I don't know, I haven't tested them yet. Basically I think that they test some in the factory and any that give an average voltage of 1.15 or more are considered "high voltage" The new design might be on the standard cells soon (now?) too. 1.15 doesn't sound like much, but considering they are not zapped and it is their first run, it's not bad, although lots of the standard cells are also +1.15 on their first run.
