China's CXMT Memory Chips Achieve DDR5-8800 Overclock on AMD Platform, Closing Gap with SK Hynix
Chinese memory chipmaker ChangXin Memory Technologies (CXMT) demonstrated a significant overclocking achievement, pushing its DDR5 integrated circuits to speeds of DDR5-8800 on AMD's X870E platform. The feat was showcased by Colorful using its iGame Shadow II memory kits, reaching DDR5-8812 on 32GB (2x16GB) and DDR5-8817 on 48GB (2x24GB) configurations. This performance rivals top-tier ICs from SK hynix, despite CXMT lacking access to advanced EUV lithography due to U.S. export restrictions, relying instead on 16nm DUV technology. The achievement is particularly notable as it was accomplished on 16GB modules, which are typically harder to overclock than 24GB modules. CXMT, founded a decade ago, is now the fourth-largest memory maker globally and recently went public with a 466% stock surge. The company aims to capture 30% of the memory market from the Big Three (SK hynix, Samsung, Micron) by 2030, with its chips already used by brands like Asgard, Colorful, and Corsair.
