"Honestly speaking, I think most end users don't even realize how maxwell gpus are voltage capped at ambient type cooling. I can tell by many of the comments at OC.net, elsewhere, and also here in these card XOC bios threads. Especially compared to kepler. KP 780ti scaled great on voltage with air/water temps. Basically, more voltage = more clocks no matter what temperature.
With 980 and later gpus including titanX, the scaling on air/water has all but almost gone. I would say about 95% of all maxwell 980,titan-X, and 980ti gpus NO MATTER what vga brand pcb it is on, DO NOT SCALE with more voltage than 1.25v-1.275v at temps warmer than 25c or so. There is no magical bios that can effectively remove this.

This is exactly why almost every moderate-good asic titanX, 980, and yes 980ti clock around 1550mhz MAX AVERAGE at say 45-60C loading temps.
If you put 0c and colder on the card, you will see MUCH different behavior than what you see on air (green garbage all over screen when raising volts over 1.23-1.25vv or so)
Cards with very good ASIC value (75% and up) will tend to have the most "overclocking", but just like about every other maxwell gpu, they cannot overvolt past 1.23v-1.25v.
So highest asic cards like 80% +are almost always going to be the ones that can 1600+ on air/water, and again they do it pretty much WITHOUT overvolting over 1.23v-1.25v. Maxwell gpus with lower asic value like 65% will not be so great at air/water because these low asic gpus need voltage to scale compared to match the overclock of the high asic gpus( USING SAME USABLE VOLTAGE 1.23-1.25v)

The bios's I posted basically allow you to set a higher voltage on air/water. Some gpus can scale more, some cant, some actually will NEED more voltage than was previously needed to run same frequency. All different.
