Depending on what version of XL you have, your system RAM may not mean much:

Some suggestions I copied out of some of Dave Peterson's old posts:

You might try a newer or different version of XL. Some people have had luck
using openoffice to recover XL files (I usually see this suggested when
people cannot open a file due to too many different formats, but still worth
a shot).

http://www.openoffice.org, a 60-104 meg download or a CD

There are also commercial recovery services. I have not and do not know
anyone who has used them, but:

Other than that, I'm out of suggestions. I've never had to deal w/ this
issue myself (and hope that I never will).

Re-post

I am working with an excel file starting from 10 MB, but when I try to create
a table 200 x 10000 and re-calculate all formula, the message about not
enough memory and out of system resource is pop up, as I try to save my work
and check the computer ram [400 MB available] and HD space over [2GB free
space].
When I try to re-open the file, it pops up the message about not enough
memory, and close the file immediately without completely finish the opening
process. The size of file becomes 270MB size. Now I am not able to re-open
this file.
Does anyone have any suggestions on how to solve this problem?
Thank in advance for any suggestions.
Eric
