Overview
- ADATA and MSI announced a 4-rank DDR5 CUDIMM rated at 128GB per module and demonstrated stable operation at 5600 MT/s on an MSI Intel Z890 board.
- Reporting indicates JEDEC plans to formalize the 4-rank form as 'CQDIMM', though the organization has not publicly released the specification.
- CQDIMM is expected to target native DDR5-7200 speeds to align with Intel’s upcoming 800-series ecosystem.
- A single 128GB module enables up to 256GB on two-slot (1DPC/1SPC) motherboards, expanding capacity for compact or overclocking-optimized designs.
- ASUS and GIGABYTE are expected to add support on new boards, while an isolated claim of >10,000 MT/s in early testing remains unverified.
