Compatible Mac Pro and Xserve models
This 8GB DDR3 1066 ECC registered DIMM is built for Apple Mac Pro towers from Early 2009, Mid 2010 and Mid 2012 with 4-core or 8-core Xeon processors. It also fits Xserve units from Early 2009. The module carries Apple order numbers MB449LL/A, MB535LL/A, MB871LL/A, MC250LL/A, MC560LL/A, MC915LL/A, MC561LL/A, MD770LL/A and MD772LL/A.
ECC registered requirement
The single specification that decides fit is the ECC registered DDR3 1066 (PC3-8500) 240-pin RDIMM format. These Mac Pro and Xserve systems will not accept unbuffered, non-ECC or faster DDR3 modules. The 1.50V voltage and 2Rx4 rank must match the factory memory exactly for the system to recognise the upgrade.
Installation and common issues
Installation requires opening the Mac Pro side panel or Xserve chassis and seating the DIMM in a vacant slot until the ejectors click. The most frequent problem is mixing registered and unbuffered sticks, which prevents boot. Another common error is exceeding the model-specific slot limit, so verify the maximum module count for your exact Mac Pro or Xserve configuration before adding this part.

Soalan tentang produk ini
What does the 1066 MHz speed mean once the module is installed in a Mac Pro?
The module runs at DDR3 1066 MHz (PC3-8500), matching the memory bus speed supported by the listed Mac Pro and Xserve models so the system can use the full rated bandwidth without downclocking.
How does the DDR3 RDIMM interface and ECC registration affect what the memory can do?
As a registered ECC DDR3 RDIMM, it presents a buffered load to the memory controller and provides error-correcting code protection, which is required for stability in the supported Xeon-based Mac Pro and Xserve systems.
What physical slot and form factor does this 240-pin RDIMM need to fit?
It uses a 240-pin DDR3 RDIMM form factor and installs directly into the Mac Pro or Xserve memory slots designed for registered modules.
