DDR5 doubles bandwidth per DIMM versus DDR4, adds on-die ECC, and increases bank density. Speeds start at 4800 MT/s and climb to 8000+ MT/s; RDIMM is the server standard.
DDR5 is not backward compatible with DDR4 — slot key and voltage differ. Match the CPU platform's supported speed (e.g., 4800/5600/6400 MT/s) and check the server QVL list.
AI demand drives DDR5 shortage and price fluctuation. Buy from distributors with real stock and original packaging; confirm speed grade, rank and heat spreader type.
