So that makes it a bonehead decision not to honor the warranty from their end if the user actually uses it for it's intended purpose, and this ability was heavily marketed by AMD itself(calling it the awsum mode), in all the release reviews when the card was launched a few weeks ago...It's a stupid decision on their part to be quite honest.
There's no sugar coating this one unfortunately.
I think the issue is based on power consumption. By flipping the BIOS switch, you significantly increase the power draw to the card. There are PSU's out there that would not be able to handle the load, thus creating an unstable experience. Without that switch being flipped, the chances of such a thing happening are completely determined by the PSU itself. In that case, the only solution is to get a better PSU.
They're probably voiding the warranty because they don't want people simply returning the card because their PSU isn't up to snuff and take that mistake for their card being defective and returning it. It's all about maximizing profits.
