Subject: your comments on hash

i have seen the effects of changing hash values in a benchtest. i saw where
stefan used maybe three sticks of 256 to get 768 megs of ram for shredder, when
he won the world. i also see where sarah is using 48 megs hash with a 900
t-bird. with these large amounts of ram, what are some of these guys setting
their hash values at.   is there some sort of standard, for example, say for
this mhz at this time control, with this amount of nodes being searched, then we
should use this hash setting. do you think with the new processors that will
search 1000-1500 kns, that these will take more hash then is usually
recommended. how should i look at this setting for optimum performance? maybe if
i play a 3/0,  32 megs would be enough with 800 kns. but on long time controls,
30 minute game or longer, it almost seems that you cant have too much ram. is
there a point where increasing hash does not decrease kns? but i have read where
alot of you guys dont use windows. i use 98se.  also if some of you are using
windows 98se, could you tell me how you are managing your virtual memory.

thanks
