Memory Kit for 27-inch iMac

This 16 GB kit contains two 8 GB DDR3 SO-DIMM modules rated at 1333 MHz with CL9 timing. It is built for the 27-inch iMac models running a 3.4 GHz Core i7 or a 3.1 GHz Core i5 and matches the factory DDR3-10600 specification.

Thermals and Power

Each module operates at the standard 1.5 V DDR3 voltage and carries no heat spreader, relying on the iMac’s internal airflow. Unbuffered, non-ECC chips keep the electrical load low, so the memory adds minimal heat and draws no extra power beyond the stock configuration.

Build Fit

The 204-pin sticks install directly into the iMac’s four SO-DIMM slots, leaving two sockets free for a future upgrade to the 32 GB ceiling. Buyers who need ECC, registered DIMMs or a different DDR generation cannot use this kit.

Perguntas sobre este artigo

How do I install the 204-pin DDR3 SO-DIMM modules into the iMac 27-inch and what step is often missed?

Power off, unplug, lay the screen face-down on a soft cloth, press the memory door button to open the compartment, eject any existing modules by spreading the side clips, align the notch on each 8 GB stick with the slot key, press firmly until the clips snap shut, then replace the door before turning the iMac upright.

What maintenance or replacement will the CM10246410600SODRH kit need over time?

The unbuffered non-ECC DDR3 modules have no moving parts and require no scheduled maintenance; replacement is only necessary if a stick fails, which is covered by the manufacturer's limited lifetime warranty when purchased directly from Computer Memory Solutions.

What limit appears first when the iMac 3.4 GHz Core i7 runs sustained workloads with 16 GB installed?

Apple officially supports 16 GB for this model, so the firmware-recognised capacity ceiling is reached before any thermal or voltage throttle from the 1.5 V CL9 memory itself.
