ASUS Preps AM5 BIOS Updates to Cut CXMT DDR5 Memory Latency

ASUS is rolling out beta BIOS updates for AM5 motherboards across AMD 600 and 800 series (X870, B850, X670, B650), based on AGESA ComboAM5 PI 1.3.0.1d. The builds add optimized low-latency support for DDR5 modules using CXMT chips via memory training and subtiming tuning.

• Beta BIOS targets X870, B850, X670 and B650 boards on AGESA ComboAM5 PI 1.3.0.1d
• Tuning focuses on memory training and subtimings for CXMT DDR5 kits
• CXMT modules have already hit around 9000 MT/s on X870E boards
• ASUS has not published benchmark figures for the latency gains yet
