Purpose-built 16 GB kit for 2015 iMac 27-inch

This 16 GB kit contains two 8 GB DDR3L SODIMM modules rated at 1600 MHz with CL11 timings. It is designed specifically for the Apple iMac Retina 5K 27-inch Mid 2015 model MF885LL/A. The unbuffered, non-ECC sticks operate at 1.35 V and use major-brand chipsets.

Check your iMac model and slot layout

Verify that your machine is the 27-inch Retina 5K iMac from Mid 2015 with model identifier iMac15,1 or part number MF885LL/A. The system supports a maximum of 32 GB across four slots, so this two-module kit leaves two sockets free for future expansion if required.

Steady throughput at rated JEDEC speed

Running at the standard 1600 MHz DDR3L frequency with 11-11-11 latency, the modules deliver consistent bandwidth during extended workloads such as video rendering or large dataset processing. The low 1.35 V voltage helps maintain stable thermals inside the all-in-one enclosure without active memory cooling.

Questions about this item

Does the kit contain everything needed for the iMac 27" 2015 upgrade or must anything else be purchased?

The box holds two 8 GB DDR3L 1600 SODIMM sticks — 16 GB total — which matches two of the four slots in the iMac 27" 2015; no extra parts are required.

Should I choose this 16 GB kit or a different capacity for the iMac 27" 2015?

This 16 GB (2×8 GB) kit fills half the slots and leaves room to reach the 32 GB maximum later; pick it if 16 GB meets today's workload and you want an easy upgrade path.

What does the 1600 MHz rating deliver once the modules are installed in the iMac 27" 2015?

The system runs the memory at DDR3L 1600 (PC3L 12800) with CL11 11-11-11 timing at 1.35 V, giving the rated bandwidth and latency for the Core i5 3.3 GHz model.
