ADATA and MSI have collaborated to launch the world’s first 4-rank DDR5 CUDIMM memory module, marking a significant advancement in desktop memory technology by achieving a maximum capacity of 128GB per single stick, effectively doubling the previous 64GB limit for single- and dual-rank DDR5 modules. This innovative design employs a 4-rank architecture, which stacks four independent groups of DRAM chips on the module to boost density while incorporating an onboard clock driver unique to the CUDIMM format, ensuring clean signaling and stable performance despite the increased electrical load on the memory bus.
The module has undergone rigorous testing on MSI’s in-development Intel Z890 platform motherboards, demonstrating full compatibility, exceptional stability, and reliable operation at speeds of 5600 MT/s, with burn-in tests confirming endurance up to 10,000 MT/s in lower-rank configurations. It leverages stacked DIE technology to support future scalability and is optimized for 1SPC (1 Slot Per Channel) motherboard designs, enabling high-end users to configure up to 256GB of total memory across just two DIMM slots without needing registered or buffered solutions, which is ideal for compact form-factor PCs. Targeted at demanding applications such as offline AI inference, model fine-tuning, large-scale video and image editing, engineering simulations, multi-VM environments, and high-frequency gaming, this memory provides enhanced expansion flexibility, smoother performance, and greater headroom for localized data processing in professional and creative workflows.
While exact retail launch dates and additional speed specifications beyond the verified 5600 MT/s have not yet been disclosed, the module underscores ADATA and MSI’s commitment to pushing the boundaries of high-capacity, high-performance computing for next-generation desktops.
