MSI announces BIOS support for Chinese CXMT DDR5 memory support on AMD motherboards up to 8200 MT/s
MSI has released a new test BIOS for AMD motherboards that improves support for DDR5 memory based on Changxin Memory Technologies chips, also known as CXMT.
According to MSI, the update removes a frequency limit that kept many CXMT DDR5 modules at around DDR5-6800 on AMD platforms. The company says its latest tuning now allows DDR5-8000 to DDR5-8200 operation , depending on the memory chips and motherboard layout.
The fastest result applies to dual-DIMM motherboards paired with DDR5 modules using CXMT 24Gbit chips. MSI says this configuration reached DDR5-8200 and passed MemTest with more than 100% coverage. Modules with CXMT 16Gbit chips reached DDR5-8000 under the same validation process.

The test results are as follows:
- Dual-DIMM motherboards:
- With memory using CXMT 16Gbit chips, DDR5-8000 can boot stably and pass a full MemTest burn-in test with 100% coverage.
- With memory using CXMT 24Gbit chips, DDR5-8200 can boot stably and pass a strict MemTest burn-in test with more than 100% coverage, while maintaining stable operation.
- Mainstream four-DIMM motherboards: The frequency limit has also been raised to DDR5-7200.

MSI used retail memory kits from brands such as KingBank and Lexar for the validation. In case you missed it, HardwareUnboxed tested the former recently. Anyway, the tuning is not limited to hand-picked engineering samples, although memory overclocking results can still depend on the CPU memory controller, board model and BIOS version.
The first supported test BIOS files are now available through MSI’s community release channel. MSI says these builds are based on current official BIOS versions and add overclocking-specific changes. More motherboard models are expected to be added later.
Interestingly, I couldn’t find any mention of this CXMT update on global MSI pages.
