MSI tests 128 GB DDR5 CUDIMMs on Z890 boards

MSI has validated new 128 GB DDR5 memory modules, a development that significantly increases the maximum available memory for standard desktop computers. These 4-rank CUDIMMs, double the density of conventional modules, allow a system with two memory slots to support up to 256 GB while operating at 5600 MT/s. This high capacity was previously only attainable with specialized workstation hardware using processors like Intel Xeon or AMD Threadripper.

The company confirmed these modules are stable on its Z890 motherboards for Intel Core Ultra 200 Series CPUs, having overcome challenges related to memory controller stress and signal integrity. This advancement primarily benefits professional workloads, including video production, 3D rendering, engineering applications, and local AI development, where large datasets are common.

Pricing for the ADATA-made modules remains undisclosed, a critical factor for widespread adoption given current elevated DRAM costs. Widespread validation by other motherboard manufacturers could further establish high-density memory within the mainstream computing market.
