ADATA and MSI announce world’s first DDR5 CUDIMM 4-rank: 128GB per module in Z890

ADATA and MSI have introduced a new DDR5 CUDIMM module that elevates memory capacity to 128 GB per module. The technology presented uses a 4-rank layout, being the first design of its kind for consumer systems.

For your part, ADATA confirmed stable operation at 5600 MT/s on MSI’s upcoming Intel Z890 motherboards. With this, the company allows desktop platforms to access capabilities that previously required workstation-class hardware.

The 4-rank structure places four independent groups of DRAM chips on a single module, doubling the density compared to the common two-rank layout. This design increases the electrical charge in the memory channel. Therefore, ADATA uses its CUDIMM format with an integrated clock driver to keep signaling clean.

MSI’s Z890 platform has undergone thorough burn-in testing. A dual-slot configuration achieves 256GB without needing to switch between registered and buffered memory. However, MSI has not confirmed which motherboard currently in development will support this memory.

The official statement reports that the ADATA 4-RANK DDR5 5600 CUDIMM memory module was Successfully integrated and tested on MSI’s in-development Z890 motherboardsbut as already mentioned, it does not specify which cards.

Stability testing was completed at 5600 MT/s and demonstrated excellent compatibility, performance and stability. However, the company did not release any further information or images.

Officially, ADATA positions the module for systems that process large workloads such as AI inference, model tuning, video editing, and engineering tasks. However, nothing prevents it from being used by gamers.

High memory density also benefits local datasets and multi-VM configurations that currently typically exceed 64 GB or 128 GB. It is also important to note that motherboards with two DIMM slots are mainly aimed at overclocking.

Price not disclosed

We recently reported on the increase in memory prices and commented that, for now, the problem did not seem to be affecting Brazil. In practice, what we said was to take advantage and buy memories before prices rise with new shipments.

Previous shipments currently appear to be running out of stock, and it wouldn’t be surprising if prices increase significantly after Black Friday. This will reinforce the perception of many that this is a “black fraud”.

In particular, what was difficult to find were sets with two modules. And, as ADATA has not yet released the price, the idea is to make a comparison for the estimate. Although, it is easy to estimate that 128 GB modules will be expensive, even more so with the increasing trend.

An Adata XPG Lancer Blade memory (16 GB and 5600 Mt/s) costs R$ 432.99 at Kabum. A kit with 2 modules of 16 GB and 5600 Mhz (Rise Mode) costs R$ 891.99.

At Pichau, an ADATA module (16 GB and 5600 Mhz, not XPG) costs R$ 399.99. A Pichau Hubble (also 16 GB and 5600 Mhz) costs R$ 469.99. Moving on to a 32 GB module from the same brand, the price reaches R$789.99.

Assuming that the price of the new ADATA module follows this pattern, it is easy to expect each module to reach R$3,200.
