We couldn’t spend much time to explore the overclocking potential of our GeForce GTX 750 Ti due to time constraints, yet we found out that the card’s GPU and memory could be overclocked by 135 MHz (+13.2%) and 1260 MHz (+23.3%), respectively, without adjusting its voltage or fan speed.
The resulting clock rates were 1155-1220/6660 MHz.
According to our monitoring tools, the GPU frequency would peak up to 1300 MHz in the Boost mode.
When the card was overclocked, its GPU grew 1°C hotter at peak load and its fan's output increased from 49 to 50%. We guess that's very nice overclocking considering that we’ve got an early test sample of the GeForce GTX 750 Ti.
