Would I notice a difference in this memory?

    The Kingston RAM is non ECC so will probably fail a RAM check on start up. I wouldn't risk it.

    Non-ECC RAM will work fine as long as all modules are non-ECC. You cannot mix ECC and non-ECC RAM

    Xeons just let you use ECC RAM if you want to, there is no actual requirement.

    not all non-ECC RAM is compatible. I've tried Mushkin Silverline, which didn't work, and now I use Crucial.

    That would explain the RAM check fails then. :D

    Has anyone compared the speed difference between ECC and Non ECC RAM in their Mac Pro? I assume Non ECC should be quicker.

    3x2GB unbuffered ECC is around 2% slower than 3x2GB unbuffered non-ECC.

    While there are optimum configurations for memory on the Mac Pro, really the best course of action is get as much capacity as you can utilize properly for a budget you feel comfortable with. The speed differences aren't worth worrying about.
