SK hynix HMT42GR7BFR4C-RD 16G DDR3 1866 RDIMM
The SK hynix HMT42GR7BFR4C-RD is a 16GB DDR3-1866 registered DIMM (RDIMM) built for enterprise servers, workstations, and storage systems still running DDR3-generation platforms. It suits buyers maintaining or expanding virtualization hosts, cache tiers, and legacy infrastructure where ECC-registered memory is required. Note that DDR3 RDIMMs cannot be mixed with DDR4 or DDR5 modules, so confirm your platform generation before ordering.

Good to know
- Compatibility: as an ECC registered DIMM, this module is intended for server/workstation boards with RDIMM support — it will not work in standard desktop boards, and DDR3 RDIMMs cannot be mixed with DDR4/DDR5 memory in any configuration.
- Within its family: at DDR3-1866 (PC3-14900), this is a high-end DDR3 speed grade, and the dual-rank 2Rx4 configuration helps capacity density per channel for memory-hungry workloads such as virtualization hosts and cache tiers.
- Buying tip: for best performance, populate memory channels symmetrically with identical modules (matching capacity, rank, and speed grade) per your server vendor’s population guidelines, and verify the exact part number against your platform’s qualified memory list.
For tray and reel pricing, current stock by part number and date code, and volume discounts on bulk orders, request a bulk quotation.
