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
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.
AI Overclocking Guide The AI OC Guide allows you to enable the AI Overclocking or view a quick guide.
Prediction AI Overclocking monitors system vitals like power draw, temperatures, and fan speeds to gauge overclocking performance.
Cooler by design
Prime Z390-A features the most comprehensive cooling controls ever, configurable via Fan Xpert 4 or the UEFI BIOS.
Each header can dynamically reference three thermal sensors, and via Fan Xpert 4 you can even map the temperature of supported ASUS graphics cards to optimize cooling for GPU and CPU-intensive tasks.
Keep your SSD cooler
Prime Z390-A has an ultra-efficient heatsink to reduce M.2 SSD temperatures by up to 20°C — and that means optimal storage performance and improved SSD longevity.
Outshine the competition
A well-tuned enthusiast system deserves a matching aesthetic. ASUS Aura offers full RGB lighting control with a variety of functional presets for the built-in RGB LEDs as well as strips connected to the onboard RGB headers.* And it can all be synced with an ever-growing portfolio of Aura-capable ASUS hardware.
