The SK hynix HMCG84AEBRAxxxN 32 GB 1R X 4 4800MHz DDR5 SDRAM RDIMM (Gen 5 Double Data Rate Synchronous Dynamic Random Access Memory Registered Dual In-line Memory Module), a low power, high-speed memory module that uses DDR5 SDRAM components.

Compared to RDIMMs using DDR4 SDRAM components, this device increases effective bandwidth by 70% with a data rate that is 75% higher.

RDIMMs include a Register Clock Driver for command/address signals between the DRAM and system memory controller.

Registered SDRAM DIMMs are intended for use as main memory when installed in systems such as servers, workstations, and networking equipment.
