I have the HD 7970 reference card, the first revision bought on January 2012.
My ASIC Quality is 87,5%, VID 1,05V.

My sweetspot is 1200MHz at 1,15V

This is the orginal BIOS:

Still just working on tweaks in my spare time. If others would submit there bios i would edit them but in my spare time. As its a bit time consuming. I don't know how they mine since im not a miner but suttering has went down in crossfire, also seems better in benchmarks. For my own cards that is, what is posted above is Lards improvements, at the same clocks just edited bios ram timings and other bios tweaks.

pick one and send me the bios and i will adjust your timings a bit more aggressive but it will depend on your card weather or not it can run it without freezing. I will drop the higher frequency a slot lower so 1700mhz in the 1500mhz slot since thats what you are running.
