ASUS Showcases CXMT DDR5 Memory Reaching 8400 MT/s on AM5 With Kingbank and Lexar Kits

ASUS Showcases AM5 Motherboards Running CXMT DDR5 Memory at Up to 8400 MT/s

ASUS has demonstrated its AM5 motherboards running DDR5 memory based on CXMT DRAM, reaching speeds of up to 8400 MT/s. The showcase highlights the growing performance potential of China-made DDR5 memory modules, especially as more domestic brands begin adopting CXMT chips for mainstream and enthusiast PC builds.

Chinese memory makers have increasingly turned to CXMT DRAM for their latest DDR5 kits. Brands such as Kingbank, Lexar, Gloway, and others are using CXMT-based modules as an alternative to memory chips from the major global suppliers. This shift is becoming more important as the wider DRAM market faces tighter supply and rising demand from AI-related hardware.

A key reason behind the change is that leading memory manufacturers are focusing more heavily on high-margin products such as HBM and LPDDR5X, which are widely used in AI servers, premium mobile devices, and advanced computing platforms. As a result, standard DRAM supply for consumer memory products has become more limited. CXMT is stepping in with increased availability, giving Chinese PC hardware brands a practical option for DDR5 memory production.

ASUS has now joined the list of motherboard makers optimizing support for CXMT-based DDR5 memory on AMD AM5 platforms. The company recently demonstrated several memory kits running beyond 8000 MT/s, proving that these modules can deliver strong performance when paired with the right motherboard and BIOS tuning.

For the demonstration, ASUS used its B850M AYW Gaming OC WIFI7 W motherboard. This board features a 2-DIMM layout, which is generally better suited for high-speed DDR5 memory overclocking than 4-DIMM designs. Motherboards with two memory slots often offer cleaner signal integrity, helping users push RAM speeds higher with improved stability.

The first test used a Lexar DDR5 kit with the model number LD5U16G72C38BV. This memory kit is officially rated at 7200 MT/s with CL38-48-48-86-134 timings at 1.4V. In ASUS’s demonstration, the kit was overclocked to 8000 MT/s while running CL40-52-52-127-144 timings at the same voltage.

The second test featured another Lexar kit, the LD5U16G76C38BV. This model is rated at 7600 MT/s with CL38-48-48-96-144 timings at 1.4V and uses 16 Gb CXMT DRAM ICs. ASUS pushed this kit to 8200 MT/s with CL44-58-58-126-220 timings, showing that CXMT-based DDR5 can scale well beyond its rated specifications.

The final and most impressive demonstration involved a Kingbank 48 GB DDR5 memory kit using 24 Gb CXMT DRAM ICs. This kit is officially rated at 6000 MT/s with CL36-38-38-88-126 timings at 1.25V. ASUS managed to overclock it to 8400 MT/s with CL42-52-52-126-200 timings, making it the fastest result shown in the demo.

These results suggest that CXMT DDR5 memory is becoming increasingly competitive for the DIY PC market, especially for AMD AM5 systems. Speeds above 8000 MT/s were once mostly associated with premium memory ICs from established global suppliers, but CXMT-based modules are now showing they can reach similar territory with the right platform.

The timing is also important. DDR5 memory prices are expected to rise as supply remains tight and demand continues growing across consumer PCs, data centers, and AI hardware. For the Chinese domestic market, locally produced DDR5 memory could become an attractive alternative, particularly if availability remains stronger than imported options.

While high-speed overclocking results can vary depending on the motherboard, CPU memory controller, BIOS version, and individual memory kit quality, ASUS’s demonstration shows clear progress. CXMT-based DDR5 is no longer just a budget-focused option. It is now proving capable of strong overclocking performance on modern AM5 motherboards.

For PC builders, this could mean more choices in the DDR5 market. As brands like Lexar and Kingbank continue releasing CXMT-powered memory kits, users may see broader availability of high-speed DDR5 modules for gaming PCs, workstations, and enthusiast builds.

ASUS’s latest AM5 memory showcase reinforces one message: China-made DDR5 memory is maturing quickly. With speeds reaching up to 8400 MT/s, CXMT DRAM is positioning itself as a serious player in the next stage of the DDR5 market.
