ZOTAC GeForce GT 640 2 GB Review
Value & Conclusion »Temperatures
Temperatures are low, too low given the fan noise of the card. I think it would have been much wiser if ZOTAC went for a better balance between noise and temperature.
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 that we measured. We measure on the pins of a coil or capacitor near the GPU voltage regulator.
| Core Clock | Memory Clock | GPU Voltage (measured) | |
|---|---|---|---|
| Desktop | 324 MHz | 324 MHz | 0.98 V |
| Multi-Monitor | 324 MHz | 324 MHz | 0.98 V |
| Blu-ray Playback | 324 MHz | 324 MHz | 0.98 V |
| 3D Load | 901 MHz | 891 MHz | 1.09 V |
