Power delivery enhancements
DR. MOS
The Prime Z370-A II's CPU VRM utilizes Dr. MOS power stages that combine high-side and low-side MOSFETs and drivers into a single package, delivering the power and efficiency that Intel's latest processors demand.

ProCool power connector
Compared with traditional power inputs, ProCool sockets are built to tight specifications to ensure flush contact with the PSU power lines. This lowers impedance, which helps to prevent hotspots and connector failure.

Tune it your way
5-Way Optimization
One-click overclock and cooling, done!
ASUS 5-Way Optimization makes your PC smart. One click takes care of complex tuning, dynamically optimizing essential aspects of the system to provide 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 whisper-quiet with everyday computing, and deliver optimal airflow when the system is crunching through CPU or GPU-intensive tasks.
- Stress test function helps optimize and overclock for CPU- or memory-centric workloads.

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.

OC Design – ASUS Pro Clock Technology
PRIME Z370-A II includes a dedicated base-clock (BCLK) generator that extends CPU and memory overclocking margins. This custom solution works in tandem with the TPU to enhance voltage and BCLK overclocking control, providing the flexibility to extract every ounce of performance from the Intel Core 8th Generation processors.

Cooler by design
PRIME Z370-A II features the most comprehensive cooling controls ever, configurable via Fan Xpert 4 or the UEFI BIOS.

ASUS Fan Holder
With the all-new ASUS Fan Holder increasing airflow your Prime Z370 Series motherboard's VRM area is simple. Just screw on a 40/50mm fan, mount the bracket on the heatsink, and hook the fan up to a header for a targeted cooling boost. With the Fan Holder and fan in place, VRM temperatures are reduced by up to 25oC — perfect for your overclocking adventures.

Media-acclaimed UEFI BIOS
The smoothest, slickest mouse-controllable graphical BIOS has been improved to make it even more appealing. Whether you're a PC novice or a seasoned overclocker, EZ and Advanced modes will help you quickly find your way, quickly and easily.
