This Netlist Memory Upgrade Kit has been designed and built exclusively for use in Apple Mac Pro Quad Xeon systems. Not only are these modules built using an Apple Proprietary Heat-Spreader and in compliance with the Apple Thermal Specifications which exceed those of standard JEDEC, these exact same modules are Apple Certified Production modules for use in factory configurations.
OWC is proud to offer the best possible Mac Pro Memory solutions available.
Apple specifically designed the Mac Pro with more space between each slot to accommodate the Apple Proprietary Heat-Spreader for thermal requirements. Use of Apple's spreader solution and the highest grade, thermally tolerant components ensure that these Mac Pro Quad Xeon Memory Upgrade Kits will provide a lifetime of reliable and trouble-free operation.
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 our own testing, we have 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. It is very disappointing that many other memory providers continue to list and misrepresent such JEDEC modules, that lack the proper heat-spreader, as being correct for the Mac Pro.

The Apple Mac Pro is an amazing machine.
