Crafty's main hash table (transposition/refutation table) must be a perfect
power of 2, times 3/4.  IE 48M will work, or 96M, etc.  But not 64M.  It rounds
down to the next lowest correct value.

I have no idea what chessbase does with that however, but if you use 48M it
should work fine.  hashp is a different matter (pawn hashing).

I personally recommend everyone use the "adaptive" hash settings that will
dynamically vary the hash size based on the time control of the game being
played.
