My O/S is Windows XP Pro and I have 2Gb ram, I understand that if I install 4Gb ram Windows will only recognise less that 3 Gb. As I`m thinking of going to Windows 7 if it seems to work OK. I could use $Gb ram. Point is, is it worth installing the extra 2Gb ram now or wait until Windows 7 installed.
If you installed 4 Gig of ram, xp will or may only see from 2.75 to 3.5 gig of ram, but xp will use all of the 4 gig. I personally only have 3 gig of crucial ram and it works very well & with 512 Graphics.
