Overclocking expert der8auer recently video So he stepped into Intel’s OC labs to see how the company tests its unlocked processors. In the video he reveals a secret called Real Time Overlocking (ROC) that he used to stably push the mobile Core i9-13900HK up to 5.8GHz before the system crashed at his 6GHz. showed off the Intel overclocking application.
In der8auer’s own words, the ROC app is a stripped-down version of Intel’s XTU program. He likes his XTU much better than his XTU, and says the interface is much more intuitive than his XTU.
Application is very easy. The main page has a section called “Per-Core Ratio and AVX Offset” which has a very simple interface that shows all the cores in the CPU as boxes. The user can then hold left click and drag the mouse over the core to be overclocked. On the right is the core ratio slider and his CPU multiplier offsets for AVX2, AVX512 and his TMUL.
Moving to a tab in the application called “Active-Core Ratio” gives users direct control over individual CPU core multipliers for more fine-tuned overclocking. Next to it is another tab called “V/F Override” that allows users to control the voltage of individual cores or all cores at once. You can also change the voltage target mode here to be fixed override voltage or adaptive voltage.
For reference, this is very similar to manually overclocking an Intel desktop CPU. Manual voltage forces the CPU to operate only at a predefined voltage set by the user, while adaptive voltage forces the CPU to operate at a predefined user voltage when running at maximum clock speed. to improve power consumption at low loads.
These are just a few of the things the app can do. There are many more features the app offers, such as manipulating Intel Turbo Velocity Boost, power capping, and more.

5.8GHz overclock
Der8auers’ 5.8GHz overclock was achieved on an Intel engineering motherboard with a simple air cooling solution (very different from the high-end LN2 overclocking gear we’re used to seeing). Nonetheless, the CPU temperature was excellent, reaching 65-75 degrees Celsius during overclocking, with a core voltage of almost 1.5 volts.
Overclocking was done entirely in ROC. The der8auer went from 4.9GHz to 6GHz in just 3 minutes he stepped up in 200MHz increments and the chip stabilized he hit 5.8GHz before the rig froze at his 6GHz mark.
Nonetheless, the results are impressive. According to der8auer, this is the highest frequency he’s seen on his chip for mobile cooling solutions (including dry ice) to date.
