Will there be a noticable speed decrease if mixing memory size on the nMP?

    If you have 4X4 and add a 16gb 1 at a time as budget permits will the machine take a noticeable hit in speed?

    Depends what you use it for. Single channel memory performance isn't the worst and you still get a perfectly usable system. I'd aim to get two 16GB though and sell your old memory if you really need 32GB.

    Are you getting page outs with 16GB?
