I'm not sure which "cold boot" problem is being mentioned when it states it's been fixed. Not mine and that's for sure.
When I first got my 2 GTX680 FTW+ everything was fine except one card would have a whistling noise under load. Then as time went on the whistling card would drop to 324MHz more and more after a cold boot. I would need to run the system for around a half to a full hour with or with out a load on the cards till the one would stop dropping it's clocks down.
With these new drivers it's better, much better actually. But it's not gone by any means.
Things I have noticed are:
1. The offending card does not boost and/or overclock as well as the other.
2. When using vsync on, and EVGA OC scanner to test the cards, they run at the default core of 1084MHz but the offending card needs more voltage 1.112 compared to the 1.087 the other one needs.
3. When the card down clocks in the test I outlined in 2 it doesn't ramp back up to the default clock but instead up to it's highest boost core clock.
4. When no longer down clocking, while running the test in 2, I've noticed that both cards will jump to their max boost even with the FPS locked at 60. It's very rare but it does happen.
While I first thought the "bad" card might have a power phase problem I'm now wondering if might also be a firmware and driver problem in regards to power management and the adaptive clocks. While I know some have gone the RMA route with this problem, I'm going to give it a bit longer to see it a driver/firmware update doesn't fix it.
Fingers crossed.
Update:
Well I spoke to soon. Cold boot problem is the same as before.
