No. Windows will only report 3.25GB. Fat.Clown posted the links with the technical data on this.
Vista with SP1 will SHOW
that you have 4GB but will NOT
be able to use all 4 GB of it in 32 Bit versions. That was a addition to SP1 where it would show that you had 4GB installed.
To know for sure. Start>Run>winver or Right click on Computer>Properties.
That will give you the definite answer if you are running 32 Bit or not.
