I killed a Q3QR A0 hexa after ~10 minutes on SS (-30C), and I was only running Cinebench at ~1,65V Vcore. So it stands to reason that the same CPU would have died running WCG @ 1,55V Vcore on water.

As I said, I would not recommend going over 1,4/1,35V Vcore/VTT for long term crunching unless you are prepared to face the consequences.
If vCore has killed your A0, does it means that VVT didn't kill it?

I'm not recommending to use too much VVT, just suggesting that Intel's recommendation on VVT-increase for 980x, plus these chips probably has a better and more resilient Uncore than 980x, plus i7 45nm ability to take 1.5v VVT for 24/7, all togteher suggests that these chips may be able to take a good deal of VVT for 24/7. But nobody knows how much torture they can take yet, and it is a good idea to be careful.
