    Dressed in professional attire, the Prime Z390 series caters to daily users and content creators with well-rounded specs and features. Combining the benefits of the latest processors with essential ASUS design and engineering, Prime Z390 provides a wealth of options for performance tuning via intuitive software and firmware features.

    Tune it your way

    Prime Z390 simplifies CPU overclocking with software and extensive tweaking options that give beginners and seasoned overclockers alike the tools to build well-tuned machines. A new memory trace layout provides stability and compatibility for both traditional DIMMs and RGB-infused memory, letting you pair a broad choice of DRAM kits with your build.

    Intelligent Control

    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

    We created a proprietary algorithm that evaluates the capabilities of your CPU

    Cooling Capability

    The onboard intelligence also watches system vitals like temperatures, fan speeds, and power draw to gauge cooling performance

    AI Overclocking

    Utilizes onboard intelligence to perform automated clocking and provides target frequency and voltage estimations for savvy veterans that prefer manual tuning

    5-way Optimization

    Overclocking Intelligence

    Take care of complex tuning with just one click. ASUS 5-Way Optimization is a system-wide tuning utility that overclocks the processor and tunes fan speeds to ensure the best balance between cooling and acoustics. The automated CPU tuning feature of 5-Way Optimization leverages the same onboard intelligence as AI Overclocking, but goes further by running a Prime95 based stress test to deliver a result that's well-tuned from the get-go.

    Media-acclaimed UEFI BIOS

    The UEFI BIOS is an early waypoint on any PC-building journey, and Prime Z390-A offers one of the best in the business.
