AI Cache Boost optimizes CPU cache and memory pathways to accelerate local large language model (LLM) workflows. Exclusive to ASUS AMD 800 and 600 series motherboards using Ryzen™ 9000 Series CPUs, this BIOS setting can deliver up to 29% faster local LLM performance when combined with high-speed memory tuning. The feature reduces the performance drop that occurs when VRAM is exhausted and benefits further from high-speed DDR5 and Infinity Fabric (FCLK) tuning.

The 3D vapor-chamber M.2 heatsink provides a significantly larger dissipation area connected to extended heat pipes and a temperature-equalization plate to form a vacuum chamber. This design notably improves cooling for PCIe 5.0 M.2 SSDs and lists Operating Temperature as 10% Cooler, while remaining highly efficient with air-cooling compatibility.
