MSI has updated its AMD motherboard firmware to support faster DDR5 memory speeds using Changxin Memory Technologies (CXMT) chips. According to reports from VideoCardz, the manufacturer has validated speeds up to 8200 MT/s on two-DIMM motherboards, effectively removing the previous 6800 MT/s ceiling that limited many of these memory kits.
How does CXMT memory perform on AMD platforms?
The performance increase stems from optimized BIOS settings tailored for CXMT modules. MSI reports that its two-DIMM motherboards successfully achieved 8200 MT/s with 24 Gbit CXMT chips, passing MemTest with over 100% coverage. Modules utilizing 16 Gbit CXMT chips reached 8000 MT/s under the same testing protocols.
These figures represent a significant shift from the 6800 MT/s limit previously observed by users. MSI notes that while these results are promising, final performance remains dependent on the specific CPU memory controller, the motherboard model, and the BIOS version installed.
Before these BIOS updates, CXMT-based kits were widely perceived as budget-tier options limited by lower frequency ceilings. This new validation suggests they may soon compete with high-performance modules from established manufacturers like SK hynix or Micron.
What is the impact on four-DIMM motherboard configurations?
Users running four-DIMM setups will also see improved stability and speed. MSI confirmed that its testing on four-DIMM AMD boards has pushed the validated limit to 7200 MT/s. While lower than the two-DIMM results, this represents a notable jump over the previous 6800 MT/s barrier.
The manufacturer utilized off-the-shelf retail kits from brands such as KingBank and Lexar for these tests. By avoiding specialized engineering samples, MSI aims to demonstrate that these speed gains are accessible to typical consumers purchasing standard hardware. Recent reviews from outlets like HardwareUnboxed have also highlighted the growing presence of KingBank memory in the retail market.
How can users access these BIOS updates?
MSI is currently distributing these performance-oriented BIOS files through its community testing channels. These updates are based on the latest AGESA microcode and include specific tweaks for CXMT chipsets. The company plans to roll out support to a broader range of motherboard models in the future.
While these results are currently documented only by MSI, they signal a broader trend of CXMT becoming a more credible player in the high-speed memory market. As more manufacturers integrate these chips into 48 GB kits—as seen with recent offerings from Gloway and KingBank—the market for non-traditional DDR5 silicon is expected to expand.
Pro Tip: Check your memory compatibility
Memory overclocking results vary significantly based on your specific CPU’s integrated memory controller (IMC). Always check your motherboard’s official support page or community forums before flashing test BIOS versions to ensure system stability.
Frequently Asked Questions
- Are these 8200 MT/s speeds officially supported?
MSI is currently providing these through its community BIOS test channels. They are optimized for overclocking and are not yet listed on the official product pages for all motherboards. - Do I need a specific CPU to reach these speeds?
Yes. MSI notes that the final frequency depends heavily on the memory controller quality of your specific processor. - Are these results limited to special test kits?
No. MSI verified these speeds using retail memory kits from brands like KingBank and Lexar to ensure real-world applicability.
