Early testing of CXMT's DDR5 RAM suggests it underperforms compared to SK Hynix dies, exhibiting issues with voltage scaling and manual overclocking. The Chinese-manufactured memory also shows significant variance between batches, indicating a strong silicon lottery effect. Despite these findings, CXMT is scaling production and gaining traction with OEMs and PC hardware companies, with an IPO on the horizon. AI

CXMT's DDR5 RAM isn't as performant or as consistent as SK hynix dies, early testing shows — reveals resistance to voltage scaling and inferior manual overclocking capabilities

Asus is claiming that CXMT-made DDR5 RAM performs worse than SK Hynix-made DDR5 at the same clock speeds, while being harder to manually overclock as well. It also allegedly doesn't scale with voltage or allow the subtimings to be tuned properly.
