Mainstream DDR5 memory has finally reached 128 GB per module capacity with the debut of ADATA 4-RANK DDR5 CUDIMM.

ADATA and MSI Collaborate to Launch 4-Rank DDR5 Memory Modules, Bringing Up to 256 GB on 2-DIMM Platforms

The mainstream desktop platform has finally received its first 4-Rank DDR5 memory, which increases the maximum capacity per module from 64 GB to 128 GB. Through a 4-Rank design, the memory capacity has been doubled by ADATA, which collaborated with MSI to prove that its 4-Rank DDR5 CUDIMM modules can work stably on the Z890 platform.

The current DDR5 memory segment only as single and dual-rank DDR5 memories, which max out at 64 GB memory capacity. By doubling the capacity, the latest desktop platforms can now help in configuring up to 256 GB DDR5 even with dual-DIMM motherboards. As far as 4-Rank DDR5 memory is concerned, it is usually seen on servers, and mainstream platforms have to rely on 64 GB x2/x4 configurations.

With a 4-Rank design, there are essentially four groups on each module, which deliver higher capacity by stacking more chips. This does result in more load on the memory bus, which can affect performance, but higher memory capacity is beneficial in a lot of memory-intensive apps, where the benefits of more capacity outweigh the benefits of higher frequency.

ADATA tested its 4-Rank DDR5 5600 MT/s CUDIMM memory module on MSI's "in-development" Z890 motherboards, confirming full compatibility, stability, and performance. With such high-capacity modules, now it will be possible to build compact form-factor PCs utilizing dual-DIMM motherboards without worrying about hitting the capacity ceiling. This will be great for heavy workloads, especially AI operations, as well as content creation apps that rely on higher system RAM.

It enables offline AI inference, model fine-tuning, large-scale video and image editing, and localized data analysis with remarkable efficiency. Even in offline environments, users can execute AI workloads seamlessly, achieving highly efficient on-device computing with smoother performance and greater memory headroom, empowering next-generation creativity and productivity.
