Hello Tina: The SSDF testing with 64 megs that you refer to above was on a 200MHz processor. The formula for Fritz is 2 x processor speed x seconds per move. At 40/2 which is how the SSDF is testing, Fritz would need just 72 megs. Now, with a 400 MHz processor, that amount of megs should be doubled to 144. This is what is recommended for Fritz according to the formula provided in the manual and on the program. Regards, Mel > >Hi guys >Tina Long
