Voltage keeps lowering in AB - 680 Lightning

Got my 680 Lightning today, running an unlocked BIOS on Afterburner 2.2.3. However, every time I launch AB it lowers the mV of OC. So if I set it at +74mV, for example, the next time it launches it's at +67mV, then +61mV and so on.

Any ideas?
 
You will have missed it due to this being a recent purchase, but in the 2.2.3 release notes it explains that you can't apply an overvoltage and still use the 'apply overclock at system startup' option.

this is because the voltage adjustment has had to be made in a convoluted way. it polls the voltage settings at startup (or something )and adds voltage to that value by a fixed amount (the driver+firmware adjusts the voltage dynamically).

You need to save you overclock as a profile and then load it each time you want to apply it.

this is why if you make a minor change to one of the clock speeds and click apply the voltage offset will drop from what it was set to. (I believe by the diffrrencr between idle and 3d clocks)
