Product Information


Upgrade the memory in your 2013 Mac Pro (MacPro6,1) using the 128GB DDR3 1333 MHz RDIMM Memory Kit from OWC / Other World Computing.

This memory kit features a total capacity of 128GB, which is made of up four 32GB modules. It also has a clock speed of 1333 MHz, a bus speed of PC3-10600, and a 240-pin RDIMM form factor. It operates using 1.5V, has a CAS Latency of 9-9-9-24, a module bandwidth of 10.6 GB/s, a component configuration of 2048M x 72, is registered, and is equipped with ECC technology.

Registered memory places less electrical loads on the memory controller and allows single systems to remain stable with more memory modules than they would have otherwise. By offering ECC (Error Checking and Correcting) technology, this RAM will help your workstation encounter fewer errors that can corrupt data sets and introduce system issues. Additionally, this memory module is compatible with Apple Specified Thermal Sensor, which ensures that the RAM maintains a safe thermal operating range. 

Important Product Note

Apple Mac Pro 2013 models utilise 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 therefore need to be removed in order to utilise these higher density memory upgrade options.

Special 32GB module use information: Due to processor design and memory architectures, 32GB module utilisation occurs at a bus speed of 1066MHz with Apple Mac Pro 2013 E5-16XXv2 4-Core, 6-Core, and 8-Core processor equipped models and at 800MHz with factory 12-Core or after-market E5-26XX equipped models. Utilisation of 2 or more 32GB modules minimum is recommended and overall performance with applications and workflows able to utilise higher available memory remains exceptional.
