Four or More FB-DIMMs installed provides for best performance

For maximum performance, the latest Mac Pro uses 800MHz 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.

Please note: The fully buffered DIMMs made by Apple include a unique heat sink that provides more efficient cooling than other FB-DIMMs. These FB-DIMMs require less airflow to stay cool and allow the internal fans to spin at slower speeds, improving system acoustics. FB-DIMMs made by other manufacturers that do not include a sufficient heat sink may cause the fans to run faster (and louder) or the memory chips to run slower so as not to overheat.

Apple specifically designed the Mac Pro with more space between each slot to allows the use of a larger heat-spreader on each module. The larger heat-spreader and the use of the highest grade, thermally tolerant components ensures that these will provide a lifetime of reliable and trouble free operation.

Warning

Apple notes that using parts with the standard heat-spreader and which only meet JEDEC standard specifications can result in higher fan speeds due to increased internal temperatures and system controlled reduction of memory performance to prevent thermal overload. In testing, it was found that use of such modules leads to ECC errors and ultimate system lock ups as such modules reach significantly higher temperatures than those of Apple's qualified spec.

Two well known memory manufacturers originally listed their own JEDEC standard modules as being Mac Pro compatible. Within days of doing so, each removed this compatibility support after reports and testing which made clear JEDEC standard modules were not reliable in the Mac Pro.

JEDEC is the leading developer of standards for the solid-state industry. Almost 3300 participants, appointed by some 295 companies work together in 50 JEDEC committees to meet the needs of every segment of the industry, manufacturers and consumers alike. The publications and standards that they generate are accepted throughout the world. All JEDEC standards are available online, at no charge.
