32GB DDR3 1066 ECC kit for Mac Pro/Xserve

This 32GB kit contains eight 4GB DDR3 1066 ECC UDIMM modules built for Apple Mac Pro (Early 2009, 8-Core; Mid 2010, 8-Core) and Xserve (Early 2009, 8-Core). The memory runs at PC3-8500 speed with 1.50V unbuffered ECC operation. It matches Apple order numbers MB535LL/A and MC561LL/A and model IDs MacPro4,1, MacPro5,1 and Xserve3,1.

Not for non-ECC or registered slots

Buyers whose systems require non-ECC memory or registered DIMMs cannot use this kit. It is also unsuitable for Mac Pro or Xserve models that are not the listed 8-Core variants, or for any platform using a different DDR generation or pin count.

DDR3 1066 ECC UDIMM 240-pin specification

The decisive specification is the DDR3 1066 ECC UDIMM 240-pin form factor with unbuffered error correction. Only systems that explicitly support this exact module type will accept the kit.

Questions about this item

Does my Mac Pro need eight free DDR3 240-pin slots to use this 32 GB kit?

Yes, the kit contains eight 4 GB modules and each requires one DDR3 240-pin ECC UDIMM slot on the Mac Pro or Xserve logic board.

Will these DDR3 1066 modules run correctly if I keep my existing 1066 MHz ECC UDIMM sticks installed?

They will operate together at 1066 MHz because all modules share the same DDR3 1066 PC3-8500 ECC unbuffered specification.

How can I confirm the full 32 GB is recognised after installing the eight modules?

Open About This Mac or System Report; the memory section should list 32 GB total across eight slots at 1067 MHz DDR3 ECC.
