iMac Late 2015 27 memory kit

This 32 GB kit contains two 16 GB DDR3 1866 SODIMM modules built for the iMac Late 2015 27 model. It uses 204 pin unbuffered non ECC chips at 1.35 V with CL13 latency. The kit targets owners who want the maximum supported capacity for that all in one desktop.

Verify slot count and model identifier

Confirm the computer is the iMac 17 1 Late 2015 27 inch Retina before ordering. The machine has two SODIMM slots so this two module kit fills both. Check the Apple menu About This Mac to match the exact model identifier and ensure the system accepts 16 GB per slot.

Low voltage DDR3 runs cool and quiet

The 1.35 V DDR3 modules produce minimal heat inside the sealed iMac chassis. No heat spreaders are fitted and the unbuffered design draws modest power during typical workloads. Expect silent operation with no added fan noise from the memory upgrade.
