Maybe they won't last 10 years.... Maybe only 7.... The useful lifetime of these boards is measured in months at this point...
OC FTW !
My thoughts exactly. I'm hoping for 12 months, but I am most definitely an optimist. If there was a way to OC, I'd be all over that.

There is, by replacing the regulator. Atleast one person so far has done this and has reported about 10% gains from it. It does void the warranty and does require a skilled professional to do, but is possible.
link? I was under the impression that if a board has <16 working chips, it may be possible to overclock the others using the additional headroom provided by not running a chip (ie: 2/16 chips dont work -> 12.5% more power available to working chips. (am i correct on this, can anyone confirm?)
Only if you remove the chip and bridge its spi chain. If the chip is powered, it's consuming at least idle current, and if it's been configured, it's consuming full hashing current, regardless of how much work it's doing.
Also, the chips aren't going to automatically consume more current and run faster just cause current is available. You'd need to turn up Vdd (also an advanced maneuver

)
