Overclocking a GPU pushes its core clock beyond factory specifications to extract extra performance. However, each additional megahertz generates heat, and without sufficient cooling the silicon can become unstable, leading to crashes or permanent damage.
The junction temperature – the hottest point on the GPU die – is the critical metric for stability. As the temperature approaches the device’s maximum rated junction temperature, the margin for safe overclocking shrinks dramatically.
This calculator estimates how much additional clock speed you can safely apply based on the difference between your current junction temperature and a target maximum temperature, using a temperature‑to‑frequency coefficient.
