Apple G5 PowerMac Models

Within the G5 PowerMac family there are 2 distinct models that each have their own specific architectures. The Original 1st Generation models that use DDR RAM and the later 2nd Generation machine that use DDR2 RAM. Our exclusive premium certified HyperVelocity modules deliver the highest possible performance you can get for your G5 PowerMac.

  Not 100% Sure which RAM is correct for your model? Go to your "About this Mac" then "Memory" and "More Info", if the speed shown is PC2-4200 then yours is the later "2nd Generation" model, listed on the top of this page. If the speed shown is PC-3200 then you have one of the original "1st Generation" models, listed down further. Please carefully select your specific model in order to choose the correct memory modules.

Whenever applicable, Mac RAM Direct will supply upgraded modules capable of faster speeds than the factory originally supplied. Faster RAM is not unlike Premium gasoline for your vehicle, where even if your auto can use 87 octane Regular, she'll purr like a kitten with the higher octane products. Similar qualities hold true for RAM. Enjoy!

Please select your specific Power Mac model ... or just scroll down the page from newest to oldest models:
