Apple Mac DDR3 1066 SODIMM Kit

This 8 GB kit contains two 4 GB unbuffered SODIMM modules rated at DDR3 1066 (PC3-8500) and 1.50 V. It is built for owners of specific 2008-2010 MacBook Pro, MacBook, iMac and Mac mini models that require 204-pin DDR3 memory.

Suits Macs listed in the Apple model IDs.

The modules are validated for Apple model identifiers such as MacBookPro5,1 through MacBookPro7,1, iMac9,1 and iMac10,1, Macmini3,1 and Macmini4,1. Machines outside this list, or later Macs that use a different memory generation, will not accept these SODIMMs.

DDR3 1066 speed and 204-pin SODIMM form factor

The decisive specification is the DDR3 1066 (PC3-8500) rating combined with the 204-pin SO-DIMM layout; only Macs designed for this exact speed and pin count will recognise and run the memory at its rated frequency.
