MSI’s latest beta BIOS releases for AM5 motherboards have officially validated faster-than-retail speeds for memory modules based on ChangXin Memory Technologies’ CXMT DDR5 chips. The update, currently available through MSI China’s community channels, enables stable operation up to 8,200 MT/s on dual-DIMM configurations—far exceeding the 6,800 MT/s ceiling that retail kits previously faced.
Breaking the retail ceiling with optimized BIOS
Until now, CXMT-based DDR5 memory kits sold in retail were capped at around 6,800 MT/s despite the underlying silicon being capable of much higher frequencies. MSI’s new BIOS patches unlock this headroom by removing firmware-imposed speed limits, allowing enthusiasts to push CXMT modules to their silicon’s true potential. The change is not universal: the updated firmware is region-locked to MSI’s Chinese product lineup and currently supports only select AM5 motherboards.
Validation across test configurations
MSI tested two common retail configurations to confirm stability at the new speeds. The first used 24GB kits (2x24GB) running a standard EXPO profile at 6,000 MT/s on an MEG X870E Unify board paired with a Ryzen 7 9700X. After applying the beta BIOS, the same kit passed MemTest with 101% coverage at 8,200 MT/s. The second test involved 16GB kits (2x16GB) with an EXPO profile already running at 7,200 MT/s on a MAG B850 MPower board with a Ryzen 5 9600X—these also achieved 8,000 MT/s with full stability.
Quad-DIMM support raised to 7,200 MT/s
Beyond dual-DIMM setups, MSI’s BIOS update also lifts the speed ceiling for quad-DIMM configurations from 6,800 MT/s to 7,200 MT/s. This change targets motherboards with four memory slots, where thermal and signal integrity constraints previously limited performance. The update is built on existing stable BIOS versions and simply enables higher memory overclocking profiles targeting CXMT-based modules.
Regional availability and future rollout
The beta BIOS images are distributed exclusively through MSI China’s community release channel and are not listed on global support pages. The company has not announced plans to extend the update to international product lines, though similar past optimizations for Intel-based boards in China suggest wider adoption may follow. Users interested in testing the new speeds should check MSI China’s community forum for compatible motherboard models and download instructions.
This development underscores growing ecosystem support for domestic memory solutions in China, following earlier optimizations for Intel’s 800-series motherboards earlier this year. As chipmakers and board vendors continue to refine compatibility, end users gain access to higher memory speeds without hardware upgrades—only firmware updates.
