Product Description
The Hynix HMT42GR7DFR4C-RDT4 is a 16 Gigabyte Registered DIMM (RDIMM) module based on DDR3 SDRAM technology. It operates at a high frequency of 1866MHz, corresponding to a PC3-14900 data transfer rate, which is beneficial for performance-sensitive server applications. The 'Registered' aspect of the RDIMM means it includes a register chip that buffers the command and address signals between the memory controller and the DRAM chips. This reduces electrical load on the memory controller, allowing for more memory modules to be installed in a system and improving signal integrity, which is crucial for stability in multi-processor or high-memory configurations. This module is organized as 2R x 4, indicating it has two ranks, and each rank has a 4-bit data width. This specific organization is often chosen for its balance of performance and density. The CAS Latency (CL) is 13 clock cycles, which is a standard timing for DDR3-1866 modules. Hynix, a reputable memory manufacturer, designs these modules for the rigorous demands of enterprise environments, ensuring reliability and consistent performance. This 16GB DDR3 RDIMM is suitable for upgrading or populating memory in servers and workstations that support DDR3 RDIMMs and require higher memory capacities and speeds. It is particularly useful for virtualization, large databases, scientific simulations, and other memory-intensive workloads where maximizing RAM is critical for system efficiency and responsiveness. Always confirm system compatibility before installation.
