AI Overclocking

ASUS AI Overclocking makes automatic tuning faster and smarter than ever before. Available in Windows or directly through the UEFI, it profiles the CPU and cooling to predict the optimal configuration for each individual system.

CPU Potential

A proprietary algorithm evaluates the capabilities of your CPU

Cooling Capability

Onboard intelligence watches system vitals such as temperature, fan speed, and power draw to gauge cooling performance

5-Way Optimisation

One click takes care of all that complex tuning. ASUS 5-Way Optimisation makes your PC smart. It dynamically optimises essential aspects of the system, providing overclocking and cooling profiles that are tailored for your rig.
An automated tuning utility that optimises overclocking and cooling profiles for your unique system configuration.
Fans stay quiet as a whisper for everyday computing, and deliver optimal airflow when the system is crunching through CPU or GPU-intensive tasks.
All-new stress test that allows users to optimise and overclock for CPU or memory-centric workloads.

CPU performance boost

The TurboV Processing Unit (TPU) is the intelligence behind our automated system-tuning utility, offering the ability to fine-tune voltages, monitor system stats, and adjust overclock parameters for optimal performance.

All-round energy efficiency

With the Energy Processing Unit (EPU) you'll enjoy system-wide power savings. The EPU automatically optimises power consumption and maximises savings with Away mode — a smart setting that creates an extreme energy-saving scenario by shutting down unused I/O controllers.
