Micron has crammed 512 GB of DDR5 memory into a single stick, pushing next-gen Intel and AMD servers to a staggering 12 TB of total memory in a single 24-slot dual-socket server.

The module, built using advanced vertical interconnect packaging, stacks DRAM dies and connects them with through-silicon vias to maximize density without sacrificing performance. This allows a single 24-slot dual-socket server to handle up to 12 TB of DDR5 memory, which is a staggering amount. Micron says the design improves power efficiency by over 60% compared to using four 128 GB RDIMMs.

"Micron continues to set the pace for memory technology, delivering a new class of ultra-dense, high-performance server memory that helps customers keep larger datasets closer to the compute engines that need them. A 512GB RDIMM enables multi-terabyte servers, supporting larger AI and database workloads, greater virtualization density and improved power efficiency, all within existing server footprints," said Raj Narasimhan, senior vice president and general manager of the Cloud Memory Business Unit at Micron
AMD and Intel are actively validating the module, which is slated to deliver speeds of up to 9200 MT/s. Micron says the module helps keep larger datasets closer to the compute engines, reducing reliance on slower storage tiers and improving performance in AI, analytics, and database workloads.
"AMD solutions continue to advance data center performance, scalability and efficiency as AI and data-intensive workloads reshape infrastructure requirements. Our close engineering collaboration with Micron brings compute and memory innovation together to help customers realize the full value of AMD-powered platforms. Together, we're enabling balanced, high-performance infrastructure for the growing scale and complexity of modern workloads," said Amit Goel, corporate vice president, Compute and Enterprise AI Platform Solutions Engineering, AMD
