Mac Pro Memory Models 1.1 and 2.1

Mac Pro 2006-2007
8 Slots
DDR2-667Mhz

The Mac Pro DDR2 series (667Mhz) uses a type of memory called an FB-DIMM. There are eight (8) slots, and the FB-DIMMs are installed in pairs (2x at a time). In order to run 256 Bit Addressing modules are installed in two matched pairs (4x identical modules). The original 1GB is installed as a pair of two 512mb FB-DIMMs. The system maximum is 32GB with the installation of eight (8) 4GB FB-DIMMs. All our Mac Pro DIMMs are Error-correcting Code (ECC) memory.

Heat Sinks: Ramjet uses the only heat sink certified by Apple for use in the Mac Pro. Other brands use heat sink types that cause overheating leading to increased fan usage and slower performance. Our heat sink runs 7 degrees cooler than the folded plate design, and 15 degrees cooler than the flat spreader design of heat sink.

Matched Modules: Ramjet kits contain a matched set of DIMMs. The kit consists of identical brand/model/spec IC's, with matching batch numbers. Our memory will also mate perfectly with Apple original DIMMs.
