You should post your model if possible. Since you are new and model is large you will probably have to use a file sharing site like drop box.
How are you determining SU is out of memory.?
For programs the windows memory manager controls the allocation to programs. If you are getting a warning message make screen shot and post here.

Have you used 32 or 64 bit SketchUp?
