ADATA and MSI announce world's first 4-rank DDR5 CUDIMM RAM module with 128 GB capacity for intel's Z890 platform

CUDIMM RAM is seeing increased adoption especially with local AI processing and training becoming more mainstream these days. Thanks to the addition of a client clock driver directly on the RAM module, this type of memory can more stably run at higher speeds and the capacity per module can also be increased to meet local AI model training needs. Previously only limited to 64 GB per module in a dual-rank architecture, CUDIMM RAM modules can now support up to 128 GB per module and ADATA is the first company to present a 4-rank CUDIMM RAM kit with an outstanding 256 GB capacity.

The new High Capacity DDR5 4-rank CUDIMM RAM from ADATA was jointly developed with MSI and is designed specifically for Intel Z890 motherboards. ADATA is the first to implement the 4-rank architecture, essentially doubling capacity over the traditional dual-rank approach and thus offering server-grade capacities for desktop systems.

Even though it features the onboard clock driver, this is not used for higher speeds as the modules are rated for stable operation at 5600 MT/s. Instead, the onboard client clock driver handles the increased electrical load on the memory channel. MSI ensured that its Z890 motherboards can handle up to 256 GB in a dual-DIMM layout.

While the 5600 MT/s speeds quoted by ADATA are not that impressive, MSI seems to hint at some overclocking potential, as the company reports that it has paired a 4-rank CUDIMM module with an “Intel Z890 platform motherboard under development” and the module “completed stable burn-in testing over 10,000 MT/s high frequency (with 1 Rank).” Additionally, the ADATA kit “meets the overclocking optimization features of 1SPC (1 Slot Per Channel) motherboard designs.” It remains to be seen the exact MSI models to support the new 4-rank CUDIMM kits.
