4Gb in 32bit os showing less than before

[Nick1881]

I'm running Vista Ulitmate 32bit and before I had 4 x 1Gb Crucial and it showed in windows as about 3300MB (roughly), now I have just changed to 2 x 2Gb G.Skill and its showing as 3069MB. Anyone know why this is?

I have to to a re-install really and I'm considering going to 64bit, is it well worth it with 4Gb ram or should I wait til I have 8Gb?

My pc is mainly used to web browsing and playing cod4.

I installed SP1 and now it shows 4Gb in system properties task manager still reports 3069.

I havent changed anything else, system specs are in my sig, very strange how I can now use 300mb less, ah well I may install 64bit this weekend, only trouble is I know I will want 8Gb of ram then lol.

Only 3068mb is addressable. But with SP1 in system properties it now shows installed RAM.

But before it was showing 3300mb in task manager when I had 4 x 1Gb sticks of ram.
