Relationship between AGP voltage setting in system bios and core/memory voltage?
As per subject. Is there any relationship? My system bios has a
setting for AGP voltage that goes from 1.5v to 1.65v. What exactly does this setting control? If I increase this number will it increase the voltage at which my video card runs its core and/or memory? |

If I increase this number will it increase the voltage at which my video card runs its core and/or memory? On an AGP motherboard, there is an AGP bus that runs between the Northbridge and the video card. The bus signals need a source of power. There are occasionally video cards, that are not happy with just 1.5V, and applying a little boost reduces the error rate to zero. To be honest with you, for the number of people who have played with that setting, I cannot remember too many cases where they actually got an observable benefit. That bus voltage is independent of the GPU core voltage and the graphics memory chip voltage. The AGP bus voltage should only be used between the Northbridge and the GPU, on the AGP bus signals.
