Anyone already tried this? How did you get on?? :-) \/ \/ \/
Just noticed with 'MSI Afterburner' 4.3, Beta 14 you can now actually lock your voltage and core frequency at any point along your curve to test for stability at each voltage point to build your overclock.
Officially they only support FE and MSI but I just tried it on my EVGA Classified 1080 and its working 100%
Here is a quote from the page:
"You may press after selecting any point on the curve with mouse cursor to disable GPU dynamic voltage/frequency adjustment and lock the voltage and core clock frequency to a state defined by the target point. This feature allows you to test graphics card stability independently for each voltage/frequency point of the curve using real 3D applications or any stress test of your choice. In addition to stability testing usage scenario, MSI Afterburner allows you to save a curve with locked point setting to a profile, so you may easily switch between dynamic voltage/frequency management and fixed voltage/frequency settings in realtime (e.g. to achieve the maximum performance during benchmarking). Please take a note that fixed voltage and frequency settings do not allow you to disable power and thermal throttling"

There is no button on MSI Afterburner yet to access the voltage curve you have to press CNTRL-F to get the window up.
This should let us squeeze every last drip of performance out of our cards by fine tuning them to the absolute limit. :-)
