Targeted Mac Pro and Xserve Memory Upgrade

This 8 GB kit contains two 4 GB DDR3 1066 ECC UDIMM modules built for specific Apple Mac Pro towers from Early 2009 through Mid 2012 and Early 2009 Xserve units. It matches the PC3-8500 specification and uses unbuffered ECC chips on a 240-pin form factor. The modules are designed for systems identified by model IDs MacPro4,1, MacPro5,1 and Xserve3,1.

Sustained Workload Stability

ECC circuitry detects and corrects single-bit errors during continuous operation, helping prevent data corruption in long rendering, virtualization or server tasks. The 1.50 V modules run at the native 1066 MHz bus speed without overclocking, so thermal output remains consistent with the original system design. Unbuffered layout keeps latency low for the memory controller in these Xeon-based platforms.

Direct Slot Installation

Modules insert vertically into the 240-pin DDR3 slots on the Mac Pro or Xserve memory risers; no tools or firmware updates are required. The kit is validated for the listed Apple order numbers and model numbers, so mismatched rank or voltage issues are avoided. Buyers needing larger capacities or registered DIMM support for other Mac models cannot use this kit.

Preguntas sobre este artículo

How much heat does the 1.50 V DDR3 1066 ECC kit add when the Mac Pro runs all day?

The modules run at standard 1.50 V DDR3 voltage, so they add only the normal heat expected from two 4 GB unbuffered ECC DIMMs under continuous load.

What must the Mac Pro already have for this 240-pin DDR3 1066 ECC UDIMM kit to work?

The Mac Pro must be one of the listed Early 2009, Mid 2010 or Mid 2012 models with Xeon processors such as the 2.26 GHz E5520 or 2.93 GHz X5570 and have free 240-pin DDR3 ECC UDIMM slots.

Will this DDR3 1066 ECC kit run at the correct speed alongside the original 1066 MHz memory in a 2009 Mac Pro?

Yes, the kit matches the PC3-8500 1066/1067 MHz spec of the factory memory, so all installed DIMMs will operate at the same 1066 MHz speed.
