Overview

Innodisk's DDR5 12800 MT/s MRDIMM brings Multiplexed Rank DIMM technology — the memory standard designed to break the bandwidth ceiling that has left conventional DDR5 RDIMMs lagging far behind HBM — to Innodisk's industrial and data center product line. MRDIMMs place two ranks behind a multiplexer on the same module so the data bus runs at double the rate, giving roughly twice the effective bandwidth of a standard DDR5 RDIMM at the same capacity per module. At 12,800 MT/s, a single module moves data at a rate that previously required many more channels. That makes MRDIMM attractive for AI inference and HPC servers where the workload is memory-bandwidth-bound rather than compute-bound: LLM token throughput, KV-cache-heavy serving, in-memory analytics, and large-scale scientific simulation. Innodisk's industrial pedigree means the module is qualified for extended-temperature and long-lifecycle deployments alongside the data center MRDIMM parts already in the QS Compute catalogue.
