Don't know if it the same for phenom. don't know the solution AMD uses to reduce latch-up.
From what AMD told Bongo13, the problem appears to be current related, not substrate differential. This is evident by the fact they said any extended length of time. There is also the situation of it ocurring when clocked up which is heat build up. Look back to to page 2 http://www.xtremesystems.org/forums/...8&postcount=36 where I gave a simplified example of the current curve as the result of voltage increases.
