AI Overclocking at a Glance

Designed by Experts

At the heart of AI Overclocking is a proprietary algorithm developed by ROG R&D engineers who worked with world-renowned overclockers to create a tool for users of all levels.

Predictive Edge

The algorithm analyzes your CPU and cooling system and, based on what it finds, predicts optimal settings. The software then uses these settings to automatically guide the clocking process, balancing frequency and voltage.

Real-Time Adjustments

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

AI Overclocking in AI Suite

Onboard intelligence offers automated overclocking with full, flexible control available via Easy Optimization within AI Suite (in Windows).

AI Overclocking Guide

The AI Overclocking Guide provides detailed information and instructions about how to tune your system manually. It can be accessed by hitting the F11 hotkey.

Core Group Loading

For high-core-count processors, AI Overclocking lists data according to core group. This gives you adaptive control based on the status of core groups, and it provides target frequency and voltage estimations needed for manual tuning.

AI Cooling

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

Self-Adaptive Fan Tuning

CPU Temperature Detection

AI Cooling detects CPU temperatures and uses a proprietary algorithm to calculate the lowest fan speed required to effectively cool the system and keep fan noise down.

Automated Optimization

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

*Fans need to be connected to the following headers for AI Cooling control: CPU_FAN / CPU_OPT / CHA_FAN / W_PUMP+/ AIO Pump

Ongoing Monitoring

AI Cooling continues to monitor the system and adjust fan speed based on current load.

COOLING

Prime Z690 series is engineered with multiple onboard heatsinks and an array of hybrid fan headers to ensure your rig stays cool and stable under intense workloads.

• Heatsinks
• Cooler by Design

M.2 Heatsink

Two M.2 heatsinks take care of the three M.2 slots, warding off throttling that can occur with M.2 storage during sustained transfers.

Removable captive screws reduce risk of drops or loss during heatsink removal.

VRM Heatsink and Thermal Pads

The two VRM heatsinks on Prime Z690-A are significantly larger than those found on earlier Z590 motherboards. Together with the thermal pads, they improve heat transfer from the MOSFETs and chokes for better cooling performance.

M.2 Backplate

An M.2 backplate helps ensure that high-performance drives deliver peak performance, even when airflow is restricted. The backplate includes the Q-Latch mechanism to allow you to secure or remove an M.2 SSD without the need for traditional screws.

Cooler by Design

Prime Z690 series features comprehensive cooling controls that are configurable via Fan Xpert 4 software or via the UEFI BIOS.

• Multiple Temperature Sources

Each header can dynamically reference three thermal sensors. Fan Xpert 4 allows you to map the temperature of supported ASUS graphics cards to optimize cooling for GPU- and CPU-intensive tasks.

• Dual-Pump Headers

A dedicated header supplies over 3 amps* for high-performance PWM or DC water pumps, plus a second dedicated header for AIOs.

*AIO Pump header supports 1 amp, and Water Pump+ header supports 3 amps.

• Smart Protection

A dedicated integrated circuit protects each fan header from overheating and overcurrent.

• 4-Pin PWM/DC Fan

Each onboard header supports auto-detection of PWM or DC fans.

PERFORMANCE

Prime Z690 series is built to handle the additional cores and increased bandwidth of 12th Generation Intel® processors. ASUS Z690 motherboards provide all the fundamentals to boost daily productivity, so your system will be ready for action with stable power, intuitive cooling and flexible transfer options.

Robust Power Design

Stable power is essential to extract every last bit of performance out of 12th Generation Intel® processors. Prime Z690-A is geared to cater to the demands of these high-core-count CPUs.

ProCool Connectors

Proprietary connectors augment the motherboard's link to the PSU with 8+8 pin connectors that pass 12 volts of power directly to the processors. Each jack features solid pins that can handle more current than hollow-pin connectors.

16+1 DrMOS

A VRM with 16+1 DrMOS delivers the power and efficiency that the latest Intel processors demand.

DDR5 Performance Enhancement

Prime Z690-A enhances DDR5 performance by providing overclocking options for not only high-speed kits, but even entry-level memory modules that have a locked power management IC (PMIC).

• A dedicated circuit on the motherboard safely circumvents DDR5 memory PMIC restrictions, allowing you to step past the default 1.1-volt limit and push frequency and timings to the max.
• Ordinarily, a restricted PMIC that has been unlocked requires the system to be fully power-cycled each time memory voltage is adjusted. Prime Z690-A leverages onboard hardware and firmware to cleverly work around this irksome limitation, enabling voltage adjustments to be applied through the same soft system-reset process employed for previous generations of DDR memory.

For users new to memory overclocking, Prime Z690-A includes the exclusive ASUS Enhanced Memory Profile (AEMP) firmware feature for PMIC-restricted memory modules. AEMP automatically detects the memory chips on your kit and then presents optimized frequency, timing and voltage profiles that you can effortlessly apply to unleash performance.

ASUS OptiMem II

Revisions to the motherboard’s trace routing provide the latest Intel processors with unrestricted access to memory bandwidth. ASUS OptiMem II technology carefully maps memory signal pathways across different PCB layers to reduce vias and adds shielding zones that significantly reduce crosstalk.

Benefits of ASUS OptiMem II:

• Improved memory stability and compatibility
• Allows lower memory latencies at equivalent voltages
• Improved memory frequency margin

Motherboards with OptiMem II technology were tested with Synopsys HSPICE simulation software
