SK hynix has reached a new milestone in enterprise memory by becoming the first semiconductor manufacturer to complete Intel’s Data Center Certified process for a 256GB DDR5 RDIMM built on 32Gb die technology. The certification confirms that the high-capacity server memory module is fully validated for use with Intel’s latest Xeon 6 processor platform, a combination increasingly targeted at AI-driven and data-intensive workloads in modern data centers.
The newly certified module is based on SK hynix’s fifth-generation 10nm-class (1b) DRAM process and represents the industry’s first Intel-validated 256GB DDR5 RDIMM using 32Gb dies. Certification was conducted at Intel’s Advanced Data Center Development Laboratory, where the module underwent extensive testing to verify reliability, compatibility, and performance under real-world server conditions. While SK hynix had previously achieved Intel validation for a 256GB module built on earlier 16Gb die technology earlier this year, the move to 32Gb dies marks a significant step forward in density, efficiency, and scalability.
The certification underscores how memory has become a strategic component in AI-era infrastructure. As inference workloads move beyond simple response generation toward complex reasoning, analytics, and multi-step decision-making, the amount of data processed in real time continues to grow rapidly. This shift places increasing pressure on server memory subsystems, making high-capacity and high-performance DRAM essential for maintaining throughput, minimizing bottlenecks, and controlling power consumption at scale.
According to SK hynix, servers equipped with the newly certified 256GB DDR5 RDIMM can deliver up to 16 percent higher AI inference performance compared with systems using 128GB DDR5 modules based on the same 32Gb die technology. At the same time, the transition from 16Gb to 32Gb DRAM chips enables an estimated 18 percent reduction in power consumption compared with earlier-generation 256GB modules, improving performance per watt—an increasingly critical metric for hyperscalers and enterprise data center operators facing energy constraints and sustainability targets.
By securing Intel’s Data Center Certification ahead of competitors, SK hynix is positioning itself as a technology leader in high-capacity DDR5 memory at a time when demand from cloud service providers, AI platform operators, and large enterprises is accelerating. The company indicated that the certification will support deeper collaboration with global data center customers and system vendors as next-generation server platforms roll out more broadly.
Memory Innovation
Intel also emphasized the importance of close engineering collaboration in bringing the module to market. The certification reflects joint efforts to ensure that emerging memory technologies align with evolving processor architectures and workload requirements, particularly for capacity-hungry AI applications. For customers, the result is a validated building block that reduces deployment risk while enabling higher density configurations within existing server footprints.
The announcement highlights a broader trend in the data center ecosystem: as compute advances driven by AI accelerators and new CPU architectures, memory innovation is increasingly critical to unlocking system-level performance gains. High-capacity DDR5 modules such as SK hynix’s 256GB RDIMM are expected to play a central role in scaling AI inference, in-memory databases, analytics platforms, and virtualization environments without proportionally increasing energy consumption.
Looking ahead, SK hynix said it plans to continue expanding its DDR5 portfolio and responding to demand for memory solutions that balance capacity, performance, and power efficiency. With Intel’s Xeon 6 platform expected to see wider adoption across enterprise and cloud environments, the certified module positions SK hynix to capture early deployment opportunities in next-generation data center builds.
