Chinese memory module manufacturers are accelerating the release of consumer and enterprise storage products powered by domestic DDR5 chips, as breakthroughs by ChangXin Memory Technologies (CXMT), the nation’s leading memory chipmaker, filter through the supply chain.

Powev, one of China’s major memory module vendors, recently said its Sinker-branded DDR5 server memories had entered mass production and delivery. The 64GB DDR5-5600 RDIMM product passed testing by multiple major customers and was ready for bulk supply to enterprise clients, channel partners and branded vendors, the firm said.

The company also introduced the Sinker DDR5 memory modules, said to fully use domestic components, while other Chinese vendors, including Comay, have released DDR5 products based on CXMT dies for industrial and enterprise applications.

In the consumer market, Powev’s Gloway and KingBank DDR5 models based on Chinese made DRAM chips were being sold as early as late 2024, marking one of the first visible signs that domestic DDR5 supply was moving beyond demonstration products and into commercial channels.

The downstream push follows CXMT’s official debut of its DDR5 product portfolio in November last year. The Hefei-based company said its DDR5 chips supported speeds of up to 8,000 Mbps and die densities of 16Gb and 24Gb, targeting servers, workstations and personal computers.

The 24Gb density leaves CXMT roughly one generation behind the most advanced 32Gb DDR5 chips from Samsung Electronics, SK Hynix and Micron Technology, but still represented a significant step forward for China’s domestic DRAM industry.
