Temperatures
I would say temperatures are reasonable for a passive card. 83°C is the temperature limit NVIDIA's driver sets before it will reduce the clock boost to, possibly, stock, but never below.
This mechanism ensures that the GPU doesn't overheat in even poorly ventilated cases, yet the driver will not completely cripple the card's performance until the 95°C mark, which the card should never reach if you use it normally.
Clock Profiles
Modern graphics cards have several clock profiles that are selected to balance power draw and performance requirements.
The following table lists the clock settings for important performance scenarios and the GPU voltage we measured. We performed the measurement on the pins of a coil or a capacitor near the GPU voltage regulator.
| GPU Clock | Memory Clock | GPU Voltage (measured) |
---|
Desktop | 135 MHz | 203 MHz | 0.93 V |
---|
Multi-Monitor | 135 MHz | 203 MHz | 0.93 V |
---|
Blu-ray Playback | 135 MHz | 203 MHz | 0.93 V |
---|
3D Load | 1020 - 1163 MHz | 1350 MHz | 1.012 - 1.156 V |

The card uses NVIDIA's dynamic overclocking mechanism, GPU Boost 2.0. It will dynamically adjust clock and voltage based on render load, temperature, and other factors.
For the graph below, we recorded all GPU clock and GPU voltage combinations of our 1920x1080 resolution benchmarking suite. The plotted points are transparent, which allows them to add up to indicate more often used values. A light color means the clock/voltage combination is rarely used and a dark color means it's active a lot.
