MacBook Pro and Memory Compatibility issues?

Double King · 11-30-2007, 06:47 AM

Hi all,

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,

When mixing RAM it is always a hit and miss affair due to manufacturers using different components for different models and such.
That is generally why we advise people to buy the same make and model of ram if possible or when buying ram for a new build buy from a decent manufacturer so if you decide to upgrade later there is a better chance of getting the same type of ram
