Settings for voltage control on newertech 2ghz accelarator?

[Akamadman203]

I keep getting an overdraw in voltage on my accelarator and don't know what the dipswitch settings are. Just a heads up for those who mention it I do know there is overclocking dipswitch settings but I'm talking about the settings on the center of the accelarator. Any assistance to this question is greatly appreciated.

Update to this my GPU was overheating and causing crashes I still do want to know how to adjust the voltage for other reasons but I now know my current issue
