AI Cache Boost is a BIOS setting exclusive to ASUS AMD 800 and 600 series motherboards with Ryzen™ 9000 Series CPUs. It optimizes CPU cache and memory pathways to improve local LLM performance — delivering up to 29% faster local LLM performance with high-speed memory tuning and showing up to a 15% uplift in tests when VRAM was exhausted, which can nearly double with high-speed DDR5 and FLCK tuning.
