EXPO 1.2 only brings partial CUDIMM support due to lack of native IMC compatibility — Asus also working on updating older B650 and X670 boards with EXPO 1.2
EXPO 1.2 has been released with partial CUDIMM support, limited to 6,000 MT/s due to lack of native IMC compatibility in current Ryzen CPUs. Asus is rolling out the update to newer X870 and B850 boards, with plans to extend support to older B650 and X670 models via BIOS updates. Full CUDIMM functionality is expected with next-gen Ryzen processors based on Zen 6. The update also introduces Ultra-Low Latency mode and improved module geometry recognition.
- ▪EXPO 1.2 enables partial CUDIMM support, capping speeds at 6,000 MT/s despite the modules' potential for up to 9,000 MT/s.
- ▪Current Ryzen 7000, 8000G, and 9000 series CPUs lack native CUDIMM support, requiring bypass mode for system stability.
- ▪Native CUDIMM compatibility is planned for future Ryzen CPUs based on the Zen 6 architecture.
- ▪Asus is developing beta BIOS updates to bring EXPO 1.2 features to older B650 and X670 motherboards.
- ▪EXPO 1.2 also adds Ultra-Low Latency mode, reducing DDR5 latency by 5–7 nanoseconds, and improves support for memory module geometry.
