In anticipation for OS X Lion, and RAM price dropping lately, I kind of want to upgrade the RAM in my Unibody Aluminum MacBook (not sure what's the "Early/Late Year XXXX" name) 5,1.

My understanding is that due to a firmware upgrade, my macbook is capable of utilizing 8GB of RAM. I am currently at 4GB, so the logical upgrade is to get to 8GB mark.

I notice there are PC3-8500 and PC3-10600 modules. According to System Profiler, I am currently using two PC3-8500 (1067 MHz) modules. Does it matter which one (PC3-8500 vs PC3-10600) I get?

I'm wondering, because on top of hardware support, I see one set of PC3-10600 with 9-9-9-24, while the other set of PC3-8500 is with 7-7-7-20, and my understanding is that the smaller those numbers are, the better they are. And I find the contradicting numbers very confusing.

Can someone please shed some light as to which one I should get for my upgrade? TIA!

I would love to know this as well. I have the aluminum MB, with 2ghz c2d and running 4GB, will it run 8? And so it stable? It's also 5,1.

It's very stable. Well worth the upgrade.
