    please, you don't need to ask why I would want to do it. I understand that many people should not want to do this. with this caveat, is there any software available today that allows increasing the speed of the Nehalem processor at run-time (i.e., not at EFI BIOS boot time)? I believe the answer is no.

    [zdnet had this for the previous generation Mac Pro, but not this one, I believe.]

    It does not work on Nehalem architecture. ZDNet, IIRC, clocks up the FSB somehow, and Nehalem doesn't have an FSB to clock up (uses QPI instead). Anything to OC the Nehalem systems would probably have to rely on BCLK and uncore values.
