    Hello!

    I would like to update my mid 2009 (last version before unibody) MacBook with two 800 MHz DDR2 SoDIMM modules to 4 GB total. I see offers of noname modules but they are all CL6.
    Although one of the seller claims they work in the MacBook, I had problems in various desktops with CL6 DDR2 memory. It seems CL6 does not really work for DDR-2.

    I'm much more suspicious of no-name RAM than I am of the advertised timings.

    I bought the 1 GB module for my iBook G4 from there and it worked. (Labeled Hynix.) Later bought 2 GB DDR-2 modules (labeled Kingston) for an IBM Intellistation and they don't work. Seems the IBM don't support CL6, it works only up to CL5.
    The ones I intend to buy for the Macbook seem to be Kingston too.

    So again my question, will the mid 2009 Macbook work with CL6 modules if the modules are indeed in their specified parameters or can the MB not handle them?

    edit: and run it at 800 MHz FSB.
