Virtium DDR5 Memory Modules

Virtium DDR5 Memory Modules support Intel’s Alder Lake mobile processors, Sapphire Rapids, AMD’s AM5 platform, and Zen4 Genoa processors. Virtium offers both 4800MT/s and 5600MT/s solutions, the longest product availability, and lower cost of ownership over time. In addition, the high-capacity DDR5 memory modules provide better power efficiencies than those of DDR4.
