I think it will be easy for everyone to follow you with it opened in MBT.

This my personal BIOS for my SC ACX2.0 GTX 970 with an ASIC of 70%. On stock, it only boosted to 1.200V
After many tests I concluded that the card hits its limit at 1.212V, therefore I don't use the 1.212V.
It uses my tested 1481.0 at 1.200V where it's stable. Power limit is also slightly increased to 196W default and 206W max. Those cards are IMHO not designed to get pushed higher, not with that junk of a cooler. 196W is a good value to keep temps still reasonable. I haven't seen the card throttling in games (this was the main reason I modded in the first place)..:EXCEPT firestrike demo and some special cases which I think is where most cards throttle.
* Be also aware this is for the standard SC ACX2.0 cards which have a crappy voltage controller which does not go higher than 1.212V and which also doesn't allow setting voltage externally.
A SSC+ etc. uses entirely different components, it also has 1x6pin + 1x8pin...so use my BIOS only if you have a normal SC ACX2.0 card and think that it would do 1480..and you want it stable. (Obviously, SOME cards might get higher....but for me I found 1480 the best, 1510 etc. might black screen me out after an hour or so Heaven Benchmark, even at 1.212V)
Edit: The fact that I dont use the maximum possible Voltage of 1.212V in my bios has another advantage: It never reaches the voltage limit!
