Micron Shows Off 512GB DDR5 Rdimm: 12TB per Dual-Socket Server at 9,200 MT/S

9 hours ago
  • Micron announced the world's first 512GB DDR5 RDIMM, running on multiple server platforms and being validated by AMD and Intel for next-generation servers.
  • The module uses vertical die-stacking with through-silicon vias (TSVs) to double capacity per slot without changing server footprint, enabling 12TB in a 24-slot dual-socket system.
  • It is rated for speeds up to 9,200 MT/s and is tied to the 2027 server cycle, with volume production scheduled for the second half of 2027.
  • A single 512GB module cuts operating power by over 60% compared to four 128GB modules (16W vs 44.2W), equating to 31mW per GB versus 86mW.
  • Performance improvements include up to 1.4x higher throughput for memory-bound workloads like Spark SVM-based data analytics, and better concurrency for databases and caching (RocksDB, Redis).
  • AMD, Intel, and JPMorganChase provided validation or customer quotes, highlighting benefits for in-memory workloads, virtualization, and LLM inference.
