Compatibility — iMac 21.5 Mid 2011 27 Mid 2010 2011

This 32 GB kit is built for the Apple iMac 21.5-inch Mid 2011, the 27-inch Mid 2011 and the 27-inch Mid 2010 Core i5 and i7 models. It matches the Apple order numbers MC309LL/A, MC812LL/A, MC813LL/A, MC814LL/A, MD063LL/A, MC511LL/A and MC784LL/A and the model identifiers iMac11,3, iMac12,1 and iMac12,2.

Who this suits — who should look elsewhere

Owners of the listed iMacs who need the maximum 32 GB capacity in a four-module kit will use every slot. Builders working on any other Mac, on a Windows laptop or on a desktop that requires a different pin count, voltage or memory generation cannot use this kit.

Deciding specification — DDR3 1333 204-pin SODIMM

The modules are DDR3 1333 MHz PC3-10600 SO-DIMMs with 204 pins, 1.50 V operation, non-ECC unbuffered 2Rx8 organisation. If your system calls for this exact combination the kit will work; if it calls for any other speed, pin layout or voltage you need a different part.

商品問答

Will 1333MHz DDR3 actually run at that speed in my Mid 2011 iMac?

The modules are rated at 1333MHz PC3-10600, and the supported iMac models run DDR3 at that native bus speed, so the memory will operate at its rated frequency.

Does the 204-pin SODIMM interface limit total capacity on these iMacs?

Each slot accepts a 204-pin DDR3 SODIMM; the four slots in the compatible Mid 2010 and Mid 2011 iMacs allow the full 32GB kit (4 x 8GB) to be installed.

Will the 1.50V unbuffered 2Rx8 modules fit the memory bay in a 21.5-inch Mid 2011 iMac?

Yes, the SODIMMs are standard height with no heat spreader and match the 1.50V unbuffered 2Rx8 specification required by the 21.5-inch and 27-inch Mid 2010/2011 iMac models.
