OWC 4GB modules require that all installed modules be of the same p/n OWC 4GB modules. Other existing Apple or 3rd party 1GB, 2GB, 8GB and 16GB modules are not supported for use with these kits and need to be removed when these modules are added.

OWC 8GB modules require that all installed modules be of the same p/n OWC 8GB modules. Other existing Apple or 3rd party 1GB, 2GB, 4GB and 16GB modules are not supported for use with these kits and need to be removed when these modules are added.

OWC 16GB modules require that all installed modules be of the same p/n OWC 16GB modules. Other existing Apple or 3rd party 1GB, 2GB, 4GB and 8GB modules are not supported for use with these kits and need to be removed when these modules are added.

Apple Mac Pro 2013 models utilize ECC non-Registered for 4GB and 8GB per slot options and ECC Registered for 16GB (and larger) per slot options. Any existing 4GB and 8GB ECC non-Registered modules cannot be mixed with 16GB and larger ECC-Registered modules and will need to be removed in order to utilize these 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 minimum is recommended and utilization of overall performance with applications and workflows able to utilize higher available memory remains exceptional.
