Apple iMac Models

Within the iMac family there are 6 distinct models that each have their own specific architectures. Our exclusive premium certified HyperVelocity modules deliver the highest possible performance you can get for your model iMac. Please select your specific model in order to choose the correct memory modules.

Whenever applicable, Mac RAM Direct will spec upgrades in the form of modules capable of faster speeds than originally supplied. Remember, faster RAM is like Premium gasoline where even if your car uses 87 octane Regular, she'll purr like a kitten with the higher octane juice. The same holds true for RAM. Enjoy!
