AI OC has been with us for several generations. However, over the years, it's evolved so much that even avid overclockers cannot ignore the benefits of consulting ROG AI features. Keep reading to see what you may have been missing and why AI OC is no longer about automation and more about information!


AI Features
If you have never used AI OC, you might have neglected to peruse the AI Features menu under Extreme Tweaker

Intel Setups

P0 Frequency: This is our highest frequency observed at stock.

SP: This is our score weighting based on P0 VID, temperatures and maximum boost frequency on individual cores.

Set by P-Core Loading: This is the P-Core frequency suggested under different active P Core conditions:



The above example would look like this when defined manually within Per Core Loading:



Set by E-Core Loading: Similarly, this is the E-Core frequency suggested under different active conditions:


 The above example would look like this when defined manually within Per Core Loading. Notice here that we also have to define our core groups manually.




Set Specific Core is our P-Core Specific Core Predictions for assigning a specific core frequency to individual performance cores, ordered from the first P-Core till the last P-Core.

Set Adaptive Voltage Is our overall Adaptive Voltage calculated for our AI Optimized Settings. Certain Cores may be opportunistically set to a lower voltage individually.

Set SVID Behaviour is our desired SVID Behaviour for our AI Optimised Settings. Trained SVID optimises SVID behaviour to match input parameters such as VRM Loadline and Target Frequencies.

Set Temperature Regulator is our desired setting for AI temperature regulation. When enabled, it will monitor our parameters and adjust the overclock dynamically depending on our thermal headroom.

MC (Memory Controller) SP is the SP score for the memory controller and can be invaluable when binning processors for memory controller strength, saving hours of testing. It does this by testing the FMax (Frequency Max) of the IMC by applying a low fixed VCCSA (CPU System Agent) voltage.

The test result can be influenced by temperature; however, ASUS takes this into account and the score is weighted by the maximum package temperature of the CPU. Expect it to sway 1-3 points between tests within a margin of error for this reason. A typical score is between 70-75 points. Less than 65 can be considered below average and higher than 80 is a strong IMC.

Note: The MC SP score is not influenced by an applied memory overclock or which memory is installed in the system. The tests do not address the DRAM, only the CPU's memory controller.


Get MC SP will reboot the system and take a few moments to run a series of training tests on the CPU. Upon returning to the UEFI, the score will be on the same page (AI Features).



Predictions Overviews

The Hardware Monitor tab is situated on the right-hand side of the screen and gives us an advanced overview. After putting a load on the CPU, we can see our overall SP score considering both P-Core and E-Core weighting and our current cooler points based on thermal performance.

Beneath this, we can see our desired load voltage and frequency for light and heavy workloads, including cache. The desired voltage will change dynamically depending on the applied Loadline Calibration.




Processor Utilization Journal

We can now also track the system behaviour over time. AI Optimized features are able to make adjustments based on the age of the processor and utilisation information. It can also be useful for tracking the system’s power efficiency.




AMD Setups


Platform Tools: PPT, TDC, and EDC: These allow for higher frequencies to be maintained over a longer duration

Fmax Offset: Increases the frequency ceiling of the CPU enabling higher clocks under low current light loads.

Scalar: Allows adjustment of the reliability/stability concerns, enabling the use of higher core voltages.

Curve Optimiser: Here we can apply an offset based on the stock Voltage Frequency Table, changing the applied VID at a given frequency-temperature point.

OC Mode:  Prefable for per CCX tuning for maximum stable all core frequency (under high current loads)

Precision Boost Overdrive: Default Boost algorithm beneficial for single-threaded or light workloads, achieving the highest core frequency.
Dynamic OC Switcher: Allows for switching between PBO2 and OC Mode in order to maximise performance for both light and heavy workloads.




 ⦁ Curve Optimizer values: Values to be defined for individual cores for potential undervolting.

Set FMax Limit:  Absolute Maximum Frequency Cap override.

Set Scalar to: Also known as FIT (Failures in Time) Scalar magnitude, increasing this is suggested in order to raise the Processor’s Boosting capabilities based on a stability scale.

Set Curve Optimiser to:  The recommended frequencies of each chip-let when the processor enters OC Mode defined by Set CCDx Ratio to.

Set OCVID to: The recommended overall voltage is associated with the aforementioned frequency when the processor enters Overclock Mode.

Set DOS to: The recommended Dynamic OC Switcher setting

Set DOS Current Threshold to: The recommended Current threshold at which the processor will transition into OC Mode using Dynamic OC Switcher setting.

Set Medium Load Boostit: Whether or not to enable Medium Load Boostit which may improve performance under medium stressful conditions such as gaming.





Information is power!

All this information makes overclocking our CPU a breeze. We do not have to be looking for "One Click" overclocking to take advantage of AI Features. Access to tools that gauge things such as the strength of our CPU cores and IMC can save even experienced overclockers hours of work, so make sure to check them out even if you do not plan to use autonomous overclocking.
