[QUOTE="walkerj, post: 718151, member: 9385"] Okay, I just did a check on the results of what putting mismatched pairs or 2x2gig modules into a second generation Macbook that is only "supposed to" address 2 gig, but if you put in 2x2 gig modules in it'll address three gig, and you're better off by having that much more RAM. This is relevant to my interests because I just bought a 4 gig RAM kit for my Macbook intending to do just that. However, it would appear that I would be best served by taking the two 1 gig modules I upgraded my Macbook with to 2 gig by way of 2x1 gig modules, and putting in a 2 gig module in one bank, and one of my 1 gig modules in the other, rendering 3 gig for my Macbook. I can then take my wife's Macbook which still has the 1 gig it came with (by way of 2x512MB modules in their respective banks) and replacing them with the same configuration, i.e. I'll have another 2 gig module from my 4 gig kit, and a spare 1 gig module from my previously upgraded Macbook; both Macbooks are the same 'vintage' of being second generation Core2duo 2.0GHz Macbooks (albeit one white, one black.) It would appear that installing "mismatched" RAM in a Macbook does not result in as much of a performance hit as some might think and the benefits outweigh any possible detriment by virtue of the sheer amount of RAM which benefits Mac OS X quite nicely. So I'll end up with two Macbooks with 3 gig of RAM in each. Sounds like a pretty 'win' situation (that's 'win' as in "this thread is full of 'win'" as opposed to "this thread is full of 'fail' ;)"considering that both will address 3 gig of RAM, there will be no wasted memory, and the best I can do with the hardware I have. I'll find out once I get home (I'm on the road right now posting from a hotel wifi) and install the modules. Should be interesting. Here's hoping for no kernel panics! [/QUOTE]
