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

Homegrown DDR5 memory from China, manufactured by ChangXing Memory Technologies , has been making the rounds lately as more and more vendors start legitimizing it. However, new testing from overclocker Safedisk, shared by Uniko's Hardware, purportedly shows that it actually carries inferior performance compared to similar options from SK Hynix, alongside significant variance in the silicon between different batches. kingbank 2x24 6000c36 1.25 kit (cxmt 3gb dies) on asus c10amanual oc to 8600c44 mt 100%key characteristics of cxmt dies- dont scale with voltage- cant tighten timings- silicon variance appears to be massive between batches- not as strong as hynix when it comes to manual… pic.twitter.com/WNPRiHj233 July 15, 2026 CXMT began producing DDR5 in late 2025 despite lacking any cutting-edge EUV lithography tools. Fast forward to today, and reports of the company matching Micron's memory capacity by this year are now floating around. If true, China would become the second-largest memory maker in the world. At such scale, it's no wonder that many companies in China have already started sourcing CXMT-made RAM to fill the gap in the consumer market. Throughout 2026, we've seen motherboard manufacturers verify CXMT's DDR5 with official BIOS optimizations that allow it to run beyond 8,000 MT/s at this point. OEMs such as Dell and HP are using CXMT RAM in their region-bound systems, and even proper PC hardware companies like Corsair are using CXMT modules . Lexar, Kingbank, Netac, Asgard, Gloaway and more are also producing retail DDR5 kits with CXMT chips. As such, the testing features a Kingbank 48GB (2x24) DDR5-6000 kit running at CL36 and found several weaknesses despite successfully achieving an 8,600 MT/s overclock at CL44. The first revelation is that CXMT modules don't scale with voltage, meaning you can't just increase voltage in hopes of achieving higher clocks. CXMT's DDR5 apparently doesn't respond well to tuning sub-timings either, forcing you to remain stu
