Terry, The equation below is used to calculate the minimum hashtables size, and it is in the manual of Fritz5. I believe that it serves for the CM6000. HT(Kb)=2.0*Pfreq(Mgz)*t(S) HT= hashtable size in Kb. Pfreq= clock speed of the processor in Mgz. t= average time avaiable per move in seconds. Examples: 1. Processor with 200Mgz Control time=40/2- Average time 3min=180s HT=2.0*200*180=72000Kb= 72Mb 2. Processor with 200Mgz Control time= Blitz(5min)- Average time=10s(esteemed) HT=2.0*200*10=4000Kb= 4Mb 3. Processor with 400 Mgz Control time= 40/1- Average time=1.5min=90s HT=2.0*400*90=90000Kb= 90Mb The program, in some moves, will spend a bigger time than the average time, then I think that is always good to use a bigger hastable than the calculated for the equation above.
