It's been a while since posting to the forums so I thought I'd add to the fray of crazy, misinformed posts here in the MBP Forum (strangely reminiscent of the iPhone Forum) with a question that's probably already been answered.:)

I just installed 10.6 the other day and immediately upgraded to 10.6.1 and now for some reason the Activity Monitor says the OS is only using 3.75 gigs of RAM when in Leopard it stated the correct four. I'm not really mad, I mean it never uses everything, there's always at least one gig of "Free" RAM, but hey, I paid for it, it should be utilized IMO. Is this a serious problem or should I just go blog about it until I feel better? Thanks in advance, happy trails.

Got a 9400M I presume?

Leopard would report 4GB of RAM despite the fact that 256MB of it was always in use by the graphics processor. Snow Leopard shows the actual amount of RAM you have to work with.

No kidding? That's neat. I have both chips actually, I'm currently using the 9400. I knew that RAM was used but I hadn't made the connection. Thanks for the help.:)
