Many often regard CXMT as an underdog in the memory industry, particularly when compared to the "Big Three." Founded only a decade ago, the ambitious Chinese chipmaker eventually became China's largest domestic memory manufacturer and is now the fourth-largest memory maker globally.
The recent memory shortage has accelerated CXMT’s rise to fame. The chipmaker has been silently gaining ground in the memory market. Its momentum has been especially evident in the DDR5 segment despite the company having only unveiled its first DDR5 ICs in November 2025. Many top Chinese memory brands, including Asgard, Colorful, Gloway, and KingBank, are widely using CXMT ICs, and even Corsair has done so to a certain extent.
Colorful showed off an incredible overclock with its iGame Shadow II DDR5-6000 C34 memory kits, pushing both the 32GB (2x16GB) and 48GB (2x24GB) configurations far beyond their rated speeds. These kits reached DDR5-8812 and DDR5-8817, respectively, on Colorful's iGame X870E Vulcan W OC motherboard. Unfortunately, the screenshots provided by Colorful were too blurry to discern detailed specifications such as memory timings or DRAM voltage. For context, some high-end DDR5-8800 memory kits typically operate at timings around 42-55-55-140 with a voltage of 1.45V.
colorful igame shadow ii 16×2 kit (cxmt 2gb dies) reached 8800mhz mt100% on colorful igame x870e vulcan w oc (2dimm).reaching 8800 for 16×2 is very impressive and much harder to achieve compared to 24×2. based on the pattern we see with hynix dies, for example in z890 qvl, you… https://t.co/XzcS7SaJjV pic.twitter.com/g4aaQ3Q9Sg August 6, 2026
The noteworthy aspect is that Colorful achieved the overclocking feat on 16GB memory modules. Most, if not all, DDR5-8600 and faster memory kits currently on the market come with 24GB memory modules. The reason is that many use SK hynix’s 24Gb (3GB) M-die ICs, produced on the chipmaker's advanced 1a-nm (~14nm) process node with Extreme Ultraviolet (EUV) lithography. These M-die ICs are the go-to choice for memory vendors thanks to their superior density, power efficiency, and ability to scale to higher frequencies.
CXMT's DDR5 RAM isn't as performant or as consistent as SK hynix dies, early testing shows
