China’s production of DDR5 RDIMMs for servers has started domestically, aiming to reduce reliance on overseas memory suppliers. Reports say SINKER, a brand under POWEV, has shipped the first batch of DDR5 RDIMMs to data centers, supporting efforts to stabilize local memory supply.
Chinese DRAM makers are expanding production capacity to meet rising demand, particularly as new data centers come online. In 2021, Jiahe Jinwei announced plans to manufacture DDR5 memory, reflecting a broader push to build local supply for next-generation server memory.
SINKER has also announced its latest DDR5 RDIMM solutions, including two variants: one targeted at the domestic Chinese market and another for global distribution. The company’s DDR5 lineup includes UDIMM, SODIMM, and RDIMM modules, with capacities up to 64 GB and speeds up to 5600 MT/s.
According to the company, the modules are designed with power-on protection for reliable storage, shock and drop resistance for durability, and compliance with JEDEC standards to support plug-and-play compatibility.
SINKER states that its DDR5 memory products are intended for applications including notebooks, desktops, all-in-one systems, education and medical devices, government systems, and commercial electronics such as conference centers and digital signage.
SINKER says the first batch of DDR5 RDIMMs for data centers has been shipped and that production is accelerating to continue meeting domestic demand. The move comes as global supply constraints have contributed to significant increases in memory prices.
The company frames domestic production as a way for Chinese businesses to address pricing and availability challenges without depending on major global suppliers such as Samsung, SK hynix, and Micron, which are described as facing high demand from large AI players and having limited spare capacity.
