That is not a lot of ram and your main problem. You will be much happier with
a 64bit OS (which typically means Linux or OS X, but can be Windows if you
want to become a REvo customer) and more ram -- which you need to share among
all your cores.

Martin Morgan made this an explicit point in our 'parallel R' survey paper:
available ram is likely to be a binding constraint.
