I have a 667mhz MacBook Pro duo Intel. I shopped for memory and decided to upgrade from my 2x500mhz cards that came shipped with the book.
From New Egg, i received a Patriot 2gig pc2-5300 card.
I plugged the new card in and it wouldn't work with either of my 500 mhz cards. I plugged the 2gig card in alone and it works fine. Both 500nhz cards work fine independently of the 2 gig.
Is there some compatibility issue between Patriot and the Samsung cards that shipped with my computer or is there another issue? I'd like to take advantage of that second slot particularly if i could slide one of my existing cards in there and get a little extra power.
Any advice on this would be a great help. Thanks for your time,
