Success!!
After fiddling around, I was able to get +200 core and +100 or so on the memory, giving me a greater than 10% boost on this Vanilla Zotac 970. Unfortunately, until there's a BIOS update, I'll have to deal with the voltage fluctuations under load, but boost maintains relatively the same speed. Telling MSI Afterburner to prioritize temp limit over power limit seems to have helped.
I found that increasing my memory speed much more led to power limiting and causing the boost to lower. So that is the happy medium. As I close in on 1500MHz Core I did notice some artifacting in Unigine Heaven, so I dialed it back 50MHz. I'm hovering around 1460MHz and couldn't be happier. Max load temp of 65C!
Seems good with the ol' i7 920.
