    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?

    Four is like dual channel but slightly faster.

    EDIT:

    Umbongo is correct...

    It appears MPG has some facts...

    This confirms that running 4 equal DIMM's offers between tri and dual channel performance. Which is also what AnandTech indicated:

    Real world performance difference:
