Kit for Apple Mac Pro Quad Core 3.2GHz

This 4GB kit contains two 2GB DDR2-667 fully buffered DIMMs built for the Apple Mac Pro Quad Core 3.2GHz. The modules use 240-pin DDR2 SDRAM with ECC and run at 1.8V. They are intended for server-grade memory slots in this specific workstation.

Fully buffered DDR2 ECC requirement

The Mac Pro Quad Core 3.2GHz requires fully buffered DDR2 ECC memory; standard unbuffered or non-ECC DDR2 will not function. These modules meet the CL5 5-5-5 timing and PC2-5300 specification demanded by the system's memory controller.

Capacity and headroom

Each of the two memory cards accepts four modules for a maximum of 16GB per card and 64GB total across eight slots. This 4GB kit occupies two slots; the remaining six slots allow further expansion up to the 64GB ceiling supported by third-party configurations.

Preguntas sobre este artículo

How does the 667 MHz speed affect real-world performance in a Mac Pro?

The modules run at DDR2-667 (PC2-5300) with CL5 timing, matching the memory controller on the 2.8, 3.0 and 3.2 GHz Xeon models so the system operates at its rated bandwidth.

What does the fully buffered DIMM interface mean for compatibility and capacity?

Fully Buffered DIMM architecture is required by the Mac Pro memory cards; the kit installs in pairs across the eight slots, supporting up to 64 GB when all slots are populated with compatible modules.

What physical requirements must the Mac Pro meet to accept these 240-pin modules?

The Mac Pro uses 240-pin DDR2 FB-DIMM slots on dedicated memory cards; a special heat sink is required and modules must be installed in matched pairs per card.
