OCCT has released version 16.1 as a stable update, bringing full support for Intel Arrow Lake CPUs to its System Tuning tool. The company moves this feature out of open beta just weeks after its preview, which shows how quickly it refined the experience for early users. This update focuses on giving users more control over CPU tuning and stability testing inside one application.
The System Tuning feature lets users adjust CPU settings directly in OCCT, run stability tests while tuning, and work across both Windows and Linux systems. OCCT says the tool “combines CPU tuning and stability validation in the same application,” which helps users test changes in real time instead of switching between tools. Arrow Lake systems also gain per-core frequency control in precise 16.6 MHz steps, giving users tighter control over performance.
According to OCCT, this release builds on its collaboration with Intel around a new processor tuning tool. The company first introduced support in version 16 with Granite Rapids CPUs and later added Arrow Lake in an open beta on March 11.
OCCT says it will continue to expand System Tuning support to more processors. Version 16.1 now marks the first stable release with Arrow Lake support, moving beyond its earlier beta status and setting the base for broader CPU compatibility.
