System-specific kit for Late 2014 iMac

This 32 GB kit contains four 8 GB DDR3L 1600 SO-DIMM modules built for the Apple iMac Retina 5K 27-inch (Late 2014) MF886LL/A. It fills all four memory slots to reach the machine's maximum supported capacity of 32 GB. The unbuffered, non-ECC design matches the factory specification for this model. Buyers needing ECC, registered DIMMs or higher speeds cannot use this kit.

Four matched modules eliminate mixed-timing risk

The package supplies four identical 2Rx8 sticks rated CL11 11-11-11 at 1.35 V. Using a matched quad-channel set removes the instability that can appear when mixing modules of different rank, latency or voltage. No heat spreaders are included, keeping the low-profile form factor required by the slim iMac chassis. No software or additional accessories are bundled.

Direct slot installation with no tools

Each 204-pin module inserts vertically into the SO-DIMM slots accessible behind the memory compartment door; no screws or cables are involved. The tight clearance inside the 27-inch Retina enclosure means modules must be fully seated before the door is closed, otherwise the system will not recognise the full 32 GB. The kit is validated only for the MF886LL/A iMac; other Macs or PC platforms are not supported.

Questions about this item

Will the 204-pin DDR3L 1600 modules need replacement after a certain period?

The modules are sold new with a limited lifetime warranty from the manufacturer when purchased directly, so no scheduled replacement is expected under normal use.

What limit appears first when the iMac runs the 32GB kit at full load for hours?

The system's maximum supported memory of 32GB across four sockets is reached by this kit, so capacity is the first ceiling you hit under sustained workloads.

How much heat and power do the four 1.35V sticks produce during all-day operation?

Each stick runs at 1.35V DDR3L voltage without a heat spreader, keeping thermal output and power draw low for continuous use in the 27-inch Late 2014 iMac.
