    I wouldn't play with such things. A minor mistake could lead into a huge problem. Better safe than sorry is what the old proverb says. ;)

    Can you run reggie_se -l (this is lower case "L") to list all processor MSR registers?

    This should be pretty safe because you cannot exceed neither CPU speed nor its voltage.

    Could you please also run
    Code:
    sysctl -a | grep cpu
    to get exact CPU details?

    aren't you thinking the wrong way? crashes usually come when you have to little volt. if you have too much volt, your cpu will overheat. i'm sure your mac pro is not doing that since they run very cool.
