16GB DDR3L SO-DIMM kit for late-2012 iMac 27

This 16GB kit contains two 8GB DDR3L 1600 SO-DIMM modules built for the Apple iMac "Core i5" 2.9 27-Inch (Late 2012). The 204-pin unbuffered memory runs at 1.35V with CL11 timing. It targets owners of that specific iMac model who want to reach the system's 32GB maximum using all four slots.

Sustained-load behaviour with 1.35V DDR3L

The low-voltage DDR3L chips operate at 1.35V, reducing heat output during long work sessions compared with standard 1.5V DDR3. CL11 11-11-11 latency delivers consistent throughput for everyday multitasking and media editing. Major-brand chipsets and 2Rx8 organisation support stable operation when all four slots are populated up to the 32GB limit.

Straightforward slot access, watch the slot count

Installation requires opening the iMac's memory door and inserting the 204-pin SO-DIMMs into the available slots; the kit provides two 8GB sticks. The machine accepts up to 32GB across four sockets, so buyers needing the full 32GB must add a second identical kit. No heat spreader is fitted, keeping module height low for the tight SO-DIMM bay.

Questions about this item

Does the 1.35V DDR3L voltage keep heat low when the iMac runs all day?

The modules operate at 1.35V DDR3L, which is the lower-voltage standard for this platform and helps limit thermal output during extended use.

What must the iMac already have for this 204-pin SO-DIMM kit to install?

Your Late 2012 27-inch iMac needs four empty or populated 204-pin SO-DIMM slots; the kit provides two 8GB sticks to fill two of them.

Will this 16GB kit work with the iMac's 32GB maximum capacity and four sockets?

Yes, the 16GB (2x8GB) kit fits within the 32GB limit across four sockets, leaving room for two more modules if you keep existing memory.
