32GB DDR3 1066 ECC RDIMM kit

This 32GB kit contains four 8GB registered ECC modules that run at DDR3 1066 (PC3-8500) with a 1.50V supply. It is built for Apple Mac Pro models from Early 2009, Mid 2010 and Mid 2012 plus Xserve units from Early 2009. Each module uses a 240-pin RDIMM form factor and major-brand chips.

Sustained-load behaviour

Registered buffering and ECC correction keep data integrity stable when all four channels are fully populated and the system runs continuous workloads. The 2Rx4 organisation spreads access across ranks, helping the memory controller maintain throughput during long compile jobs, virtualisation tasks or large dataset processing.

DDR3 1066 interface limits

The PC3-8500 standard caps peak bandwidth at the rated 1066/1067 MHz clock, so total throughput cannot exceed that ceiling regardless of module count. Builders needing higher memory speeds or greater capacity per slot cannot meet those needs with this DDR3 generation.

Perguntas sobre este artigo

How much power does each 8 GB DDR3 1066 ECC RDIMM draw at 1.50 V?

Each module operates at 1.50 V; total kit power depends on system load and the number of populated slots.

Which Mac Pro or Xserve models must I already own for this 4 x 8 GB kit to work?

Compatible systems include Mac Pro Early 2009 4-Core/8-Core, Mid 2010 4-Core/8-Core, Mid 2012 4-Core, and Xserve Early 2009 4-Core/8-Core.

Will these registered ECC DDR3 1066 modules run alongside the original Apple memory in a Mac Pro 4,1?

Yes, the 2Rx4 registered ECC RDIMMs are designed to match the Mac Pro 4,1 memory specification and can be mixed with factory modules.
