ASUS BIOS Update Boosts CXMT DDR5 Memory Speeds Beyond 8000 MT/s

ASUS has released a Beta BIOS update for select AMD 600 and 800 series motherboards that significantly expands memory compatibility for users building with CXMT-based DDR5 modules. This update matters because it removes the previous performance ceiling that restricted these memory kits, allowing enthusiasts to push speeds well beyond the standard 6000 MT/s limit. Buyers using CXMT memory can now access higher bandwidth and improved system stability without needing to switch hardware components. The global release ensures that this performance boost is available to a wide range of users regardless of their region.

Beta firmware expands compatibility for CXMT-based modules on select AMD chipsets

The update targets specific chipsets within the AMD AM5 platform, including the X670 and X870 series motherboards. ASUS has rolled out the new Beta BIOS for multiple boards in these families to address the compatibility gap with CXMT memory chips. The release focuses on enhancing memory performance and system stability for these specific configurations. Users with other chipsets in the 600 and 800 series should check their specific model compatibility, as the rollout is not yet universal across all boards.

Key technical improvements in this BIOS version include enhanced compatibility with CXMT memory chips, which previously struggled to run at higher speeds. The update allows CXMT-based DDR5 memory modules to operate beyond 8000 MT/s, a significant jump from the previous 6000 MT/s cap. In demonstrations, ASUS successfully pushed CXMT-based DDR5 memory modules to 8400 MT/s on a B850 motherboard. The improved performance results from optimized memory training and timing adjustments within the BIOS firmware.

The update currently excludes B650 and B850 chipset models, meaning users with these boards cannot yet benefit from the enhanced memory support. Current availability excludes these specific chipset models, although a future update is anticipated. ASUS stated that the update offers enhanced memory performance, system stability, and compatibility with CXMT memory chips. We looked at the last AMD 600 and 800 Series Motherboards update earlier, where similar balance and stability themes were present.

ASUS has confirmed that the Beta BIOS is a global release, making the updated memory support available to users worldwide. The update can be downloaded from the official ASUS support pages for compatible motherboards. Users are advised to verify their motherboard model and current BIOS version before installing the update. This release represents a notable advancement in optimizing AMD AM5 platforms for high-speed DDR5 memory configurations.
