Inteface: Rybka/Fritz 12.

Max Hashtable 7615 MB

My computer x64: i7 CPU 930 @ 2,80 GHz 12 GB RAM.

I find out of your description, for my computer:

HT [KB] = 5600 x t [s] (2,80GHz x 2 = 5,60GHz = 5600 Mz)

Game 7 min + 30 sek = 420 sek + (90 moves) 2700 sek:

(expected move: 90 minus BOOK 15 moves = 75 moves) = 420 sek + 2700 sek = 3120 sek.

Hashfacktor: 3120 / 75 = 41,6

Hashtable: HT [KB] = 5600 x 41,6 = 232960 / 1000 = 232,96 Hash.

Game 5 min + 5 sek = 300 sek + (70 moves) 350 sek:

(expected move: 70 minus BOOK 15 moves = 55 moves) = 300 sek + 350 sek = 650 sek

Hashfacktor: 650 / 55 = 11,8

Hashtable: HT [KB] = 5600 x 11,8 = 66080 / 1000 = 66,0 Hash.

Game 3 min + 5 sek = 180 sek + (50 moves) 250 sek:

(expected move: 50 minus BOOK 15 moves = 35 moves) = 180 sek + 250 sek = 430 sek

Hashfacktor: 430sek / 35 moves = 12,2

Hashtable: HT [KB] = 5600 x 12,2 = 68320 / 1000 = 68,3 Hash.

This setting work wery well at Kurnik.

One question: What about my RAM?

And what about long analyzes for one move?
