CPU performance boost

Unleash your PC's full performance with the ASUS AI Suite 3 utility. 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 Prime Z370-A you have comprehensive control over fans, water pumps, and even all-in-one (AIO) coolers ― all via Fan Xpert 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 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.

App specific optimization for professionals and gamers

Whether you're a professional designer or hardcore gamer, you'll feel the benefit of the ASUS-exclusive Turbo App. This intuitive tool allows you to define CPU overclocking, apply fan profiles, prioritize network data and optimize audio settings at app level ― so your Prime Z370-A system is perfectly optimized for whatever you're doing.

Make your memory go faster

ASUS OptiMem preserves memory signal integrity by routing memory traces and vias to the optimal PCB layer, and our T-Topology layout ensures time-aligned signaling by balancing trace lengths between memory slots. These enhancements lead to more headroom for overclocking and improved stability, allowing memory speeds of DDR4-4000 and beyond with all slots populated.
