New RAM chips challenge giants

Chinese memory maker CXMT has begun supplying DDR5 memory to Western markets, seeking to alleviate the ongoing RAM supply crunch. Launched in 2025, CXMT's entry aims to fill the gap left by major manufacturers. However, performance testing indicates that CXMT memory chips exhibit less consistency compared to established brands like SK Hynix, Micron, and Samsung.

Overclocking experiments with CXMT memory showed limited success, with attempts to increase speed beyond the stock 6,000 MT/s proving difficult. The chips demonstrated poor voltage scaling and unresponsive sub-timing adjustments, hindering performance gains. Furthermore, variability between individual RAM sticks was noted, suggesting a more pronounced 'silicon lottery' effect for consumers purchasing CXMT-based memory.

Despite these technical limitations, CXMT's potential for more affordable pricing could allow it to secure a market segment. If the global RAM shortage persists, CXMT may have the opportunity to refine its fabrication processes and improve product consistency and performance over the coming years.
