AI Overclocking at a Glance

Designed by Experts

At the heart of AI Overclocking is a proprietary algorithm developed by ROG R&D engineers who worked with world-renowned overclockers to create a tool for users of all levels.

Predictive Edge

The algorithm analyzes your CPU and cooling system, and based on what it finds, predicts optimal settings. The software then uses these settings to automatically guide the clocking process, balancing frequency and voltage.

Real-time Adjustments

The software monitors workload, system temperature, fan speed and power draw every minute and it makes real-time adjustments to ensure ongoing optimal performance

AI Overclocking Guide

The AI Overclocking Guide provides detailed information and instructions about how to tune your system manually. It can be accessed by hitting the F11 hotkey.

Core Group Loading

For high-core count processors like the Z490, AI Overclocking lists data according to core group. This gives you adaptive control based on the status of core groups (3 / 5 / 8 / all cores), and it provides target frequency and voltage estimations needed for manual tuning.

AI Overclocking in AI Suite

Onboard intelligence lets you automated overclocking with full, flexible control available via 5-Way Optimization within AI Suite (in Windows).

AI Cooling

ASUS AI Cooling function will automatically manage and control motherboard-connected fans to ensure optimal settings based on current system load and temperature.

Self-Adaptive Fan Tuning

CPU Temperature Detection

AI Cooling detects CPU temperatures and uses a proprietary algorithm to calculate the lowest fan speed required to effectively cool the system and keep fan noise down.

Automated Optimization

Under stable system loads, the software then automatically lowers fan* speed to the optimal setting, decreasing fan noise without compromising performance.

Ongoing Monitoring

AI Cooling continues to monitor the system and adjust fan speed based on current load.
