Corsair DDR5 RAM with CXMT DRAM chips reveal shift in the memory supply chain

This move comes as AI memory demand is changing the production priorities of the industry's key suppliers. Samsung, SK Hynix and Micron have shifted a significant portion of their manufacturing capacity to AI-specific solutions such as HBM and LPDDR5X. This reallocation has limited the availability of standard DRAM for PC component manufacturers and OEMs.

Recent sightings of Corsair Gaming Vengeance modules show the use of CXMT chips. Specifically, a 16 GB module with a clock rate of 6,000 MT/s and CL36 timings has been identified under the ID CMK5X16G3E60C36A2-CN. These modules support both Intel XMP and AMD EXPO and operate in a voltage range from 1.1 V to 1.35 V. In terms of performance, these specifications are very similar to those of Samsung and SK Hynix A-Die memories.

CXMT has expanded its technical capabilities to compete with established suppliers and now produces DDR5 DRAM with speeds of up to 8,000 MT/s and chip densities of 16 Gb and 24 Gb. At the same time, other Chinese companies such as Jiahe Jinwei are ramping up production of RDIMMs for professional workstations and data centers.

The transition to Chinese memory is being driven by both availability and cost. As companies like CXMT and YMTC aggressively expand to double their wafer production, they are able to meet domestic demand while offering competitive pricing to international suppliers. This expansion allows PC manufacturers to maintain their product pipelines despite the production bottlenecks caused by the AI sector.
