AI Cache Boost is an ASUS BIOS setting exclusive to ASUS AMD 800 and 600 series motherboards using Ryzen™ 9000 Series CPUs. It optimizes CPU cache and memory pathways to improve local LLM workflows, with materials showing up to 29% faster local LLM performance when combined with high-speed memory tuning.

Dynamic OC Switcher automatically optimizes CPU performance by letting you define current and temperature thresholds to switch between a manual overclock for heavy multithreaded workloads and Precision Boost Overdrive for single-threaded tasks. The feature includes enhanced instantaneous current protection (Overclocking Load Guard) to reduce crash risk during aggressive tuning. For example, a shown threshold uses >35A to engage manual OC and returns to PBO when temperatures reach 80°.
