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 performed the measurement on the pins of a coil or a capacitor near the GPU voltage regulator.
Normal BIOS:
| Core Clock | Memory Clock | GPU Voltage (measured) | |
|---|---|---|---|
| Desktop | 300 MHz | 150 MHz | 0.95 V |
| Multi-Monitor | 500 MHz | 1250 MHz | 0.95 V |
| Blu-ray Playback | 501 MHz | 1250 MHz | 0.96 V |
| 3D Load | 850 MHz | 1250 MHz | 0.98 V |
| Core Clock | Memory Clock | GPU Voltage (measured) | |
|---|---|---|---|
| Desktop | 300 MHz | 150 MHz | 0.96 V |
| Multi-Monitor | 500 MHz | 1250 MHz | 0.96 V |
| Blu-ray Playback | 501 MHz | 1250 MHz | 0.95 V |
| 3D Load | 950 MHz | 1250 MHz | 0.97 V |
