Molpro: conical intersection

[Matthew E. Cremeens]

Hello!
   I want to perform an conical intersection search at the 
CASSCF(10,10)/6-31G* level on a molecule with 7 C's and 6 H's. In Gaussian, 
the job requests a memory allocation of almost 12GB. The system I am 
working with can handle up to 1.9GB but not 12GB.  Would I need so much 
memory with Molpro to run this calculation?  I am willing to sacrifice 
efficiency in the search algorithm so that I can reduce the memory 
requirement.
Thank you very much for your time! Matt
