Mac Late 2012 27-Inch Upgrade Kit

This 32 GB kit contains four 8 GB DDR3L 1600 SO-DIMM modules built for the Apple iMac "Core i5" 3.2 27-Inch (Late 2012). Each stick runs at 1.35 V with CL11 timing and uses 204-pin unbuffered, non-ECC construction. The package delivers the full 32 GB maximum the system accepts across its four slots.

Suitable For Max-Capacity Mac Builds

Owners of the specified Late 2012 27-Inch iMac who want the highest supported memory total will use all four slots with this matched set. Buyers with other iMac models, different release years, or machines that require ECC or registered memory cannot use this kit.

DDR3L 1600 CL11 1.35 V Specification

The modules operate at DDR3L 1600 (PC3L 12800) with 11-11-11 latency at 1.35 V. This exact speed, voltage and timing combination is what the target iMac expects; deviations will prevent the system from booting or running stably.

Questions about this item

Do I need all four SO-DIMM slots free to install this 32GB kit?

The iMac Late 2012 has four slots and a 32GB maximum, so the kit fills every slot; no empty sockets are required beforehand.

Will the 1.35V DDR3L modules run at 1600MHz alongside any existing DDR3 memory I keep installed?

The Mac firmware sets a single speed for all installed memory; mixed voltages or speeds will default to the lowest common setting.

How can I verify the full 32GB is recognised after installation?

Open About This Mac or System Report — it should show 32GB total across four 8GB DDR3L 1600MHz modules.
