For anyone who is interested, I have been able to work out a "temporary solution" to my earlier issues with instability.
I'm running a test rig with 2x 1080, 1x 980Ti on W10

Some notes:
-Every additional instance reduces individual GPU speed significantly (14khs/1080/1 instance vs 11khs/1080/3 instances)
-Even one instance of v 0.12 was rather unstable and could not be left unattended for any real amount of time. At 2, miners would start crashing within a few minutes. At three instances (GPUs), crashed within two mines.

So I ran a 90 second loop for three instances, and after observing results poolside, this "technique" has very little effect on hash rate.

Mr Lolliedieb, thank you for your work. This is great stuff!!!!
