CXMT DDR5 memory hits 9,000 MT/s speed milestone on AMD AM5 motherboard

With the current memory crisis leading to DDR5 pricing doubling and tripling over the past year, there's been a lot of focus placed on alternatives that aren't sourced from the Big Three - Micron, SK hynix, and Samsung. As demand still outstrips supply by a huge margin in recent years, we've seen Chinese memory maker CXMT emerge as a new and serious player in the space.

Although CXMT memory in products released in the United States and other Western markets is still relatively rare, the company's evolution in the space has been noteworthy. Recently, it was reported that CXMT's 17nm DDR5 memory yields hit the 90% milestone, suggesting its production quality and facilities are quickly approaching those of its rivals.

On top of this, CXMT memory performance continues to improve. Case in point, an AMD system running COLORFUL's iGame X870E VULCAN W OC motherboard with 48GB (24x2) of CXMT-powered DDR5 memory has achieved an impressive speed of 9,000 MT/s, rivaling kits with chips from the biggest names in the memory space.

Of course, speed is just one metric, as latency and timings matter for real-world performance. On that note, CXMT continues to make strides, with its DDR5 kits hitting 6,000 MT/s with CL30 and even CL28 latency. The latter was captured on an ASUS ROG motherboard. Still, it adds weight to the idea that in 2026, CXMT memory is not only a viable, affordable alternative to the Big Three, but a competitive one.

Question #2

Has CXMT demonstrated lower-latency DDR5 results on other motherboards, and which motherboard hit CL28 at 6,000 MT/s?

Yes. The article reports CXMT DDR5 kits hit 6,000 MT/s with CL30 and even CL28 latency on other motherboards. The CL28 result at 6,000 MT/s was captured on an ASUS ROG motherboard.

Answered

Question #3

How does the article characterize CXMT’s 17nm DDR5 yield milestone and its relevance to product quality?

The article says CXMT's 17nm DDR5 yields hitting 90% suggests its production quality and facilities are quickly approaching those of its rivals. This milestone is presented as evidence that CXMT is becoming a serious, competitive player in the memory market.

Answered

Question #4

What caveats does the article mention about speed versus real-world performance for DDR5 memory?

The article cautions that raw speed is only one metric and does not alone determine real-world performance; latency and timings also matter. It notes CXMT kits have reached 6,000 MT/s with CL30 and even CL28 latency, illustrating that lower latency/tighter timings are important for practical performance.
