you mention you have 6GB of RAM. I assume that you know a 64-bit
Operating System (besides the applications being 64-bit) is required to
break the 3GB RAM limit.

* If you bought the machine with 6GB already equipped then they _must_
have installed the 64-bit version of sVista [*]. Then follow Markus'

* If you did a RAM upgrade by yourself (e.g. from 2GB to 6GB) then did
you check that you have a 64-bit sVista?


[*] svista means in greek "erase them" ;-p
