Targeted iMac upgrade

This kit delivers 16GB of DDR3L 1600MHz memory in two 8GB SODIMM modules built specifically for the 27-inch iMac from Late 2012. The 204-pin unbuffered sticks run at 1.35V with CL11 timings and use major-brand components. It is designed for owners of the MD096LL/A model who need a straightforward capacity increase without compatibility guesswork.

Replacing the base 8GB

The Late 2012 iMac shipped with 8GB as standard and supports up to 32GB across four slots. This two-module kit doubles the factory amount while leaving two sockets free for future expansion. The jump is worthwhile when macOS memory pressure appears during multitasking, virtual machines or large photo libraries, and the system still has empty slots available.

Steady throughput for long sessions

DDR3L 1600 at CL11 provides consistent bandwidth for sustained workloads such as video rendering, batch exports or compiling code. The low-voltage 1.35V operation keeps thermal output modest inside the sealed all-in-one chassis, helping the memory maintain rated speed without throttling during extended use.

Questions about this item

Will these 204-pin DDR3L SODIMM modules fit the four SO-DIMM slots in the 27-inch Late 2012 iMac?

Yes, the kit matches the 204-pin DDR3L 1600 MHz specification and the iMac 27-inch Late 2012 (MD096LL/A, iMac13,2, A1419) has four SO-DIMM slots supporting up to 32 GB total.

What is the correct way to seat the two 8 GB sticks so the iMac recognises the full 16 GB?

Power off, unplug, lay the iMac face-down on a soft cloth, remove the memory compartment door, insert each module at a slight angle until the gold contacts disappear, then press firmly until the side clips click — install one stick per channel for best performance.

If a module fails years later, what replacement does the manufacturer provide?

Computer Memory Solutions backs the kit with a limited lifetime warranty when purchased directly from them, so a defective stick can be replaced under that warranty.
