Colorful pushes CXMT DDR5 memory to 8600 MT/s as Chinese DRAM gains ground

Colorful has shown a new speed record for DDR5 memory using CXMT chips, pushing its iGame Shadow II memory kit to 8600 MT/s on an AMD AM5 platform. The result is notable because CXMT based DDR5 modules were previously seen as much more limited, with many kits staying around 6000 MT/s before recent BIOS improvements began unlocking higher speeds.

The demonstration used Colorful’s iGame X870E Vulcan motherboard with AMD’s Ryzen 9 9950X3D processor. The memory kit used CXMT 2GB DDR5 dies in a 2 x 16GB configuration. A CPU Z screenshot showed the memory running at 4299.9 MHz, which works out to 8600 MT/s effective speed.

This now appears to be the highest reported speed for a CXMT based DDR5 kit, moving ahead of recent demonstrations from MSI and ASUS. MSI had recently pushed CXMT DDR5 to 8200 MT/s on a B850 motherboard through a BIOS update. ASUS later reached 8400 MT/s on its AMD 800 series boards with updated BIOS support. Colorful has now gone one step further.

The 8600 MT/s result shows how quickly CXMT memory support is improving

The speed alone is important, but stability also matters. According to the report, Colorful’s 8600 MT/s configuration passed RunMemTestPro, which suggests the setup was not only a screenshot result. The memory was also running at CL46, which is a reasonable timing for DDR5 at this speed, especially for CXMT based chips.

This progress matters for more than overclocking records. China’s CXMT has been working to grow its position in the memory market, and DDR5 maturity is a key part of that effort. If CXMT based kits can continue moving beyond 8000 MT/s with stable operation, motherboard vendors and memory brands may have more room to build faster kits using Chinese DRAM.

The recent results also show the importance of BIOS tuning. CXMT based DDR5 kits did not suddenly become stronger in isolation. Motherboard makers have been adding better memory support, training behavior, and compatibility tuning through new BIOS releases. That work can make a large difference in how far a memory kit can be pushed.

For Colorful, the result also helps strengthen its iGame platform branding. Reaching 8600 MT/s on an AMD X870E motherboard shows that its board is capable of handling high DDR5 clocks with the right memory and processor pairing. For AMD systems, this is especially interesting because AM5 memory tuning has continued to improve across the 800 series motherboard generation.

This does not mean every CXMT based DDR5 kit will reach 8600 MT/s. Memory overclocking still depends on the motherboard, BIOS, memory controller, module quality, and cooling. Buyers should not treat this result as a guaranteed retail experience. Still, it is a strong sign that CXMT based memory is becoming more competitive.

The next clear target is 9000 MT/s. If CXMT modules can reach that range with stability, it would mark a major step for China’s domestic memory industry. For now, Colorful’s 8600 MT/s result shows that CXMT DDR5 is no longer limited to modest speeds and is starting to enter performance territory that would have seemed unlikely not long ago.
