Ok. Plus, indeed, reports that they worked were based on Core i5 or i7 machines and not on the Core 2 Duo that I have. >> That does not seem to be the case.

What latency are they, and what voltage? I wish I could tell from the package. They are Corsair "Mac Memory" chips and the only technical information I seem to find is: 2x204-pin SODIMM DDR3 1333mhz 9-9-9-24 Searching on the web seems to give a 1.35v voltage but I can't seem to find the latency.
