I don't know VMD but exporters are sometimes not optimal. For instance, it 
could be that every primitive gets its own texture statement. With hundreds 
of thousands of atoms, this alone could waste a lot of RAM. Having the 
primitives grouped in several union{} and the textures applied to each group 
would reduce the memory use.

For instance, the scene below uses 688 Mb when the texture is attached to 
each sphere and 208 Mb when the texture is applied to the group.

union{
    #declare i=0;
        #while (i<1000000)
        sphere{x*i*2,1
//            texture{pigment{rgb x}}
        }
        #declare i=i+1;
    #end
    texture{pigment{rgb x}}
}
