I am also running Hiarcs 7.32 with max hash at all time controls. It works fine and does not hurt Hiarcs 7.32 at all and even helps it some I now believe. Your results pretty much mirror mine, I also show Hiarcs 7.32 better then Fritz by about 18 points in head to head play, but with fewer games only about 200. When I calculate all game played by Hiarcs at all time controls against all other programs. Hiarcs 7.32 elo advantage is almost 50 points better then Fritz, do you show the same.
