Product identity

This kit delivers 16 GB of DDR3 1333 MHz memory in two 8 GB SO-DIMM modules. It is built for the Apple iMac Core i5 2.5 21.5-Inch Mid-2011 and uses 204-pin unbuffered non-ECC chips at 1.5 V with CL9 timing.

Who it suits

Owners of the specified iMac model who need the maximum 16 GB upgrade from a trusted brand will find guaranteed compatibility. Buyers who want more storage, a different memory generation, ECC support or modules for any other system should look elsewhere.

Installation notes

The SO-DIMM slots are accessible behind the memory door on the bottom edge of the iMac; no tools are required beyond a Phillips screwdriver for the door. The usual issue is failing to seat both modules fully until the latches click, which leaves the system seeing only half the expected capacity.

Spurningar um þessa vöru

Do I need a 2011 iMac with four SO-DIMM slots to use both 8GB modules from this 16GB kit?

The kit is validated for the Mid-2011 21.5-inch iMac which has four slots and a 32GB maximum, so both 8GB modules will be recognised when all slots are populated.

Will these CL9 1333MHz modules run at the correct speed if I leave older CL11 1333MHz sticks in the other two slots?

The memory controller will operate all installed modules at the lowest common speed and latency, so the CL9 sticks will drop to CL11 timing to match the older pair.

How can I confirm the full 16GB is active after installing the two 8GB sticks?

Open About This Mac or System Report; it should show 16GB total memory with two 8GB DDR3 1333MHz modules listed in the memory slot detail.
