SK hynix HMA451R7AFR8N-UH 4G DDR4 2400 RDIMM
The SK hynix HMA451R7AFR8N-UH is a 4GB DDR4-2400 registered ECC memory module built for enterprise servers, workstations, and storage systems that run continuous 24/7 workloads. It suits resellers and system integrators sourcing replacement or expansion RDIMMs for DDR4-generation platforms, including virtualization hosts and cache or storage tiers where error correction is required. Note that as a registered DDR4 module it is not interchangeable with desktop UDIMM or DDR5 memory — always confirm your platform’s supported DIMM type before ordering.

Good to know
- RDIMMs must not be mixed with desktop UDIMMs or with DDR5 modules; check that your server platform accepts DDR4-2400 registered memory and follow the vendor’s channel population guidelines for single-rank modules.
- Within SK hynix’s DDR4 RDIMM lineup, this 4GB single-rank module is an entry-capacity option well suited to filling spare slots or completing channel balance in hosts where higher-capacity modules are unnecessary.
- Buying tip: when expanding existing servers, match part number and rank configuration where possible to avoid mixed-module configurations, and request batch consistency for volume orders.
