PSU rails under fire
Burn-in harness
Tune duration, threads and algorithms per device, then let OCCT flag micro-errors in CPU, GPU, memory and power paths before they become crashes.

Inside the OCCT workload library
Built for repeatable, measurable burn-in
Mimic real game load swings
Adaptive 3D load
Adaptive 3D mode ramps shader load up and down to mimic menu idle, cutscenes and heavy scenes—surfacing driver or thermal weak spots.

Charts that never lag the test
Sensor streaming
Watch temps, voltages, clocks and utilization on synchronized charts powered by HwInfo so you trust every reading during a run.
Wire up monitoring
Quantify silicon headroom
Metrics scoring
Onboard cache and memory latency benchmarks make before/after tuning comparisons objective instead of gut feel.
Open benchmark panel
Full control
User-defined sequences
Granular control over durations, intervals, memory presets and multi-GPU workflows for professional hardware validation.
Memory test guide
Rock-solid proof of stability
Run diffs
Quickly identify differences between reports, from CPU throttling and fan anomalies to badly configured memory timings.
