OWC DDR3 1066 MHz UDIMM Mac Overview

Upgrade the memory in select 2009-2010 Mac Pro systems or compatible PC desktops/servers using the 128GB DDR3 1066 MHz UDIMM Memory Kit from OWC / Other World Computing. This memory kit features a total capacity of 128GB, which is made up of eight 16GB modules. It features a clock speed of 1066 MHz, a bus speed of PC-8500, and a 240-pin UDIMM form factor.

By offering ECC (Error Checking and Correcting) technology, this RAM will help your workstation encounter fewer errors that can corrupt data sets and introduce system issues. Additionally, this memory module is compatible with Apple Specified Thermal Sensor, which ensures that the RAM maintains a safe thermal operating range.

OS X versions prior to 10.9 Mavericks are unable to utilize more then 96GB RAM due to an operating system limitation. 128GB can be fully utilized by a 2009-2010 Mac Pro running OS X 10.9 Mavericks or later, running Bootcamp with 64-bit versions of Windows XP and later, or running 64-bit versions of Linux.

To utilize over 32GB of memory in your Mac Pro using 10.6.x or greater, you must boot into 64-bit mode. In 32-bit mode, all installed memory will show in system profiler but only up to 32GB will be actively used by the computer.

All installed RAM modules must be of the same type. Other existing Apple or 3rd-party modules are not supported for use with this kit and need to be removed when these modules are added.
