I mean I used to run SVD with my implementation storing only three
arrays (user, item, rating), that I was able to fit in 3GB memory. I
guess GenericDataModel takes up quite a lot of memory, because the data
is indexed by users and by items, which is not necessary for SVD

Memory requirements may be much higher for this algorithm as it builds
large intermediate data structures to compute the SVD. Yes I think the
simple data fits in 3GB or so. Sounds like you have solved your
problem by supplying more memory.
