Product briefing
Samsung's 64 GB DDR5 RDIMM pairs the company's advanced-node DDR5 DRAM with an integrated PMIC and RCD to deliver dependable mainstream server memory. High Assembly yields from Samsung's vertically integrated DRAM production support consistent large-volume supply, a practical consideration for fleet-scale procurement.
The module supports on-die ECC alongside platform RAS, operates at 1.1 V, and is qualified on current Intel Xeon and AMD EPYC generations. It suits virtualization, web-tier, and database roles where balanced capacity, bandwidth, and power define the memory configuration.
