I'm getting my White 2.16Ghz Macbook tomorrow and I have two questions regarding memory. 1. If one were to install 4GB (2 x 2GB) would the memory take benefit of the dual channel interleaving? 2. Is a 3.3GB (amount recognized by the Merom memory controller) better than a 2GB (2 x 1GB) RAM setup? Thanks for any help. I already purchased the 2GB setup from Apple eitherways. I was just curious for the future. Benchmarks would be superb too.
