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.
