❯ CXMT upgrades DDR5 dies to 32Gb and broadens server memory capacity and bandwidth

Die density and module options advance togetherCXMT has moved its DDR5 dies from 24Gb to 32Gb. Its server RDIMMs span 32GB–128GB at 5,600–8,000Mbps, while MRDIMMs cover 128GB and 192GB with speeds up to 12,800Mbps. The developments were disclosed after Blue Whale Technology spoke with CXMT and summarized by IT Home on November 12.

Denser dies support larger memory configurationsA 32Gb die holds approximately 4GB, one-third more than a 24Gb die, with multiple chips combined into a module. Servers keep active programs and data in memory, so greater density can support larger capacity within a given physical footprint. RDIMMs are registered modules commonly used in servers; MRDIMMs use multiplexing to increase bandwidth for workloads with greater capacity and data-access requirements.

Server demand shapes the product rangeCXMT vice president Luo Xiaodong said memory demand is becoming more differentiated, with servers requiring more high-end memory and high-performance chips. The company reports strong fourth-quarter server-customer demand and expects DRAM supply to remain tight. A broader set of capacities and speeds gives server manufacturers more configuration choices and increases memory suppliers’ importance in system planning and procurement.

▮ SIGNALHigher density and more speed options extend CXMT’s role from supplying chips to shaping server configurations, with platform fit influencing its share of memory procurement.
