Mac Pro Late 2013
4 slots

The latest model of the Mac Pro takes DDR3-1866Mhz RAM.  The machine has four slots that can take up to 32GB* per slot for a maximum upgrade of 128GB of RAM.

The DDR3-1866 DIMMs for the Mac Pro require a Thermal Sensor for full performance and compatibility. Many 3rd party Mac Pro DIMMs do not include this sensor. Ramjet memory always conforms 100% to the Apple spec, and these DIMMs include the Apple thermal sensor.

Tri-channel memory configuration gives a slight performance advantage. The DDR3-1866 DIMMs for the Mac Pro will run 1-3% faster if they are installed in matched sets of three (tri-channel). You may add DIMMs in any combination, but performance will suffer slightly if the DIMMs are not matched 3x at a time.

Non-Mixable 16GB and 32GB DIMMs: 16GB and 32GB DIMMs can ONLY be used with identical 16GB or 32GB DIMMs from the same batch (i.e. ordered at the same time.)  16GB and 32GB DIMMs can NOT be mixed with each other.

*32GB DIMMs: Due to configuration of the 2013 Mac Pro processor, 32GB modules will register at a bus speed of 1066Mhz.  All other size modules register at a bus speed of 1866Mhz.

Matched Modules: The Ramjet kits for the Mac Pro DDR3-1866 contain a matched set of DIMMs. The kit will consist of identical brand/model/spec IC's. They will be from a single batch, and will have matching series numbers. This ensures maximum performance, and perfect compatibility.
