In Shredder you can excatly specify the amount in hash Shredder shoul duse in MB. I also display the free memory in that dialogue, but for reasons unknown to me in Win 9x this value looks random sometimes. With NT it's fine. >In a seconds step decide on how much hash to use depending on time control, >since clearing or "making old" big hash tables between moves may hurt in very >fast games. In Shredder5 you can make the hash as big as possible without problems as I never clear of mark entries in the hash after each search. Stefan
