OCCT lets you watch live sensors, run punishing workloads, and export evidence that your machine stays stable when it matters.
A trusted path to rock-solid hardware checks
OCCT loads every critical lane—CPU, GPU, memory, and power—with synchronized telemetry and audit-ready reports used by builders worldwide.
Tune CPU, GPU, RAM, and PSU scenarios with granular controls and catch silent faults before they reach production.
Follow temperature, voltage, clock, and load curves in real time with Hwinfo hooks and proactive overheat warnings.
Rank CPU and memory performance, then publish shareable stability certificates your team can trust.
Processor Torture Profiles
Multi-threaded engines surface throttling, voltage droop, and hidden errors long before everyday apps complain.
Graphics Pipeline Pressure
Adaptive 3D scenes and compute shaders hammer VRAM, shaders, and VRMs—exposing artifacts static benchmarks ignore.
RAM Integrity Drills
Pattern libraries, presets, import/export, and block-level control—built for overclockers, integrators, and data-sensitive rigs.
Whether you chase clocks, esports stability, sim rigs, or VR, OCCT keeps frames smooth when silicon runs hot.
