Adam Moore3 said:True. I upgraded my rig recently and couldn't unlock it because I grabbed the single-slot version without a power connector—turns out there isn't a modded BIOS for that specific one. 🕺 It was cheap, under $300 at a local discount shop.
Yeah, he probably has the exact same card as mine (mine is a Windforce 4GB, his might be 2GB, but they're basically identical models).
I couldn't find a BIOS to unlock mine either, but since I specifically hunted for a card without a power connector, I don't really care about losing that extra 10% performance.
BTW, undervolting this thing is super easy and actually works.

It holds 1213MHz below 1.0V no problem. It isn't loud, even in Furmark, and you can barely hear the fans while gaming. (For example, it's been running at 100% load for hours now and the fan is still under 1000rpm.)
