    Hi all: I just ordered a new 17" (i7, 8GB RAM, 500GB @ 7200 RPM, etc.). Should be quite an upgrade from m CD MacBook (2 GHZ CD, 2GB RAM MAX).

    One question: From the wikipedia article on the Nehalem microarchitecture, it seems that the Core i7 connects to two slots of DDR3-1066 RAM.

    Now, that means that the current max RAM in these machines is 8GB, as 4GB SO-DIMMS are the largest available.

    But: I know that 6,8,12, and above SO-DIMMs will be coming very soon.

    So, once you can PHYSICALLY fit more memory in those two DDR3-1066 RAM slots, will the computer be able to undersand/do something useful with it? or is there some other component of Nehalem that prevents it from addressing more than 4GB of RAM?
