SK hynix announced that it has become the first company in the world to complete the Intel Data Center Certified process for a 256GB DDR5 Registered Dual In-Line Memory Module (RDIMM) built on 32Gb fifth-generation 10nm-class DRAM. The certification confirms this high capacity memory module meets requirements for performance, compatibility, and reliability when paired with Intel Xeon 6 server processors. RDIMM is a type of memory module used in servers and workstations that includes a register or buffer to improve signal communication with the memory controller.
Intel’s Data Center Certified program involves extensive testing and validation in its Advanced Data Center Development Laboratory. SK hynix’s 256GB DDR5 RDIMM underwent these tests and achieved certification for use with the Intel Xeon 6 platform. The company previously achieved a similar certification earlier this year for a 256GB module based on fourth-generation 10nm-class DRAM. This new certification positions SK hynix’s fifth-generation product as the first in the industry with this level of validation on the latest Intel server platform.
High-capacity memory modules are increasingly important for data center workloads, especially in infrastructure that supports artificial intelligence inference and other data-intensive applications. As data processing requirements expand, memory capacity and speed directly influence system performance. SK hynix highlighted that its 256GB module is designed to address these demands by offering a balance of capacity, performance, and efficiency.
According to SK hynix, servers equipped with the new 256GB module can deliver up to 16 percent higher inference performance compared with systems using 128GB modules built on similar 32Gb DRAM technology. The design also reduces power consumption by about 18 percent compared with previous generation 256GB products that used 16Gb DRAM chips. These figures indicate improvements in energy efficiency and throughput, attributes that matter to data center operators seeking to manage operating costs while handling large workloads.
SK hynix described itself as a “full-stack AI memory creator,” emphasizing its role in developing memory solutions tailored to increasingly complex server and AI workloads. The company said it plans to expand cooperation with major global data center operators and continue supporting next-generation memory markets. Intel representatives commented that the collaboration with SK hynix reflects joint engineering efforts to advance memory technology for data center use.
The DDR5 memory generation, of which this module is a part, represents a step forward compared with its predecessor. DDR5 offers higher bandwidth, better power efficiency, and more robust features that support error correction and stability advantages important in server environments. These characteristics make DDR5 a preferred choice for modern infrastructure where data throughput and reliability are critical.
Deployments of high-capacity RDIMM modules like this one can support workloads across cloud computing, AI training and inference, virtualization, and large-scale database operations. Data centers rely on memory that can sustain high speeds and large data sets, and certification by hardware platform developers like Intel provides assurance for compatibility in real-world environments where reliability matters.
