OCCT v16.1 goes stable with Intel Arrow Lake Refresh CPU tuning support

OCCT v16.1 for Core Ultra 200S and 200S Plus

OCCT has released version 16.1 as a stable update, adding Intel Arrow Lake CPU support to its System Tuning tool. The company also says the feature extends to Arrow Lake Refresh , moving the functionality out of open beta less than two weeks after the earlier preview build.

The update is centered on OCCT’s System Tuning feature, which combines CPU tuning and stability validation in the same application. According to OCCT, users can adjust CPU settings directly inside the software, run stability tests during tuning, and work on both Windows and Linux. Arrow Lake platforms also get per-core frequency control in 16.6 MHz steps.

This is the next step after OCCT announced a collaboration with Intel around a new processor tuning tool. The feature first became available in OCCT v16 with support for Granite Rapids, and the company then introduced Arrow Lake support in an open beta on March 11.

OCCT says it plans to keep expanding System Tuning support to more current and older CPU generations. For now, v16.1 marks the first stable release of the tool with Arrow Lake support, after the feature was still labeled as beta earlier this month.
