From the technical document from Adobe at:

" Photoshop can only use the first 2 GB of RAM on the computer. This
limit is based on hardware and operating system limitations. The
operating system uses some of this RAM, so the Photoshop Memory
Usage preference displays only a maximum of 1.6 or 1.7 GB of total
available RAM.
If you have 4 GB or more of RAM, set the Maximum Used By Photoshop
in the Memory Usage section of the Memory & Image Cache preferences
to 70%. This amount ensures that Photoshop uses as much of the first
2 GB of RAM as possible, while reserving enough RAM for other
applications. "
That techdoc specifically refers to Photoshop CS. It doesn't apply to
CS2. (CS2 can address 3 GB directly, and uses the OS swapfile as a
cache for its own scratch file when additional RAM is available.)
