Mac Specs > By Capability > Actual Maximum RAM > Mac Pro Models

The actual maximum RAM of each Mac Pro is listed below along with its compatible RAM type, default amount of RAM pre-installed, common identifiers suitable to identify a Mac Pro in order to determine its RAM capacity, and more.

If you are not sure which Mac Pro you have, and the Model Identifier and EMC Number below are not sufficient for identification, you also may look it up with other identifiers -- including its Serial Number -- with EveryMac.com's Ultimate Mac Lookup feature. If you need more help, refer to Mac Identification.





Click the triangle to the left of a system to open "Quick Specs" -- the two most relevant identifiers for RAM capacity, full RAM details and links to buy compatible RAM from site sponsors -- and click on the name or image for complete specifications.

Asterisks indicate important details (such as a different "official" maximum RAM capacity listed within "Quick Specs" or other details on the complete specs page).
