Thanks for posting the article. I read it when it was released, and refreshed the GPU Boost 3.0 now.
What the article says, besides the granular ability in changing the frequency at each voltage mark, it also mentions the dynamic down clocking in comparison to the older cards. From what I've seen Pascal starts lowering the clocks at around 55C. This is not my case fortunately.
Regarding folding. What you are seeing is normal "gaming usage" which usually does not push the card to it's power limit. Also, regarding the voltage, the limit is 1093mV. I suspect you only see 1081mV because of how the default curve is set up. You have the same resulting frequency at both 1081 and at 1093. Boost 3.0 will only go to 1081 because it's the same frequency. If you want more voltage, raise the curve at 1093 by one tick (try Afterburner as it can raise the frequency properly, not in 25Mhz steps as Precision XOC). If the card is not limited in any way (temps, power) you will see 1093mV.
