MBP RAM Question

You have the same Mac as I. You could put 2 x 2gb sticks in there, but the Mac would only use 3.1 gb or 3.2gb... something like that. Personally, I'm going to put a 2gb stick in mine to bring it up to 3gb, upgrade the hard drive late next year and probably sell it in 2010.

 

I believe that maximum it can address is actually 3.3GB (yes, a whole 100MB extra) but I saw another thread on MR where someone who did just that, experienced issues when applications tried to grab more than 3.3GB, leading to stability problems.

I'd recommend just upgrading to 3GB, the performance boost you'll see will be better than the boost you'd see with an extra 300MB RAM that are both the same size (I believe the boost was something like 6-7%). Marginal.

I run a MB C2D with 2.5GB RAM (upgraded from the stock 2 x 512) and it runs sweet.
