4GB DDR3 1333 CL7 SODIMM for 2011 iMac
This 204-pin DDR3 SO-DIMM module delivers 4GB of unbuffered memory at 1333 MHz with CL7 timing and 1.5V operation. It is built with major-brand chips in a 2Rx8 configuration and carries a lifetime warranty from the manufacturer. The stick is validated for the Apple iMac "Core i5" 3.1 27-Inch (Mid-2011) MC814BZ/A.
Who this suits and who should look elsewhere
The module suits owners of the specified 27-inch 2011 iMac who need a single 4GB upgrade to fill one of the four memory slots. Buyers with other iMac models, different DDR generations, or systems requiring ECC or registered memory cannot use this part. It also does not suit anyone needing a 1600 MHz rated module despite the manufacturer highlight mentioning DDR3-12800.
Deciding specification
The validated compatibility with the Apple iMac "Core i5" 3.1 27-Inch (Mid-2011) MC814BZ/A is the single specification that determines whether this upgrade will work in your system.

Soalan tentang produk ini
Will this 204-pin DDR3 SO-DIMM fit the memory slots in my Mid-2011 27-inch iMac?
Yes, the module matches the 204-pin DDR3 SO-DIMM form factor required by the iMac "Core i5" 3.1 27-Inch (Mid-2011) MC814BZ/A, which has four SO-DIMM sockets supporting up to 32 GB total.
What is the correct way to install this SODIMM in the 2011 iMac, and what step do people often miss?
Power off and unplug the iMac, lay it screen-down on a soft cloth, remove the bottom memory access door, insert the module at an angle until the gold contacts are hidden, then press down firmly until both side clips click — the step many miss is pressing hard enough to engage both clips.
Does this 1.5 V CL7 module need any firmware updates or matching pairs to run reliably over time?
No firmware update is needed; the Mac will detect the 1333 MHz CL7 timing automatically. It runs as a single 4 GB stick, so no matching pair is required, and the unbuffered non-ECC design has no moving parts or batteries to replace.
