust bandwidth for demanding workloads. The module has a CAS Latency (CL) of 19, a common specification for DDR4 memory at this frequency, ensuring efficient data retrieval. This module features a 2Rx4 configuration, indicating it is dual-ranked with memory chips organized in an x4 configuration. Dual-rank modules can offer performance advantages in certain server architectures by providing more memory banks for the controller to access concurrently. The x4 organization of the DRAM chips is also a factor in performance and density. As a Registered DIMM (RDIMM), it includes an onboard register that buffers command and address signals. This buffering reduces the electrical load on the memory controller, allowing for higher memory capacities and improved signal integrity, which is crucial for systems populated with many memory modules. Furthermore, this RDIMM supports Error-Correcting Code (ECC) functionality. ECC memory is vital for enterprise environments as it can detect and correct single-bit errors, significantly enhancing system stability and data integrity, thereby preventing costly downtime and data corruption. The module operates at the standard DDR4 voltage of 1.2V, ensuring compatibility with a wide range of server platforms that support DDR4 memory. Its combination of capacity, speed, and ECC support makes it an ideal choice for memory-intensive tasks such as virtualization, large databases, and complex scientific computing.
