      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 Optimization

      One click takes care of all that complex tuning. ASUS 5-Way Optimization makes your PC smart. It dynamically optimizes essential aspects of the system, providing overclocking and cooling profiles that are tailored for your rig.
      An automated tuning utility that optimizes 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 optimize 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 optimizes power consumption and maximizes savings with Away mode — a smart setting that creates an extreme energy-saving scenario by shutting down unused I/O controllers.

      Flexible cooling controls for air or liquid

      With Pro WS X299 Sage II you have comprehensive control over fans via Fan Expert 4 or our media-acclaimed UEFI. Whether you're cooling with air or water, Auto-Tuning mode intelligently configures all parameters with a single click. There's also an Extreme Quiet mode, which reduces all fan speeds to below the default minimum — keeping your system whisper-quiet when performing light tasks.

      Precise digital power control

      Digi+ delivers real-time control over voltage droop, switching frequency and power -efficiency settings, allowing you to fine-tune CPU voltage regulation for ultimate stability and performance.

      Optimize per-core performance for every app

      Intel's latest processors feature per-core tuning, and the ASUS Turbo Core app makes use of this feature by enabling you to assign applications to specific processor cores, allowing you to prioritize compute power where it's needed most.
