    I know there have been various threads about this issue, but I can't seem to get an answer. From what i've read, 8GB will work fine in a late 2008 macbook with ML. My question is, does it have to be 1067 Mhz, and will it work fine after it reaches 6gb of usage? Several people have reported several different things. I of course, was looking to buy 1600 or even 1866 Mhz 2x4GB ram sticks for this thing. Under about this mac it says to use only 1067 Mhz. Will there be kernel panics or anything?

    Thanks

    I have the same aluminum MB from late 2008. I have the 2GHz version. It will take 8GB though I'll have you know that I had a great deal of problems in 2009 trying to upgrade the thing to 4GB even so I think the DDR3 RAM was buggy in the beginning. I had tried multiple brands to no avail getting kernel panics. It won't work with anything higher than 1066 MHz. FYI from everymac they state,"*Apple officially supports a maximum of 4 GB of RAM. Originally, this model was only unofficially capable of stably supporting 6 GB of RAM, but as confirmed by site sponsor OWC, it is capable of supporting 8 GB of RAM if updated to Boot ROM Version MB51.007D.B03 and running MacOS X 10.6 "Snow Leopard" or higher."

    This generic Kingston should work as should this Mac-specific Kingston. Price difference is a couple bucks.

    MacBook 5,1 with Lion 10.7.4

    I'm in the same boat as everyone else -- wanting to upgrade to 8 GB RAM

    My MacBook5,1 is running OSX 10.7.4 currently and it shows the MB51.007D.B03 EFI firmware now -- I just bought the Crucial 8 GB PC3-8500 kit today.

    I will swap out the current 4 GB over to the 8 GB tomorrow but my concern now is the Lion (not Snow Leopard 10.6.6) may restrict the 8 GB set
