Colorful has pushed CXMT-based DDR5 memory to an impressive 8600 MT/s, showing that these memory chips are becoming far more capable than many expected. The achievement was made using Colorful’s iGame Shadow II DDR5 memory kit paired with the iGame X870E Vulcan motherboard and AMD’s Ryzen 9 9950X3D processor.
CXMT DDR5 memory has been gaining attention recently as motherboard and memory manufacturers continue to unlock higher speeds through BIOS updates and platform tuning. Not long ago, many DDR5 kits using CXMT chips were typically limited to around 6000 MT/s. That ceiling is now being pushed much higher, with several brands demonstrating major progress on AMD’s latest 800-series platforms.
Recent testing has already shown CXMT-based DDR5 memory running at 8200 MT/s on a B850 motherboard after a BIOS update. Another major motherboard maker later reached 8400 MT/s on an 800-series platform with updated firmware. Lexar has also entered the spotlight by announcing DDR5 memory kits using CXMT chips rated at 7600 MT/s with CL38 timings.
Now, Colorful appears to have raised the bar even further.
The company demonstrated its iGame Shadow II DDR5 memory kit running at 8600 MT/s on the iGame X870E Vulcan motherboard. The test system used AMD’s high-end Ryzen 9 9950X3D CPU, giving the setup a strong foundation for memory overclocking.
According to the validation screenshot, the DRAM frequency reached 4299.9 MHz, which translates to an effective DDR5 speed of 8600 MT/s. This makes it one of the fastest known results so far for DDR5 memory based on CXMT chips.
The memory configuration used was 2 x 16 GB, and the kit reportedly passed RunMemTestPro, suggesting that the overclock was not just a quick screenshot run but stable enough to complete memory stress testing. That is an important detail, especially at such high frequencies.
Even more interesting is that Colorful achieved this speed with CL46 timings. For DDR5-8600, that is a respectable timing configuration, particularly considering that CXMT-based DDR5 modules were previously viewed as more limited compared to established high-end memory chips.
This result is a strong sign that CXMT DDR5 memory is maturing quickly. Higher-speed kits based on these chips could become more common if motherboard vendors continue improving BIOS support and memory training on AMD’s newest platforms.
With 8600 MT/s now demonstrated, the next milestone could be 9000 MT/s. If CXMT-based DDR5 modules reach that level with stable operation, it would mark a major step forward for the company and increase competition in the high-performance DDR5 memory market.
For PC enthusiasts, overclockers, and system builders, this is an exciting development. Faster DDR5 memory can benefit bandwidth-sensitive workloads, high-end gaming systems, and performance-focused desktop builds. While real-world gains depend on the CPU, motherboard, timings, and application, the rapid progress of CXMT DDR5 shows that the memory market is becoming more competitive and more interesting.
