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.
