Ramjet 4GB DDR3-1066 ECC DIMM PC3-8500 DDR3 1066Mhz Kit for Apple Mac Pro (1x 4GB)

One 4GB, PC3-8500, DDR3-1066, 1066Mhz, 8.5GB/s Bandwidth, CAS 7-7-7-20, 5ns Cycle Time, ECC, Dual Rank, RoHS Certified, 512x72, 1.5V, 240pin DIMMs.

This kit contains matched DIMM modules, which are specifically designed and SPD configured for the "Nehalem" and "Westmere" Mac Pro.

This DIMM includes the Apple Thermal EPROM Sensor.

These modules are compatible with the latest Apple Firmware.

Configuration Information:
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. MacMemory Net memory always conforms 100% to the Apple spec, and these DIMMs include the Apple thermal sensor.

System Maximum: The system maximum in the 3rd Generation Mac Pro is 64GB (4x 16GB) in the 4-slot models, or 96GB (6x 16GB) in the 8-slot models.

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 or six modules (tri-channel). You may add DIMMs in any combination, but performance will suffer slightly if the DIMMs are not matched.

Mixing DIMMs: These 4GB MacMemory Net EEC DIMMs can be mixed with the Apple original DIMMs in your Mac Pro.
