Subject: Hash Problem

Author: Joshua Lee

I recently upgraded to 512MB of PC-133, thinking oh Fritz will perform better in
which it does, however i noticed something strange that hopefully someone can
explain. When i had a single 256MB chip Fritz was listing 184MB as the Maximum
with the regular values 32 64 128 etc. Now it seems that the Maximum is 384MB
with the only option given being 286MB , 256MB, 184 128 etc. Well the computer
is an AMD  Athlon 800Mhz, I try different testsets and on various problems
sometimes clearing the hash tables sometimes not but it just dosen't always
solve some of the BS test positions why would it solve 1 position one time and
then not solve the SAME one another time something screams that something is not
right. Luckily i have another computer a 500Mhz PIII and it solves the position
every time the only difference in speed and that there are little or no
tablebases on the pentium, while the athlon has alot . Also some times the
athlon will solve a problem in under 2 minutes while other times it will stick
on a position and will not go to the next depth in fact i have let it sit for
40+ minutes and it didn't change from the depth eval after 3 minutes.

Please someone explain the hash behaviour
