Made for the 27-inch iMac Retina 5K (Mid 2015)

This 32 GB kit delivers four 8 GB DDR3L SO-DIMMs that match the factory specification for the MF886LL/A model. It is aimed at owners of that 2015 all-in-one who want the maximum 32 GB capacity without mixing module sizes.

204-pin unbuffered modules with major-brand chips

Each stick runs at 1.35 V and carries a CL11 11-11-11 timing profile, matching the DDR3-12800 speed grade the iMac expects. The low-profile SO-DIMM form factor fits the four SO-DIMM slots behind the memory access door without height interference.

DDR3L voltage keeps thermals modest in the sealed

Operating at 1.35 V rather than standard DDR3 voltage reduces heat output inside the compact enclosure, helping the system fans maintain their normal acoustic profile. Power draw stays within the original memory subsystem budget for the 3.3 GHz Core i5 configuration.

Questions about this item

What DDR3L speed and CAS latency does this 32GB kit run at?

The four 8GB modules operate at 1600 MHz with CL11 timing (11-11-11) at 1.35 V.

Will the 204-pin SO-DIMM sticks fit the iMac 27-inch Mid 2015 memory slots?

Yes, the 204-pin DDR3L SO-DIMM form factor matches the four slots in the iMac 27-inch Mid 2015 (model MF886LL/A).

How do I install the modules and what step is often missed?

Power off, unplug, lay the iMac face-down on a soft cloth, remove the memory door, insert each stick until it clicks, replace the door, then reconnect power — the click is the step people skip.
