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Indeed, because CXMT produces memory chips using an outdated fabrication technology, its DRAM ICs consume more power than those made using the latest manufacturing processes, have lower performance potential, and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.

A man by the name of Li and his partner by the name of Cheng have been arrested for a string of RAM stick thefts from various hotels in China where gaming PCs are standard room equipment. This was a pretty small-time operation, with a total of ~ 13,200 yuan (about $1,950) raised by selling 16 stolen RAM sticks on the second-hand goods market. However, the source describes the accused thieves as purveyors of "frenzied hotel room-dismantling" (machine translation).

According to the report, Li began his tech treasure crime spree in May, in Shihezi City, Northern Xinjiang. After checking into an eSports hotel, the light-fingered Li couldn’t resist plucking a pair of RAM sticks from the in-room computer. The solo RAM thief’s initial success spurred him to recruit a partner, and in the second two weeks of May, the dynamic RAM duo of Li and Cheng swept through multiple hotels in the aforementioned “frenzied” fashion.

The crime spree might be one of the first of its kind we’ve read about, but it wouldn’t make the thieves filthy rich. The source notes that 16 RAM sticks in total were taken from eSports hotels during the two-week criminal spree. They would sell the slyly stolen sticks of silicon for a total of ~ 13,200 yuan (about $1,950) in profit via a mix of online marketplaces and brick-and-mortar stores.

In the Chinese language report, it is noted that subsequent guests at the eSport hotels complained about systems with black screens, unable to boot. Customer complaints led to investigations by hotel staff, and the police were called out once the DRAM dirty deeds were definitive. Perhaps the duo would have been more successful if they had decided to just halve the RAM in the raided PCs. Guests who followed them would be less likely to loudly complain about RAM-deficient PCs than completely dead ones.

The Chinese media report ends by saying Li and Cheng are both in custody, with further investigations into the pair’s RAM piracy ongoing.

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.

While PC builders, enthusiasts, and gamers are some of the most heavily affected by the AI-driven memory chip shortage, experts have also been warning that this will eventually hit the automotive sector. It seems that their fears have come true, as Nikkei Asia reports that two major automakers are increasing their prices precisely for this reason. General Motors said that it expects new vehicle prices to increase by 0.3% this year, changing its previous projection of vehicle costs to remain the same or even slightly more affordable. On the other side of the world, Chinese automotive giant BYD has also raised the prices of the driver assistance features by 20%, which it sells separately from its models. South Korea’s Hyundai also called on domestic chip manufacturers to strengthen the local supply chain.

GM Chief Financial Officer Paul Jacobson said during the carmaker’s earnings call that GM expects its costs to increase by $1.5 to $2 billion, which is mostly driven by increasing prices of vehicle components, especially DRAM. While most people wouldn’t equate cars with memory chips, the increasing number of features and technologies that buyers expect from new models means that engineers and designers must add more memory compared to models from the past.

Micron said in 2023 that the average vehicle used 90GB of DRAM and NAND, and it’s expecting this combined requirement to jump to 278GB by 2026, with high-end models requiring up to 2TB. A British OEM broke down the memory requirements of vehicles released this year — infotainment systems require between 4GB and 16GB, ADAS and safety systems need 8GB to 32GB, while centralized systems often have a minimum requirement of 16GB and could go as high as 64GB or more. And as AI assistants start becoming available on cars, these systems will require at least 256GB of memory. In fact, Micron predicts that cars with level 4 autonomy will need at least 300GB of RAM, as they’re essentially supercomputers on wheels.

Note that automotive memory isn’t just any high-end chip that you can get from wafer production lines. Instead, these are specialized parts that take months or years to be validated for vehicle use. That’s because they must withstand various environmental factors that cars go through, from weather and constant road vibrations to extreme heat and cold.

All this means that the current memory chip shortage will have an outsize effect on the automotive industry and push prices even higher. This is bad news for the average car buyer, who is already facing record-high prices for new vehicles. And if the chip shortages continue, we might experience delays in vehicle deliveries and a lack of availability worse than what we experienced in 2021 during the height of port closures due to the pandemic.
