Mac Memory Kit

This 8 GB kit contains two 4 GB DDR3 1333 SO-DIMM modules built for select Apple computers. It targets owners of MacBook Pro, iMac or Mac mini models from 2010 and 2011 who need a straightforward capacity increase.

DDR3 1333 SO-DIMM 204-Pin

The modules run at DDR3 1333 (PC3-10600) with a 1.50 V supply, non-ECC unbuffered operation and a 2Rx8 rank. That exact specification decides whether the memory will be recognised and stable in the listed machines.

Apple Model Compatibility

Compatibility is defined by Apple order numbers such as MC309LL/A, MC812LL/A and MD311LL/A, and by model identifiers including iMac11,2, MacBookPro8,1 and Macmini5,1. Systems outside those identifiers will not accept the kit.

Questions about this item

How does the 1333 MHz speed affect everyday tasks on my 2011 MacBook Pro?

The 1333 MHz DDR3 modules match the native memory bus of the 2011 MacBook Pro, so the system runs at its rated bandwidth without downclocking, giving you the full 8 GB capacity for smoother multitasking and faster application launches.

Will the PC3-10600 SODIMM standard limit performance on a Mid 2011 iMac?

PC3-10600 is the JEDEC designation for DDR3 1333, which is exactly the speed the Mid 2011 iMac memory controller expects, so there is no bottleneck — the modules operate at the system's maximum supported memory rate.

Do the 204-pin SO-DIMM modules fit the memory slots in a Mac mini (Mid 2011)?

Yes, the 204-pin SO-DIMM form factor is the physical standard used by the Mac mini (Mid 2011), and the kit includes two 4 GB sticks that populate both available slots for the full 8 GB upgrade.
