Now that the new Mac Pros are out, has anyone been able to determine how the channels relate to the memory configuration? Right now I have three 2 GB sticks; I was thinking of tossing in another 2 GB stick for a total of 8 GB, but I'd rather not if it would revert it back to single channel. Dual is fine. Triple isn't all that necessary in real-world apps. Would four 2 GB sticks = dual channel?
