Russ, I have multiple CF 7 servers using 1280 - but remember that your other memory switches come into play as well (permsize, maxpermsize, newsize etc). The aggregate heap can't go over a certain amount of contiguous memory.

There is a limit, but hopefully Adobe will come up with 64bit support soon. In the meantime, I'm having trouble setting the setting -Xmx 1280. CF7 doesn't like that. It works well with 1024. Is there a smaller limit for 1.4 JVM?
