Apple Mac Pro 1,1 Memory

  • MAXIMUM MEMORY: 32GB/48GB w/RDIMMs and 64 Bit OS


NOTE: The Mac Pro uses triple channel DDR3 memory. Data Memory Systems' DDR3 ECC Modules are manufactured using an Apple qualified Thermal Sensor. Supports 32GB of RAM using four 8GB memory modules.  The 6-Core Mac Pro supports 16GB registered DIMMs (RDIMMs) but only three can be used for a total of 48GBs  RDIMMs cannot be mixed with unregistered DIMMs. The DMS 16GB RDIMMs can not be mixed with other chips on this page.

To use more than 32GB of RAM you must boot into 64 bit mode.  Standard 32 bit will show you all the memory in the System Profiler but Activity Monitor will only show you the utilized RAM.
