higher density memory upgrade options.



Special 32GB module use information: Due to processor design and memory architectures, 32GB module utilization occurs at
a bus speed of 1066MHz with Apple Mac Pro
2013 E5-16XXv2 4-Core, 6-Core, and 8-Core
processor equipped models, 800MHz with factory
12-Core or after-market E5-26XX equipped
models. Utilization of 2 or more 32GB modules
