China-made CXMT DRAM modules achieved DDR5-8200 speed certification on MSI motherboards, signaling competitive memory supply from Chinese fabs.

ChangXin Memory Technologies (CXMT) has received official validation from MSI for its high-speed DDR5 memory modules. MSI released new beta BIOSes across its AM5 lineup, unlocking stable frequencies up to 8,200 MT/s for 3GB CXMT chips on dual-DIMM motherboards. Previously, memory using these modules was limited to approximately 6,800 MT/s despite the hardware being capable of significantly higher speeds.

The beta BIOS comes from MSI China and is currently available only for select motherboards. MSI tested region-bound retail kits from Lexar and KingBank on boards with both two and four memory slots, with testing results documented for dual-DIMM configurations.

Testing included a 24GB kit (2x24GB) on the MEG X870E Unify motherboard paired with a Ryzen 7 9700X processor, using a standard kit with a 6,000 MT/s EXPO profile. A second configuration featured 16GB sticks (2x16GB) with an existing 7,200 MT/s EXPO profile on a MAG B850 MPower motherboard with a Ryzen 5 9600X processor.

Results demonstrated that 24Gbit (3GB) CXMT modules achieved 8,200 MT/s on dual-DIMM configurations, passing MemTest86 with 101% coverage. The 16Gbit (2GB) variant also proved stable at 8,000 MT/s under the same conditions with identical test coverage. For quad-DIMM systems, the BIOS update raises the memory support ceiling to DDR5-7200, up from the previous 6,800 MT/s limitation.

This represents MSI's continued optimization of Chinese memory manufacturers for consumer platforms. Earlier in 2026, the company applied similar support for Intel's 800-series motherboards in China. These AM5-targeted BIOSes build on existing stable releases and incorporate unlocked memory overclocking features. Additional motherboard support is expected in coming releases.
