Memory Module 1GB 667MHz DDR2 FB DIMM ECC - 2x512MB For maximum performance, Mac Pro uses 667MHz DDR2 fully buffered ECC memory, a new industry-standard memory technology that allows for more memory capacity, higher speeds, and better reliability. When using all four memory channels, Mac Pro has a 256-bit wide memory path for a maximum memory bandwidth of 21.3GB per second. To achieve maximum bandwidth, four or more DIMMs should be installed in a Mac Pro.
