I notice that the stock voltage is 1.012 which is weird, overvolted from factory? Anyway, I got a problem, that the card randomly throttles to 405 core. For example I might be stressing with furmark and then at some point it goes 405 core and all testing from there on is useless, and I need to restart in order to get it back to normal...
I read something about dual displays causing that, but even though I have a projector hooked up (via audio-video receiver first) besides my screen, the receiver is off and is not visible in nvidia control panel and this throttling stil happens....so I don't think it's related...

The twintech seems reference design, is it safe to try aby of those bioses in your list KET as long as it's 768mb? Is there any of them recommended for a reference card?
Actually 1.025v is the real nvidia stock reference voltage, however manufacturers have choosen to undervolt, and all is well since the gf104 is such a efficient GPU. So your 1.012v is more than most, but its still under the real stock.

And about your throttle issue, are you overclocked, or stock when this occurs?
If your overclocked the driver will throttle the card down when it detects problems, i.e. your overclock is not stable. This is the norm.

If this is happening on stock, you may want to RMA, or I hear nvidia will have forceware 260.xx out today, try that if your still throttling on stock you have problems. FYI the card will throttle on less intensive 3d apps/games to save power, but absolutly not on furmark, unless there is a problem, i.e overclock too high, temps too high, or defective.
