Here is an interesting experiment involving Hash Table settings.
This was run on a single processor 350MHz Pent II 384 SDRAM with Nalimov 4 disc
Endgame Turbo plus additional downloaded 5 piece endgames and Permanent Brain
turned off.
For my computer's speed the proper HASH TABLE settings for game 5/12 should be
16 MB. I have found that 32MB has always worked well, however.
As an experiment, since I believe Fritz 7 performs better than Deep-Fritz 7 when
using a single processor (even though Chessbase boasts otherwise, stating that
DF7 is stronger even when usning a single processor).
I raised the Hash Table settings for Fritz 7 to 192 MB as opposed to
Deep-Fritz 7 set at 32 MB Hash.
Surely, 192 should be much too high for such a time control with my processor
speed. Well, Fritz 7 still beat out Deep-Fritz 7 by 5.0-3.0

1 Fritz 7 110½011½ 5.0/8
2 Deep Fritz 7 001½100½ 3.0/8
Can anyone please explain this please? Aren't proper Hash Settings supposed to
make a difference in the playing strength of an engine? Surely, Fritz 7 should
have lost with such a ridiculously high Hash Table Setting, should it?
Or, is it just a total waste of time to run a engine tournament on one PC?
I have found out that Fritz 7 has been continually out performing DF7 in
engine tournaments. BUT I have also been getting better results with Fritz 7
than DF7 on ICC vs Human competition on my Computer account.
Here the games for any who are interested:
