So this latest BIOS you tried got you 2-3 more frames in Valley? What did it bring your clocks up from/to?
Yeah we may be hitting the wall soon, as far as how high the voltage/power limit can go with a modded BIOS, but I don't think many people are going to complain now (I mean...~1200mhz on air. That's almost a 40% OC over the stock Boost). Same thing happened with the 680 Lightning. As soon as people got the card and flashed to the unlocked BIOS, they were content and mostly forgot about how locked down the card was when it got to them. Since this seems to be working well, I wouldn't be surprised if Nvidia didn't even post a response at all to the throttling. People content with the card as-is will continue being content, and those 'in-the-know' will just flash their cards and be happy that way. Everyone is more or less satisfied one way or the other and Nvidia just drops it altogether. I would like to see what kind of answer they come up with though, or at least an explanation. But I doubt they will at all at this point.
Just a question also, thought of it after mentioning the 680 Lightning...how is it that the Titan Lightning rumor was believed by so many, but MSI didn't even get any to begin with? How would MSI bin for Lightning version chips when they never got any in the first place? Did they not get any because of the whole 680 Lightning voltage-control thing (in the beginning)?
