ChangXin Memory Technologies, or CXMT, has just received official validation from MSI for its high-speed DDR5 memory modules. The manufacturer has 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, RAM using these modules was limited to around 6,800 MT/s despite the hardware itself being capable of much more.
The test BIOS comes from MSI China — there's no announcement on global channels for some reason, and it's only available for select motherboards at the moment. MSI tested region-bound retail kits from Lexar and KingBank on boards with both two slots and four slots, but we only have screenshots for the former, courtesy of Videocardz.
One test was conducted using 24GB sticks (2x24) on the MEG X870E Unify model and a Ryzen 7 9700X CPU. This was mostly a standard kit since it came with a 6,000 MT/s EXPO profile. The other config consisted of 16GB sticks (2x16) with an EXPO profile already running at 7,200 MT/s, so it was somewhat cherry-picked silicon, paired with a Ryzen 5 9600X on a MAG B850 MPower motherboard.
The results showed that on dual-DIMM motherboards, 24Gbit (3GB) modules from CXMT were able to clock up to 8,200 MT/s, passing MemTest with 101% coverage. Conversely, 16Gbit (2GB) chips were also stable at 8,000 MT/s on the same test bench with 101% coverage. Moving over to quad-DIMM, the patch notes for the BIOS say they've "also been raised to DDR5-7200," where the limit was stuck at 6,800 MT/s prior.
This is not the first time MSI has optimized Chinese RAM for some of its motherboards. Earlier this year, the company did the same thing for Intel's 800-series models in China. Anyway, these specific BIOSes are meant for the AM5 socket and they're based on existing stable releases — just patched with unlocked memory overclocking features. More motherboards should be supported soon, but for now you can check out the MSI China's community release channel if you want to try one yourself.
