Mac Pro Early 2009 to Mid 2010
4 slot version
DDR3-1066Mhz

The DDR3-1066 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. All our Mac Pro DIMMs are Error-correcting Code (ECC) memory.

Tri-channel memory configuration gives a slight performance advantage. The DDR3-1066 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.

8GB and 16GB modules: In order for the Model ID 4,1 to recognize and utilize 8GB or 16GB modules, your OS must be upgraded to Lion or above.

Non-Mixable 16GB DIMMs: 16GB DIMMs can ONLY be used with identical 16GB DIMMs from the same batch (i.e. ordered at the same time.)

Matched Modules: The Ramjet kits for the Mac Pro DDR3-1066 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.

PC3-8500, DDR3-1066, 1066Mhz, 8.5GB/s Bandwidth, CAS 9-9-9-24, 5ns Cycle Time, ECC, Dual Rank, RoHS Certified, 256x72, 1.5V, 240pin DIMMs.
