Apple iMac Mid-2011 Memory Kit

This kit supplies two 4 GB DDR3 SO-DIMM modules for a total of 8 GB. The sticks run at 1333 MHz with CL7 timing and 1.5 V unbuffered operation. They are built to match the Apple iMac Core i7 2.8 21.5-Inch Mid-2011 specification. Each module uses a 204-pin layout and major-brand chipsets.

Ideal for iMac 2011 Upgrades

Owners of the named iMac model can install both sticks to reach 8 GB without compatibility guesswork. Buyers who need more than 8 GB or who are repairing a different computer should look elsewhere. The kit does not support ECC or registered memory configurations.

DDR3 1333 CL7 Specification

The decisive figure is the DDR3 1333 CL7 rating at 1.5 V in a 204-pin SO-DIMM form factor. If the target system requires a different speed, voltage or pin count, these modules will not function. Verified compatibility is limited to the listed iMac.

Questions about this item

Should I pick the 2×4 GB kit or a single 8 GB module for this iMac?

The kit provides two 4 GB sticks, letting you fill two of the four slots and leave room for future expansion up to 32 GB total.

Will the CL7 timing at 1333 MHz actually run at that speed in the Mid-2011 iMac?

The modules are rated DDR3-1333 CL7, and the iMac's memory controller supports that speed, so they will operate at the rated frequency and latency.

Does the 204-pin DDR3 SO-DIMM interface limit the maximum capacity I can install?

The iMac has four SO-DIMM sockets and a 32 GB maximum, so this 8 GB kit uses half the slots and stays within the supported limit.
