    4gb PC2-6400 sodimm does not seem to work with a 1gb pc2-5300 stick
    left
    in the macbook pro3,1

    I assumed since 4+2 combo works 4+1 (the latter being the original
    sodimm) should work fine.
    does not seem to

    any thoughts?

    Does that 4 GB module work if you take the 1 GB module out?

    If not, then it is incompatible with the MacBook Pro for some reason (I
    would expect it to work just at a lower speed than rated, but I haven't
    tried one myself and generally go for the correct speed rating where
    possible).

    If it works by itself, then perhaps the mixed speeds are causing the
    issue.

    Does not work on its own and,sadly, there is no pc laptop accepting
    pc2-5300/6400
    to victimize
