Hello,
ive just upgraded my pc with 4gb kingston memory but in windows vista i can only see 3gb appearing what is the matter? i dont think that one of the ram isnt good as its two modules of 2gb each and if one wasnt good then it would show only 2gb and not 3gb..
please help me in this issue?

In theory windows vista can accept 4gigs of memory but in practice when its done only 3gigs can be seen and that doesn't mean that it isn't using the the 4gigs it is and nothing to worry about.

as far as i understand it, 4 is the TOTAL limit for 32-bit operating systems.

this 4 includes your graphics memory (yes, even dedicated 'on card' memory) and a bit for the bios.

4 gig ram + 1 gig fx card ~= 3 gig of your 4 gig ram can be 'seen' by windows. if you have sp1 installed it will even report 4 gig, it knows it's there, it just can't handle it.

hope that helps!
