One of the common misconceptions in today's memory market is that once memory modules based on chips from CXMT enter the consumer market, there will be cheaper alternatives to memory sticks running DRAM from the Big Three. While availability of CXMT-powered modules certainly impacts average selling prices, these products are not cheaper than those based on ICs from Micron, Samsung, and SK hynix even in China, as noticed by @harukaze5719.

A 64GB DDR5-5600 RDIMM based on memory from Samsung or SK hynix costs 18,595 CNY ($2,745) at JD.com, whereas a module featuring the same capacity and specification, but using DRAMs from CXMT is priced at 18,999 CNY ($2,805), according to observations by @harukaze5719. It is noteworthy that a Samsung 64GB DDR5-5600 RDIMM made by Samsung and sold by Samsung costs $2,425 at Amazon.com in the U.S.

While the $60 difference seems significant, it is really just 2.2%, which can be considered negligible at these sky-high prices. Nonetheless, many expect CXMT-based memory modules to be cheaper than those carrying chips from Micron, Samsung, or SK hynix, so observing that they are even a bit more expensive than offerings with ICs from renowned manufacturers may be a bit surprising.

Indeed, because CXMT produces memory chips using an outdated fabrication technology, its DRAM ICs consume more power than those made using the latest manufacturing processes, have lower performance potential, and mediocre overclockability. Furthermore, the Chinese government heavily subsidizes both ChangXin Memory Technologies and Yangtze Memory Technologies (YMTC), which enables both to sell their memory at lower prices although their actual costs may be higher compared to those of the Big Three.

As a result, it is reasonable to expect CXMT to charge less for its chips compared to chips from renowned producers. Truth to be told, we do not know CXMT's quotes, they may be as high as those from other manufacturers and the only reason why module producers buy them is that they are the only chips available. Furthermore, companies tend to price products based on what the market will bear, not strictly on production cost or their characteristics. In fact, as everyone is capacity constrained these days, there is little incentive for CXMT to price its DRAMs significantly below those from renowned makers. However, while CXMT may indeed charge less for chips (e.g., because the Chinese government issues an appropriate directive), this lowers costs for module makers, but has a limited effect on retail prices of actual DIMMs or RDIMMs.

Whether potential savings reach end customers depends on market competition, supply-demand conditions, and the pricing strategies of module makers, distributors, and retailers. Furthermore, when prominent companies like Apple, Dell, or Corsair use a memory chip SKU, this one must pass rigorous validation processes and is usually tested in-house, or by contract manufacturers, which adds to costs and somewhat erases the price difference between suppliers.

As a result, CXMT memory chips may make the lives of hardware makers easier, but are not expected to impact the retail prices you pay.

You're probably already well aware of the three largest memory vendors: South Korea's SK hynix and Samsung, and the United States' Micron. There's a fourth player up and coming in the market, though, and that's China's ChangXin Memory Technologies, more commonly known as CXMT. CXMT is pumping out RAM as fast as it can to soften the effects of the RAMpocalypse on domestic (to China) consumers, and it's also expanding capacity quickly. Given these factors and the size of the Chinese market, it should come as no surprise that motherboard vendors, including Gigabyte, are advertising fresh support for the chip.

MSI appears to have been the first major motherboard vendor to publicly promote BIOS optimizations specifically for CXMT DDR5 memory, initially through China-market BIOS releases and later with global announcements. What Gigabyte is saying is a little different: not only is CXMT RAM supported on Gigabyte motherboards for both AMD's Socket AM5 and Intel's LGA 1851, but it's supported at impressive speeds of up to 8200 MT/s on select boards.

As proof, Gigabyte offers up a CPU-Z screenshot showing a pair of 16GB Lexar modules equipped with CXMT chips achieving a speed of 8200 MT/s with a CAS latency of just 40 cycles on one of its B850M FORCE motherboards. We have to remark that Gigabyte doesn't show the voltage required to hit these speeds, likely for good reason, but the firm did it without disabling the chip's integrated graphics. That doesn't prevent the chips from posting an excellent AIDA64 latency of just 65.4 nanoseconds on the monolithic Ryzen 5 8600G used for the test. For context, typical EXPO kits usually run around 80ns, JEDEC timings are more like 100ns, and LPDDR-based systems rarely come below 110-120ns.

As Gigabyte says, "CXSH (CXMT) chip-based memory offers a welcome additional source of supply for consumers." (CXSH is the JEDEC manufacturer ID code for CXMT) Gigabyte specifically notes that it is modules with 16-gigabit and 24-gigabit ICs that are supported; that means 16GB and 24GB single-rank modules, or 32GB and 48GB dual-rank modules.

While CXMT memory is certainly a welcome additional source of supply, it's also not really clear how much of that memory is actually making its way outside of China, particularly to the US and Europe. CXMT isn't on the US Commerce Department's "Entity List" yet, so the firm's parts aren't actually banned, but the company is once again considered a Chinese military company by the Department of Defense after being briefly removed from the 1260H list in February. Lawmakers here in the states, likely laden with donations from the big three memory firms, want to see CXMT banned, while US tech companies like Corsair, HP, and Dell are already integrating ChangXin RAM into their products, and Apple wants in, too.

The reality is that, as a DIY builder, you are fairly unlikely to know or care if your memory is manufactured by CXMT. You don't usually buy RAM directly from SK hynix, Samsung, or Micron (certainly not since Micron unceremoniously executed Crucial); you buy your RAM from Silicon Power, G.SKILL, Patriot, Corsair, or one of the many other vendors who assemble DIMMs. If the RAM runs at its rated specifications, there's not a lot of reason for the individual consumer to care where it came from. It's nice to hear that the new chips are officially supported by familiar mainboards, though.

As Apple and other American companies seek to use memory chips from China-based CXMT and YMTC amid massive supply constraints, U.S. lawmakers want to ban exports of Chinese memory chips to the U.S., citing concerns of weakening domestic and allied suppliers and indirectly supporting the development of 3D NAND and DRAM by Chinese companies, reports the Financial Times.

John Moolenaar, Republican chair of the U.S. House China Committee, and Democratic Congressman George Whitesides asked Commerce Secretary Howard Lutnick to prevent U.S. companies from purchasing semiconductors from businesses included either on the Pentagon's Chinese Military Companies blacklist or the Commerce Department's Entity List. They also called on the administration to add CXMT to the Entity List and impose additional restrictions on YMTC.

"Dependence on Chinese memory manufacturers creates an unacceptable risk for U.S. national security, economic security, and supply chain security," the letter by Moolenaar and Whitesides reads.

Apple has been seeking approval from the Trump administration to source memory from CXMT amid a severe global DRAM supply crisis caused by the rapid expansion of AI infrastructure. Corsair, Patriot Memory, and some other suppliers of branded memory modules and SSDs have been using DRAM from CXMT and 3D NAND from Yangtze Memory for some time now.

"We are alarmed that Apple and other U.S. tech companies seek to purchase memory from Chinese semiconductor manufacturers, including those with ties to the Chinese military," the U.S. lawmakers wrote.

DRAM maker CXMT is already on the Pentagon's Chinese Military Companies list, whereas 3D NAND producer YMTC is already in the DoC's Entity List. Their presence in the lists does not outright prevent American companies like Apple from buying their products, but at a significant political risk.

Technically, American companies could buy chips from CXMT and YMTC to use inside products bound for China or other countries and continue to use memory from traditional suppliers in products aimed at the U.S. market. To prevent this, Moolenaar and Whitesides also urge the American government to coordinate with Japan, South Korea, and the EU to prevent CXMT and YMTC from taking advantage of the current supply shortage to establish themselves in allied supply chains, which they believe could ultimately leave the West strategically dependent on Chinese memory.

Moolenaar and Whitesides argue that purchases from Chinese memory manufacturers could indirectly support technologies applicable to China's military.

"Leading Chinese memory manufacturers are all closely intertwined with the Chinese military; thus, every memory purchase by a U.S. company will directly subsidize the People’s Liberation Army's development of this critical dual-use technology," the letter stresses.

The lawmakers argue that CXMT and YMTC could repeat China’s playbook in solar, steel, telecom, and EV markets: use state subsidies to undercut foreign rivals, weaken their investments, and ultimately exploit the resulting dependence for strategic leverage. That said, using Chinese memory now could permanently weaken Western production capacity and leave the West strategically dependent on China for a critical component of AI infrastructure, Moolenaar and Whitesides believe.

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.

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 stuck with baseline CAS latency (or higher, like in this case).

Different batches of CXMT-equipped memory perform differently, too, so silicon lottery plays a much bigger role than it would with other vendors. Speaking of which, SK Hynix-made DDR5 modules allegedly performed better at identical clock speeds, while CXMT's modules were less susceptible to overclocking in general. We didn't get any comparative benchmarks for any metric, so take these claims with a grain of salt.

Overall, if the testing is to be believed, it serves as counterprogramming against the popular narrative forming around China as the savior of consumer interests. CXMT's strength lies in the fact that it doesn't have to cater to opulent AI clients as much as the Big Three, which reduces opportunity cost, allowing CXMT to produce more DDR5 memory. That doesn't mean it would be cheaper, though, or at least no evidence has suggested that so far.

CXMT has remained limited to the Chinese region for now, and breaking through to the Western market would mean impressing a lot of skeptics. Not only would pricing play a big factor, but the reliability of a new DRAM manufacturer would raise serious concerns. Stories like these certainly don't help, but with CXMT's IPO on the way, it's only a matter of time before it becomes a serious mainstream contender.

ChangXin Memory Technologies (CXMT), China's largest DRAM maker, is on track to match Micron's production capacity in 2026, if Citrini Research's forecasting models are correct. If this happens, China will become the world's second-largest DRAM production base in the coming years.

The bottom-up model estimates that CXMT will finish 2026 with approximately 350,000 wafer starts per month (WSPM) of DRAM capacity, which is just 25,000 WPM less than Micron. According to the analysis, the federal government is pushing CXMT to share its DRAM technology with JHICC, Swaysure, and YMTC's subsidiary XMC to ease domestic shortages. All three companies have either built DRAM capacity already, or will do so in the short-term future, the report claims.

Swaysure has completed construction of a 140,000-WSPM fab in Shenzhen, while JHICC's Jinjiang complex contains enough cleanroom space for 120,000 WSPM, and the initial 60,000-WSPM phase is expected to receive equipment by the end of 2026. YMTC is also projected to operate about 50,000 WSPM of DRAM production at Wuhan Fab 3. If all these facilities initiate operations in the coming years, then China will have a total DRAM capacity of 600,000 WSPM (not counting Samsung's and SK hynix's fabs in China), which is dramatically lower compared to South Korea, but ahead of Japan, Taiwan, and the U.S. combined.

But China is not going to stop developing its DRAM industry, and by 2030, its total capacity will increase to around 1.41 million WSPM, according to Citrini. CXMT alone is projected to build new production capacities in Beijing, Hefei, and Shanghai, to expand its production capability to 950,000 WSPM in 2030, assuming everything goes as planned.

The supply model assumes that about 400,000 WSPM of CXMT output will remain on D1a, another 400,000 WSPM will migrate to D1b, and roughly 150,000 WPM will produce D1c devices.

Enough fab tools?

Citrini admits that producing China's outlook is considerably more difficult than predicting the development of established DRAM makers. On the one hand, there is rapidly expanding fabrication infrastructure in China, abundant state-backed financing, and government-directed technology transfers. On the other hand, among the key near-term limitations remains lithography equipment availability, particularly if the proposed MATCH Act restricts sales of advanced immersion DUV tools to select Chinese companies.

However, the author expects SMEE's domestic immersion DUV scanners to enter volume production around late 2026 or early 2027 following beta testing, as well as SiCarrier/Yuliangsheng introduce its own production-ready DUV platform in 2028. Perhaps a bit optimistically, the analysts predict that availability of lithography tools is not expected to constrain Chinese production beyond 2028, at least for mature logic and DRAM nodes. Yet, for obvious reasons, if the MATCH Act works as planned and disrupts supply of advanced immersion DUV tools to DRAM makers, production capacity expansions will not occur in the next couple of years, the report suggests.

Still, both SMEE and SiCarrier will need time to ramp up production of their lithography systems, whereas DRAM makers must learn how to use them efficiently, so we would not be as optimistic as the authors and would not expect Chinese tools to produce meaningful DRAM volumes before the early 2030s. Still, the key takeaway here is that China is on track to become a major DRAM maker rather sooner than later.

Unprecedented demand

Citrini Research projects total DRAM demand to reach 157.5 exabytes (EB) per year by 2030, including 75 EB of commodity DRAM for agentic AI CPUs, 25 EB of commodity DRAM for conventional cloud servers, 20 EB of commodity DRAM for client devices, and 37.5 EB of HBM4E as well as HBM5 for AI accelerators (15 EB and 22.5 EB, respectively).

Meanwhile, Citrini expects the whole industry to only produce around 37.5 EB of HBM4E/HBM4 memory (mostly by Micron, Samsung, and SK hynix) as well as 91.3 EB of commodity DRAM (including output in China) in 2030, leaving a deficit of 28.7 EB, or roughly 25%.

That said, the rapid expansion of DRAM production in China could be the industry's best hope to maintain relatively low prices of memory, something that will be particularly beneficial for the market of consumer devices that are sensitive to memory prices, analysts from Citrini believe. Yet, the author argues that most of this new capacity would satisfy China's own demand rather than eliminate the global shortage. Furthermore, even if companies like CXMT can expand their fabs faster, that additional capacity will mostly be consumed by domestic needs, according to Citrini.

It should be noted that to make more memory, DRAM makers need more fab tools, primarily 193nm immersion scanners. Yet, companies like ASML, Canon, and Nikon cannot increase output of immersion DUV systems quickly as these are extremely complex machines containing tens of thousands of parts. While Chinese memory companies certainly pin their hopes on local producers like SMEE and SiCarrier, neither has delivered a single commercial immersion system, and after they do, it will take them years to ramp up production of such tools.
