I installed 4GB RAM (the correct RAM) and I'm running 10.5.2

When I click about this mac, it says I have 4GB RAM installed so I know everything went smooth when I installed the modules.

BUT, when I go to my dashboard and look at iStat Pro, it says I usually have about 2GB free. Is this normal ? I'm not really running much (2 programs) right now and it says...

MEMORY
Wired - 668MB
Active - 1.20GB
Inactive - 477MB
Free - 1.68GB

It seems to me that I should have well over 1.68GB RAM available.

Does anyone know what's going on here ?

Thanks in advance -

In general, OS X will cache more information as RAM increases. So if you have been opening and closing applications for example, just because you are only running two right now does not mean info for others is not cached. You will likely find that opening programs is faster after they've been opened once before.
 
true true, I guess when I start up my macbook it does have more RAM than after I close out of apps. And yeah the programs do open up quicker.

Thanks -
