Colorful iGame Shadow II DDR5 Hits 8600 MT/s, Beating MSI and ASUS

Colorful has pushed CXMT-based DDR5 memory to a new performance ceiling, reaching 8600 MT/s. This milestone matters because it proves Chinese memory chipmakers have matured enough to compete with top-tier global speeds. Buyers tracking high-frequency RAM upgrades now have a viable path to record-breaking stability.

New stability milestone for Chinese memory chips

The record-breaking run utilized the iGame Shadow II DDR5 memory kit installed on Colorful’s own iGame X870E Vulcan motherboard. The system relied on an AMD Ryzen 9 9950X3D processor to drive the memory controller. This specific hardware combination allowed the memory to operate at a DRAM frequency of 4299.9 MHz.

Specifications

• Memory Speed: 8600 MT/s
• Memory Capacity: 2x 16 GB
• Memory Latency: CL46
• Motherboard: iGame X870E Vulcan
• CPU: AMD Ryzen 9 9950X3D

Colorful achieved this speed using a 2x 16 GB configuration with CL46 latency. The memory modules passed RunMemTestPro stability checks without errors, confirming the reliability of the setup. The CXMT DDR5 chips inside the kit appear robust enough to handle these extreme overclocking parameters.

This achievement surpasses previous CXMT DDR5 records set by MSI at 8200 MT/s and ASUS at 8400 MT/s. Lexar had previously announced CXMT kits capable of 7600 MT/s, but Colorful has now broken that barrier as well. We looked at MSI BIOS Update Unlocks DDR5-8200 for earlier while tracking Colorful launches.

Colorful’s iGame Shadow II DDR5 kit now holds the official speed record for CXMT-based memory on the AMD 800-series platform. The company demonstrated that its tuning capabilities can extract maximum performance from domestic silicon. This sets a new benchmark for future high-speed memory configurations.
