I am considering buying the new Macbook Pro Core 2 Duo that was announced a couple of days ago. One of the configurable options is to load it up with max DDR2 RAM of 3 GIG in 1x2Gig and 1x1Gig arrangement. I heard about the dual channel memory benefit of accessing in full 128 bit mode when the RAM are installed in pairs. So my question is if I upgrade to the above configuration, would that wipe out the benefit of 128 bit access? Thanks very much.
