SK hynix HMT42GR7AFR4C Server RDIMM Memory Module

SK hynix HMT42GR7AFR4C-RD is a 16GB DDR3-1866 ECC Registered RDIMM designed for servers, delivered as a single 16GB stick with a 2Rx4 organization and a 240-pin interface. It runs at PC3-14900R speeds and provides ECC protection with registered buffering, offering improved data integrity and memory reliability in memory-dense systems. Compatible with server platforms that support DDR3 registered memory, including Intel Xeon-based servers, this module is commonly used to upgrade memory in racks and blade servers to support virtualization, databases, and other memory-intensive workloads. As a SK hynix component, HMT42GR7AFR4C-RD is positioned for data centers and enterprise environments that require scalable, error-correcting memory without altering standard RDIMM-compatible system architectures.
