Upgrade the memory in your 2013 Mac Pro (MacPro6,1) using the 96GB DDR3 1333 MHz RDIMM Memory Kit from OWC / Other World Computing. This memory kit features a total capacity of 96GB, which is made of up three 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.
Note: Due to processor design and memory architectures, 32GB module utilization occurs at a bus speed of 1066 MHz with Apple Mac Pro 2013 E5-16XX v2 Four-Core, Six-Core, and Eight-Core processor-equipped models, and 800 MHz with factory 12-Core or after-market E5-26XX equipped models. Utilization of a minimum of two or more 32GB modules is recommended and utilization of overall performance with applications and workflows able to utilize higher available memory remains exceptional.
