What interface are you using?  Rybka's, or Fritz?  Yes, Rybka 3 plays stronger than 2450.  :)

i am using rybka3 on arena 2.01

but i am sure i have seen in rybka that max strength is 2400 ..how to increase it ? it was my 4th question

 I don't know how arena annotates games. But the best way to analyze games are looking at every move with the engine by yourself, diving into variations when necessary.

About second per move. It doesn't work that way. The relevant information is the depth that the engine goes into, and it depends on the position of course. However, just to give you an idea, Rybka 3 around depth 18 would probably play around 3000 if it'd enter human tournaments. That's just a guess of course. 

You don't have to set the strength, you are probably trying to set the handicap which runs from 700 to 2400 for me. I don't know what interface you use, but if you just turn on Infinite Analysis you should get the full 3200-elo strength

Ok ..if arena dont cant give me annotated chess review ..which interface can do it ...plz let me know
