Does the MSI Afterburner "Core Voltage (%)" Slider Do Anything For NVIDIA 3000 Series GPUs?

[CyberCT]

In MSI Afterburner (v 4.6.4), voltage control is unlocked and the top item in the main screen is ""Core Voltage (%)" with a min of 0 and a max of 100. IDK if this is supposed to be an additional 0.1v to the core, an additional 100% voltage (which would make no sense), or what. I searched the web and actually can't find much on it for the 3000 series, other than "it doesn't do much" which doesn't tell me anything.

Does anyone here even know how it affects the Nvidia 3000 series, if at all?

It could be the driver overriding the software voltage tweaking.

Core Voltage hasn't done anything for the 20 or 30 series. The limit is still 1.196v unless you have a Galax HOF or EVGA Kingpin card.

I think some cards 0% is 1.16 and 100% brings that up to 1.196v.

OK, so whether I leave it alone at a blank (assuming 0) or put +100, it'll change nothing to help and overclock / undervolt is what you're saying.
Did you read this somewhere, or is this from your own trial and error?

Hmm. Its a mix of the reading section in the XOC scene and some testing of ny own to confirm some stuff.
