I've been recently undervolting my GPU to try and get the lowest usable watts even at a loss of performance.

The problem I'm having is no matter what I enter into the power curve in MSI afterburner the lowest voltage it will give the GPU is 0.87v. with the graph set it should be sitting at 0.8v but even if I enter 0.7v it sits at 0.87v

Is this a limit set into the graphics card?

Any other tips for trying to reduce wattage for this card?

Thank you
