Scanner output is a hypothesis printed as a graph

OC Scanner samples your GPU under a bounded workload and suggests a voltage-frequency relationship. That snapshot is not identical to a long ray-traced evening, a VR session, or a compile storm. Use it to seed a curve, then prove stability with workloads you personally care about.

OC Scanner with MSI Afterburner: honest limits

Five-minute preconditions that matter

Settle on a driver branch you plan to keep for a week. Note case intake condition and ambient room temperature. If the card already thermal-throttles in light loads, Scanner may propose something that only survives in winter air.

During the scan: watch limits, not vibes

Power cap time, voltage behavior, and fan ceiling matter more than a single peak MHz headline. If the scan finishes but games die on menu transitions, suspect memory offsets before rewriting the whole VF map.

Validation that catches bursty reality

Stack tests: short sustained load, then a title that compiles shaders aggressively, then your daily rotation. A curve that survives only the first layer is not ready for profile-on-boot.

When to skip automation entirely

Hybrid laptops with opaque EC rules, flaky driver upgrades, or unsupported GPUs often respond faster to tiny manual nudges than to fighting a curve that never matches firmware policy.

After you leave this page

Export a labeled profile, disable auto-load until stable, and read the undervolting article if you plan to combine Scanner output with aggressive negative voltage moves.
