Hardware enthusiast @wxnod posted screenshots of CPU-Z and HWiNFO64 on X on May 22, confirming that a Corsair Vengeance DDR5 memory module—model CMK5X16G3E60C36A2-CN—uses memory chips manufactured by ChangXin Memory Technologies (CXMT). The module features a total capacity of 32GB (configured as two 16GB sticks in dual-channel mode), operates at DDR5-6000 speeds, has a CL36 timing profile, and runs at 1.35V. This marks the first time CXMT’s DDR5 chips have been confirmed to be used in a well-known Western consumer-grade product; previously, Chinese-made memory chips were mostly found in regional or lesser-known brands. The “-CN” suffix in the product number suggests this variant is currently targeted primarily at the Chinese market; Corsair has yet to announce any global release plans. Independent tests on Zen 5 platforms show that these CXMT chips deliver gaming performance comparable to those produced by the three major global manufacturers when operated under similar timing settings.
This revelation highlights growing supply constraints in the consumer DDR5 market: Samsung, SK Hynix, and Micron have redirected nearly all of their production capacity toward HBM and LPDDR5X chips needed for AI servers, resulting in tighter supplies and persistently high prices for standard PC memory. Since CXMT isn’t bound by data center-related contracts, it can allocate its production lines more flexibly to meet demand from the PC sector. Its current DDR5 lineup supports speeds up to 8000MT/s and comes in 16Gb and 24Gb densities, available in common form factors such as UDIMM, SODIMM, and RDIMM. Notably, unlike Yangtze Memory Technologies (YMTC) in the flash memory industry, which has faced U.S. trade restrictions, CXMT remains off the list of restricted entities, granting it relatively easy access to international markets. Analysts predict that as Chinese memory makers ramp up mass production, DDR5 prices could decline by late 2026 or 2027; however, it remains to be seen whether CXMT has reached the scale required to make significant inroads into global supply chains.
