When app starts it displays estimated RAM for DPs based on -range and -dp options, multiply it by -max option to get required RAM (roughly).
Or download latest sources and compile them, I added max RAM size calculation.

Code:

...RCKangaroo.exe" -dp 16 -range 75 -start 4000000000000000000 -tames rckang75a.dat -max 3

I must not have understood correctly but in this case the ram displayed is indeed 0.315GB and -max 3 it should take 900 MB or even 1 GB but it took 352 MB exactly 352055KB, why? Huh
