ASUS Z390 Series Feature Manual
The rst step is loading the UEFI defaults by pressing F5, and then F10 to save and reboot.
This establishes a stable baseline so that AI OC can evaluate your system. Next, boot into
the operating system and run a stress test. You can use Blender, Prime95, Aida64, ROG
RealBench, the Intel Extreme Tuning Utility, or anything else that loads up the CPU. AI
Overclocking is better able to determine the limits of your machine with longer and more
intensive workloads, but that doesn’t mean you need to settle in for a full day of stress
testing. I chose to use Intel XTU and set the test for 30 minutes, which is long enough to get
the system’s blood pumping.
Once the test nished, I headed back to the BIOS and navigated to the AI Tweaker section.
Setting the CPU Core Ratio to AI Optimized is all that’s required to enable AI Overclocking.
The automated intelligence gave our system cooling a score of 175 and rated our CPU’s Sil
Quality at 72%. It predicted an optimal all-core clock speed of 5.2GHz, which is an impressive
800MHz higher than the chip’s default frequency when fully loaded. AI Overclocking applies
its optimized settings automatically, so all you have to do is hit F10 to save and reboot.
After saving the AI Overclock cong, I headed back to the desktop to check stability with
another stress test. The system passed with ying colors. Although the CPU temperature
briey reached 80°C, it averaged only 69°C for the entirety of the 30-minute Intel XTU stress
test.
And ... That’s all. The process is really easy, and predictions are generated almost instantly.
The entire procedure barely took longer than the hour we spent on stress tests. Longer
stress tests can provide a more accurate read on your system’s limits, but you can also use
a shorter test to get a quick assessment and then rely on continuous training to hone the
prediction.
