There are plenty of posts here where people have had memery issues or where Windows wasn't able see all the RAM installed because that box was checked.
At any rate the box is for testing purposes and really doen't need to be checked, especially on a 64-bit OS, unless you want to limit the RAM, or do some testing to see if all the RAM is being used. It could also cause memory issues, especially if you have an intergrated video card. Again, I refer to Binks tutorial I linked to earlier.
Anyway my suggestion is to not check that box but to each his own, and if you feel it works for you well...
Peace
