96GB DDR3 Kit for Mac Pro 2009/2010

This 96GB kit contains six 16GB DDR3 ECC Registered DIMMs built for the Apple Mac Pro Early 2009 8-Core and Mid 2010 8-Core models. It matches the required PC3-8500 speed grade and 240-pin RDIMM form factor. The modules operate at 1.50V and use major brand chips for reliability in these specific workstations.

DDR3 1066MHz bandwidth limits throughput

The DDR3 1066/1067MHz interface caps memory bandwidth at the PC3-8500 level, which restricts data throughput compared to later DDR generations. ECC Registered operation adds a clock cycle of latency for error correction, a requirement for the Xeon 5520, 5550, 5570 and 5620 processors used in these systems. This kit cannot run at speeds higher than the platform's native memory controller allows.

Six-slot installation requires matched population

Installing all six 16GB modules fills every available DIMM slot on the Mac Pro memory risers, leaving no room for future expansion. The 4Rx4 rank configuration demands correct riser population order; misplacing modules prevents the system from booting or recognising the full 96GB capacity. Buyers needing more than 96GB cannot use this platform.

Questions about this item

How do I know if my Mac Pro needs the 6x16GB kit or a different capacity?

This kit provides 96GB across six 16GB modules and is validated for Mac Pro models MacPro4,1 and MacPro5,1 with 8-core Xeon processors listed in the compatibility data.

What does the 1066/1067MHz rating mean once the memory is installed?

The modules run at DDR3 1066MHz (PC3-8500) with a CAS latency of 4Rx4, delivering the rated throughput when populated in all six slots of a supported Mac Pro.

Will the 240-pin RDIMM interface work in my Mac Pro's memory slots?

Yes, the 240-pin DDR3 ECC Registered RDIMM form factor matches the slot specification for the listed Early 2009 and Mid 2010 8-core Mac Pro towers.
