ADATA and MSI showcase “world’s first” 4-RANK 128GB DDR5 CUDIMM memory modules

ADATA launches the world’s first 4-rank 128GB DDR5 memory modules at CES 2026

At CES 2026, ADATA and MSI showcased the world’s first 4-rank 128GB DDR5 memory modules. These new DDR5 CUDIMM memory modules use four memory ranks, twice the number traditionally used in DRAM modules. This change allowed ADATA to double the number of DRAM chips on its modules, doubling its total memory capacity.

MSI co-developed this memory technology and tested it on the Intel Z890 motherboard platform. With two of these modules, users can have access to 256GB of memory. That’s game-changing for motherboards with just two DDR5 memory slots.

World’s First 4-RANK Design Doubles Capacity and Advances Stability

The ADATA High Capacity DDR5 4-Rank CUDIMM Memory Module adopts the industry’s first 4-RANK architecture, doubling capacity compared with traditional 2-RANK modules. Engineered for large-scale applications and data-intensive workloads, it also retains the hallmark high-speed, stable performance that defines ADATA’s CUDIMM technology. Even under demanding conditions, it delivers excellent data-transfer efficiency and low latency, reinforcing ADATA’s leadership in advanced DRAM innovation.

MSI overclocked these modules to 10,000 MT/s

Using an “in-development motherboard”, MSI has managed to overclock ADATA’s DDR5-5600 CUDIMM modules to 10,000 MT/s. That’s a 63% overclock. This means that ADATA’s new memory type can deliver high speeds and ultra-high capacities. That’s great news for high-end users, as this pairs fast memory access and high-capacity DRAM modules.

MSI, in collaboration with ADATA Technology, has jointly launched the world’s first desktop CUDIMM memory module supporting 4 Rank with a maximum capacity of 128GB for single-stick. Paired with MSI’s Intel Z890 platform motherboard under development, this memory module has completed stable burn-in testing over 10,000 MT/s high frequency(with 1 Rank), demonstrating exceptional performance and stability. Meanwhile, it is greatly enhancing expansion flexibility for 2 DIMM motherboard configurations has also been, users can achieve an enormous total capacity of 256GB.
ADATA High Capacity DDR5 4 Rank CUDIMM Memory Module not only meets the overclocking optimization features of 1SPC (1 Slot Per Channel) motherboard designs but also fulfills the dual demands of high capacity and high frequency performance required by high-end gamers and professionals. In addition, this technology reserves future expansion potential by supporting stacked DIE technology, showcasing both foresight and sustainable scalability.

With workstation users demanding higher memory densities and speeds, ADATA’s 4-rank DDR5 CUDIMM modules meet this market need. However, rising DRAM prices will make these modules insanely expensive.
