MSI B860 Motherboards Get Optimization For “China-Made” CXMT DDR5 Memory Modules

China’s first domestically produced DDR5 memory from ChangXin Memory Technology (CXMT) has received official support on MSI B860 motherboards, potentially reaching speeds of up to 6800 MT/s with four modules installed. This development, initially reported by Sina, marks an important step toward broad compatibility for Chinese-made memory in the global PC hardware market.

Improved Memory Compatibility on B860 Models

As part of their new lineup for Intel Core Ultra Series 2 processors, MSI’s B860-series motherboards—such as the MAG B860 Tomahawk WiFi, MAG B860M Mortar WiFi, and Pro B860M-A WiFi—already have a reputation for improved DDR5 performance. Previously, advanced memory tuning and high frequencies were often associated with more expensive 800-chipset boards. However, with updated BIOS firmware, MSI has extended robust overclocking features to the B860 range, providing:

• Up to 6800 MT/s DDR5 memory speeds under a 4x DIMM configuration.

• Enhanced stability when using locally produced CXMT DDR5 memory modules.

Breakthrough for Domestic DDR5

While these Chinese-manufactured modules do not employ the most advanced process node—partly due to ongoing technology sanctions—reports indicate that CXMT has successfully engineered DDR5 chips capable of acceptable performance levels. The memory dies themselves are notably 40% larger than comparable products from Samsung or Micron. Over time, improvements in local semiconductor manufacturing could reduce chip size and bring down production costs, making domestic solutions more price-competitive.

By providing BIOS updates that enable higher frequencies on DDR5 modules from CXMT, MSI becomes one of the first major international motherboard vendors to explicitly support Chinese DRAM. This validation not only boosts CXMT’s visibility in the market but also paves the way for additional domestic memory makers to pursue similar validation. As local production scales and costs diminish, it is expected that more end-users in China—and possibly beyond—will benefit from broader hardware options.
