Chinese Firms Launch DDR5 Memory Modules Using CXMT Chips, One Generation Behind Global Leaders
Powev has begun mass production and delivery of its Sinker-branded 64GB DDR5-5600 RDIMM server memories, which passed testing by multiple major customers. The move follows CXMT's official debut of its DDR5 portfolio in November 2025. Other vendors including Comay have also released products based on the domestic chips.

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 filter through the supply chain, South China Morning Post reported.
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 is ready for bulk supply to enterprise clients, channel partners and branded vendors.
The company also introduced the Sinker DDR5 memory modules that fully use domestic components. 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. These releases marked 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 2025. 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. Founded in 2016, CXMT is regarded as China’s only domestic DRAM maker to have achieved mass production.
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. Comay has released DDR5 products based on CXMT dies for industrial and enterprise applications.
