Our story

Passion and dedication

2003

Born... in the USA

OCCT, short for “OverClock Checking Tool”, began as an experiment during a student exchange in Oklahoma back in 2003.

Driven by a desire to stress-test overclocked PC builds, Adrien Mercier developed OCCT's very first test, which quickly gained popularity across online forums within the overclocking community.

2004 - 2019

The passion project

After returning to France, OCCT's creator began a career in IT as a system administrator, all while continuing to develop OCCT in his free time.

Despite professional commitments and major life events, OCCT continued to receive regular updates, driven by passion and countless late-night coding sessions.

2020 - 2023

Going all in

As the 2020s began, OCCT went through a major code overhaul and gained even more traction among PC enthusiasts.

The Covid pandemic presented an unexpected opportunity to take OCCT to the next level, transforming it into a full-time endeavor.

2024 - 2025

A new frontier

Backed by a rapidly growing team, OCCT adopted a refreshed visual identity, expanded its suite of professional features, and launched on Linux.

Today

To infinity and beyond

OCBASE thrives on innovation and the pursuit of cutting-edge solutions for OCCT users, while staying deeply rooted in its origins: the community.
