256 GB DDR5 RDIMM Memory Based on 32Gb "5th Gen 10nm" Technology Now Fully Certified on Intel's Xeon 6 CPUs

While memory shortages and supply constraints keep gripping the consumer segment, the AI segment remains the top choice for memory manufacturers as demonstrated by SK hynix, who have successfuly become the first memory maker to get their high-density 256 GB DDR5 RDIMM solution certified on the Intel Xeon 6 server CPU platform.

This announcement comes a year after the release of the 32Gb-based 128 GB memory solution, which was validated in January 2025. As per Hynix, the new memory solution offers 16% higher inference speeds and also delivers 18% power savings versus the 256 Gb products based on the previous 16 Gb 1a DRAM. The following is the full presser:

Press Release: SK hynix announced today that it has become the first in the industry to complete the Intel Data Center Certified process to apply 256GB DDR5 RDIMM—a high-capacity server module based on 32Gb fifth-generation 10nm-class (1b) DRAM— to the Intel Xeon 6 platform.

As an Intel Data Center Certified system/platform, 256GB DDR5 RDIMM has completed extensive testing and rigorous validation by Intel’s Advanced Data Center Development Laboratory, and is now the industry’s first server module verified to provide reliable performance, compatibility, and quality when combined with Intel Xeon processors. SK hynix has previously obtained similar validation in January this year for its 16Gb fourth-generation 10nm-class (1a) die-based 256GB product.

By becoming the first in the industry to validate compatibility with Intel’s latest server platform, SK hynix is demonstrating technological leadership in high-capacity DDR5 modules. Based on this, the company will expand cooperation with major global data center operators and continue to lead the next-generation memory market in response to rapidly increasing demand from server customers.

In this new AI-driven infrastructure environment, memory has emerged as a critical determinant of performance. As AI inference models evolve beyond generating simple responses to performing complex logical processes, the volume of data that must be processed in real time is growing exponentially. To manage these massive data sets swiftly and reliably, high-capacity and high-performance memory has become indispensable—driving a sharp increase in market demand.

The company anticipates its latest product to be the ideal solution to meet this growing demand. Servers equipped with the new module deliver up to 16% higher inference performance compared with those using 32Gb die-based 128GB products. In addition, by utilizing 32Gb DRAM chips, the design achieves up to approximately 18% lower power consumption than previous 256GB products based on 16Gb 1a DRAM. With this improved power efficiency and outstanding performance per watt2, the company expects strong interest from data center customers.
