that url didn't work for me did you mean

ms-help://MS.SQLCC.v9/MS.SQLSVR.v9.en/instsql9/html/09bcf20b-0a40-4131-907f-b61479d5e4d8.htm

that's the h/w reqs for installing and running SQL, NOT the supported features - a subtle difference, but a difference.

I don't know why they would state a MAX memory for installing, but I'll do some digging......
