680 GTX Voltage Adjustments

[TechRookie16]

I currently use a 680 GTX SOC Galaxy. All my settings are set to neutral except GPU Clock Offset which needs to be lowered to -30 MHz. (The overclock addition wasn't getting enough power to sustain this guy at 0)

My question is, 988 mV is the default setting on Precision X for my video card. If the card is being pressed for performance it boosts to max power to supply the card, correct? And if so, what would be the point of raising voltage on the card if the card adjusts to the amount of stress on it during gaming?

Manual volt adjustments are for people who want to manually overclock. If you don't care to do that then you don't need voltage control. I like it on my 7950 because I water cool and so it is useful to be able to push it more than the aircooler can handle. Sometimes it is also useful to be able to test a malfunctioning card to see whether the GPU is not being supplied enough voltage.

didn't NVIDIA lock voltage adjustment in the 6 series?

 

[TechRookie16]

yes but locked it to a certain limit

Sorry, that's a no go unless you get a specific SKU or do a hardware mod.. You can only adjust vdroop which is NOT the same thing, don't confuse the slider in precision X as being real voltage control. It is not voltage control, it only changes vDroop.

You can only adjust voltage with the MSI lightning 680, and you have to manually adjust settings in MSI afterburner and have a proper BIOS to do so. IF you do not have that card, you cannot adjust voltage (unless you hard mod / solder, as mentioned earlier) Also, your card will generally always do 1175mV during 100% gaming load when vsync is turned off. You cannot go above that via software unless you have an MSI lightning.
