Tune it Your Way with ASUS AI Overclocking

Comprehensive AI Tuning suite Get the most out of your build with the ASUS AI Overclocking suite by automatically profiling your CPU and cooling system to predict optimal voltage and frequency settings. Accessible via the AI Suite software in Windows or directly through the UEFI, this intuitive AI Overclocking user interface enables users of all levels to optimise their setup how they see fit with a range of customizable settings for seasoned overclockers, or a simple auto-tuning option is available for beginners.

Expert Design

Designed by ExpertsAt the heart of AI Overclocking is an algorithm developed by a mixture of ROG research and development engineers and world-renowned overclockers to ensure the tool is suitable for users of all levels.

Predictive algorithm

Predictive EdgeThe AI Overclocking algorithm automatically analyses your CPU and cooling system to predict the optimal setting for your system. The software then uses these settings to automatically guide the clocking process, balancing frequency and voltage.

Real Time Adjustments

Real-Time AdjustmentsThe software monitors workload, system temperature, fan speed and power draw every minute and it makes real-time adjustments to ensure ongoing optimal performance.

Intelligent 5-way Optimisation

Overclocking made easier With a simple click ASUS 5-Way Optimization makes your PC smarter, it dynamically optimises essential aspects of your system, providing overclocking and cooling profiles that are tailored for your rig.

TurboV processing unit

CPU Performance BoostThe TurboV Processing Unit (TPU) is an intelligent system-tuning utility that can automatically fine-tune voltages, monitor system statistics, and adjust overclocking parameters for optimal performance.

Energy Efficiency

All-Around Energy efficiency The Energy Processing Unit (EPU) automatically optimises your power consumption and maximizes energy savings with a simple Away mode — a smart setting that creates an extreme energy-saving scenario by shutting down any unused I/O controllers.

Fan Expert 4

Flexible Air and Liquid Cooling ControlFan Xpert 4 software provides you with comprehensive control over fans, water pumps and all-in-one (AiO) coolers. Whether cooling with air or water, an Auto-Tuning mode intelligently configures all parameters with a single click. There’s also an Extreme Quiet mode that reduces all fan speeds to below the default minimum to keep your system whisper-quiet when performing light tasks. Fans, water pumps and AiO coolers can also be controlled via the UEFI BIOS.

Digital Power Control

Precise Digital Power ControlThe Digi+ voltage-regulator module (VRM) gives real-time control over voltage drop, automatically switching frequency and power-efficiency settings. It also allows you to fine-tune your CPU for ultimate stability and performance.

Application optimisation

Application Specific OptimisationTurbo App allows you to define CPU overclocking, apply fan profiles, prioritize network data and optimize audio settings at the app level, so your system is set up exactly as needed.

World Renowned UEFI BIOS

Not just for veteransThe renowned ASUS UEFI BIOS provides everything you need to configure, tweak and tune your system. It offers intelligently simplified options for PC DIY beginners, as well as comprehensive features for seasoned veterans.

Advanced Mode

Advanced Mode An intuitive Advanced mode offered via the UEFI lets you take complete control. A built-in search feature makes it easy to find options, and various Advanced functions let you intelligently make nuanced adjustments so you can dial in performance just the way you want.

Easy Mode

EZ(Easy) ModeEZ mode displays vital settings and stats and also offers guided wizards, drag-and-drop functionality, and one-click application of important settings — all to help you get your rig up and running in no time.

Artificially Intelligent Cooling

Self-Adaptive Fan Tuning ASUS AI Cooling function will automatically manage and control motherboard-connected fans to ensure optimal settings based on current system load and temperature.

CPU Temp Detection

Processor Temperature DetectionAI Cooling detects CPU temperatures and uses a proprietary algorithm to check the lowest fan speed required to effectively cool the system and keep fan noise and demand down.

Constant Monitoring

Constant MonitoringAI Cooling continues to monitor the system and adjust fan speed based on current demand.

Automated Optimisation

Automated OptimisationUnder stable system loads, the software then automatically lowers fan* speed to the optimal setting, decreasing fan noise without compromising performance.

Please Note

*Fans need to be connected to the following headers for AI Cooling control: CPU_FAN / CPU_OPT / CHA_FAN / M.2_FAN / H_AMP / RAD_FAN

Incredible Performance Needs Incredible Cooling

M.2 Heatsink

M.2 HeatsinkAn M.2 drive sits under a passive heatsink to ward off the throttling that can occur with continuous transfers. The heatsink is fixed in place by easily-removable captive screws, giving you the flexibility to move it to another M.2 slot.

VRM Heatsink

VRM Heatsink Two massive VRM heatsinks with underneath thermal pads improve heat transfer from the MOSFETs and chokes for better cooling performance. A bundled fan holder provides additional cooling options.

Get the Best Out of your Board

Robust Power Design

Robust Power DesignWith the Prime Series Z490 Motherboards ASUS have recognised that stable power is essential to squeeze every last drop of performance from your 10th Gen Intel CPU, the Prime Z490 is built to cater to the demands of high-core count CPUS with the addition of ProCool connectors that augment the motherboard's link to the PSU with 8+4 pin connectors that pass 12 volts of power directly to the processors and 12+2 DrMOS Power Stages that are capable of delivering the power and efficiency that the latest generation of intel CPUs Demand.

Optimise your Memory with ASUS OptiMem II

Optimem II

Revisions to Trace Routing The Z490 Prime Motherboards now provide unrestricted access to memory bandwidth for 10th Gen CPUs by making some revisions to the motherboards trace routing. ASUS OptiMem II technology carefully maps memory signal pathways across different PCB layers to reduce vias and adds shielding zones that significantly reduce crosstalk.

Lightning Fast Storage with Dual M.2

Dual m.2

Faster booting and app load times Dual M.2 slots support data-transfer speeds of up to 32 Gbps via x4 PCI Express® 3.0 bandwidth, enabling quicker boot-up and app load times with OS or application drives.

ASUS SafeSlot Protection

safe slot core

PREMIUM ASUS TECHNOLOGY SafeSlot Core is the ASUS-exclusive PCIe® slot. Featuring a fortified design that's anchored to the motherboard by a special hook, Safeslot Core provides 1.6X-stronger retention and 1.3X-greater shearing resistance than standard expansion slots. ASUS Prime motherboards have strengthened solder points around both the PCIe and DIMM pins.

Outshine the Competition with ASUS Aura Sync

Your Motherboard, Your Way 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 and devices connected to the onboard RGB headers - and it can all be synced with an ever-growing portfolio of Aura-capable hardware.

 Very good BIOS interface by Mai

I bought this motherboard to replace an aging Ivy Bridge system and paired it with an i5 10600k. The motherboard is excellent and supports SLI, which is rare for something in this price range.
