Intel’s Unreleased Overclocking App Pushes Mobile Core i9-13900HK to 5.8GHz
Overclocking expert der8auer recently published a video where he visited Intel’s OC lab to see how the company tests its unlocked processors. In the video, he showed a confidential Intel overclocking application – called Real Time Overlocking (ROC), which he used to stably push a mobile Core i9-13900HK up to 5.8GHz before the system crashed at 6GHz.
In der8auer’s own words, the ROC application is a stripped down version of Intel’s XTU program. He says he much prefers it over XTU, and the interface is also much more intuitive compared to XTU.

The application is quite simple. On the main page there is a section called “Per-Core Ratio and AVX Offset,” and you have an incredibly simple interface that shows all the cores in the CPU as boxes. The user can then hold a left click and drag the mouse over which cores they want to overclock. On the right, there’s a core ratio slider, as well as CPU multiplier settings for AVX2, AVX512, and TMUL.
By moving over to the tab in the app called “Active-Core Ratio,” users gain access to direct control over individual CPU core multipliers, for more fine-tuned overclocking. Next to this is another tab called “V/F Override,” which allows the user to control the voltage of individual cores, or all the cores at once. You can also change the voltage target mode here, to be either a fixed override voltage or adaptive voltage.
For reference, this is very similar to manually overclocking Intel desktop CPUs. Manual voltage will force the CPU to only operate at a preset voltage set by the user, while adaptive voltage will only turn on a user preset voltage when the CPU is running at its maximum clock speed, improving power consumption at low loads.
These are just a few things the app can manipulate. There are even more capabilities the app can offer, including manipulation of Intel Turbo Velocity Boost, power limits, and more.

Der8auer’s 5.8GHz overclock was achieved on an Intel engineering motherboard with a simple air cooling solution (hardly the high-end LN2 overclocking gear we’re used to seeing). Despite this, CPU temperatures were excellent, only hitting 65-75 Celsius while overclocking, with a core voltage of nearly 1.5 volts.
The overclocking was done entirely in ROC; der8auer moved up from 4.9GHz to 6GHz in 200MHz increments over the course of just three minutes, with the chip managing to stably hit 5.8GHz before the rig froze at the 6GHz mark.
Nevertheless, this result is still impressive; der8auer says this is the highest frequency he has ever seen from a mobile chip on any cooling solution (including dry ice).
