Chinese DRAM Maker Enters DDR5 Market with 64GB RDIMMs as Samsung, SK Hynix Lag
▼ Summary
– Chinese DRAM maker SINKER, a subsidiary of Jiahe Jinwei, has launched DDR5 RDIMM memory for servers, offering up to 64 GB capacities and speeds up to 5600 MT/s.
– The company has already shipped its first DDR5 RDIMMs to data centers and plans to increase production to meet domestic demand.
– SINKER’s DDR5 memory comes in UDIMM, SODIMM, and RDIMM variants, with features like power-on protection, shock resistance, and JEDEC compliance.
– Relying on domestic producers helps Chinese firms avoid supply constraints and price hikes from major global suppliers like Samsung, SK Hynix, and Micron.
– Chinese DRAM manufacturers are accelerating production amid rising memory demand from the AI supercycle and new data centers coming online in China.
Chinese memory manufacturers are accelerating their push into the high-performance server market, with a new domestic player now delivering DDR5 RDIMMs at scale. This move comes as global demand for memory surges amid the AI supercycle, while major suppliers like Samsung, SK Hynix, and Micron face tight capacity constraints.
The latest entrant is SINKER, a subsidiary of POWEV under the Jiahe Jinwei umbrella. Originally announced back in 2021, the company has officially launched its DDR5 RDIMM solutions in two distinct product lines: one tailored for the domestic Chinese market and another for global distribution. These modules are available in UDIMM, SODIMM, and RDIMM form factors, with capacities reaching 64 GB and speeds up to 5600 MT/s.
SINKER emphasizes several key features for reliability and durability. The memory includes power-on protection for stable storage, shock and drop resistance for extended longevity, and full compliance with JEDEC standards to ensure plug-and-play compatibility. Targeted applications span mobile terminals like laptops, functional devices such as desktops and all-in-ones, and smart terminals used in education, medical, and government systems. Commercial use cases include large conference centers, advertising displays, and commercial display devices.
The company has already shipped its first batch of DDR5 RDIMMs to data centers, with production ramping up to meet rising domestic demand. This is particularly significant given the global supply constraints that have driven memory prices higher. By leaning on domestic producers, Chinese firms can bypass reliance on Samsung, SK Hynix, and Micron, all of which are heavily invested in AI-driven markets with little spare capacity.
This development mirrors broader trends in China’s semiconductor sector. Earlier reports highlighted how CXMT and YMTC are pursuing massive expansion plans, investing billions to double wafer output. SINKER’s entry into the DDR5 RDIMM space adds another layer of domestic capability, helping to secure supply chains for China’s rapidly expanding data center infrastructure.
