IE 2mb is not possible for hashp, but 2.5 mb is. or 5 or 10, etc... it is the number of entries that must be a integral power of 2. hash entries are 16 bytes which works out as you saw, but hashp has 20 byte entries which breaks your approach. In general, there is no real need for hashp to be 1/4 the size of hash. I use hash=24M and hashp=5M on ICC all the time. For longer games I generally use hash=96M and hashp=10M, but I am not sure that the bigger hashp makes much difference. Watch the pawn hash statistic. If it is 99%, making hashp bigger will *not make it any faster... > >Any tips appreciated. > >Yrs, >AceyMan
